This is a good release if they're not too cherry picked!
I say this every time it comes up, and it's not as sexy to work on, but in my experiments voice AI is really held back by transcription, not TTS. Unless that's changed recently.
ianbicking · 1d ago
FWIW in my recent experience I've found LLMs are very good at reading through the transcription errors
(I've yet to experiment with giving the LLM alternate transcriptions or confidence levels, but I bet they could make good use of that too)
vunderba · 1d ago
Pairing speech recognition with a LLM acting as a post-processor is a pretty good approach.
I put together a script a while back which converts any passed audio file (wav, mp3, etc.), normalizes the audio, passes it to ggerganov whisper for transcription, and then forwards to an LLM to clean the text. I've used it with a pretty high rate of success on some of my very old and poorly recorded voice dictation recordings from over a decade ago.
An LLM step also works pretty well for diarization. You get a transcript with speaker-segmentation (with whisper and pyannote for example), SPEAKER_01 says at some point „Hi I’m Bob. And here’s Alice“, SPEAKER_02 says „Hi Bob“ and now the LLM can infer that SPEAKER_01 = Bob and SPEAKER_02 = Alice.
soulofmischief · 1d ago
Yep, my agent i built years ago worked very well with this approach, using a whisper-pyannote combo. The fun part is knowning when to end transcription in noisy environments like a coffee shop.
Tokumei-no-hito · 1d ago
thanks for sharing. are some local models better than others? can small models work well or do you want 8B+?
vunderba · 1d ago
So in my experience smaller models tend to produce worse results BUT I actually got really good transcription cleanup with CoT (Chain of Thought models) like Qwen even quantized down to 8b.
dragonwriter · 23h ago
I think the 8B+ question was about parameter count (8 billion+ parameters), not quantization level (8 bits per weight).
vunderba · 21h ago
Yeah I should have been more specific - Qwen 8b at a 5_K_M quant worked very well.
mikepurvis · 1d ago
I was going to say, ideally you’d be able to funnel alternates to the LLM, because it would be vastly better equipped to judge what is a reasonable next word than a purely phonetic model.
ianbicking · 1d ago
If you just give the transcript, and tell the LLM it is a voice transcript with possible errors, then it actually does a great job in most cases. I mostly have problems with mistranscriptions saying something entirely plausible but not at all what I said. Because the STT engine is trying to make a semantically valid transcription it often produces grammatically correct, semantically plausible, and incorrect transcriptions. These really foil the LLM.
Even if you can just mark the text as suspicious I think in an interactive application this would give the LLM enough information to confirm what you were saying when a really critical piece of text is low confidence. The LLM doesn't just know what are the most plausible words and phrases for the user to say, but the LLM can also evaluate if the overall gist is high or low confidence, and if the resulting action is high or low risk.
miki123211 · 1d ago
This is actually something people used to do.
old ASR systems (even models like Wav2vec) were usually combined with a language model. It wasn't a large language model, those didn't exist at the time, it was usually something based on n-grams.
throwawaymaths · 1d ago
do you know if any current locally hostable public transcribers are good at diarization? for some tasks having even crude diarization would improve QOL by a huge factor. i was looking at a whisper diarization python package for a bit but it was a bitch to deploy.
yeah as i said, i couldn't figure out how to deploy whisper-diarization.
genewitch · 17h ago
so you need python - a full install, and git. Doesn't matter OS. python venv (virtual environment) ensures that this folder, once it works, is locked to all the versions inside it, including the python version. this works for any software that uses pip to set up, or any python stuff in general.
git clone <whisper-diarization.git URL>
cd whisper-diarization
python -m venv .
cd scripts
# and then depending on your OS it's activate.sh, activate.ps1, activate.bat, etc. so on linux [0]
your prompt should change to say
(whisper-diarization) <your OS prompt>$
now you can type
cd ..
pip install -c constraints.txt -r requirements.txt
python ./diarize.py --no-stem --suppress_numerals --whisper-model large-v3-turbo --device cuda -a <FILE>
next time you want to use it, you can just do like
cd ~/whisper-diarization
scripts/activate.sh (or whatever) [0]
python ./diarize.py [...]
[0]
To activate a Python virtual environment created with venv, use the command
source venv/bin/activate
on Linux or macOS, or
venv\Scripts\activate
on Windows. This will change your terminal prompt to indicate that the virtual environment is active.
(the [0] note was 'AI generated' by DDG, but whatever, linux puts it in ./bin/activate and windows puts it in ./Scripts/activate.ps1 (ideally))

> Any of you fucking pricks move and I'll execute every motherfucking last one of you.
I'm so tired of the boring old "miss daisy" demos.
People in the indie TTS community often use the Navy Seals copypasta [1, 2]. It's refreshing to see Resemble using swear words themselves.
Sadly they don't publish any training or fine tuning code, so this isn't "open" in the way that Flux or Stable Diffusion are "open".
If you want better "open" models, these all sound better for zero shot:
Zeroshot TTS: MaskGCT, MegaTTS3
Zeroshot VC: Seed-VC, MegaTTS3
Granted, only Seed-VC has training/fine tuning code, but all of these models sound better than Chatterbox. So if you're going to deal with something you can't fine tune and you need a better zero shot fit to your voice, use one of these models instead. (Especially ByteDance's MegaTTS3. ByteDance research runs circles around most TTS research teams except for ElevenLabs. They've got way more money and PhD researchers than the smaller labs, plus a copious amount of training data.)

It makes my Australian accent sound very English though, in a posh RP way.
Very natural sounding, but not at all recreating my accent.
Still, amazingly clear and perfect for most TTS uses where you aren't actually impersonating anyone.
skatanski · 1d ago
How does it work from the privacy standpoint? Can they use recorded samples for training?
Gave your wrapper a try and, wow, I'm blown away by both Chatterbox TTS and your API wrapper.
Excuse the rudimentary level of what follows.
Was looking for a quick and dirty CLI incantation to specify a local text file instead of the inline `input` object, but couldn't figure it.
Pointers much appreciated.
travisvn · 18h ago
This API wrapper was initially made to support a particular use case where someone's running, say, Open WebUI or AnythingLLM or some other local LLM frontend.
A lot of these frontends have an option for using OpenAI's TTS API, and some of them allow you to specify the URL for that endpoint, allowing for "drop-in replacements" like this project.
So the speech generation endpoint in the API is designed to fill that niche. However, its usage is pretty basic and there are curl statements in the README for testing your setup.
Anyway, to get to your actual question, let me see if I can whip something up. I'll edit this comment with the command if I can swing it.
In the meantime, can I assume your local text files are actual `.txt` files?
mistersquid · 18h ago
This is way more of a response than I could have even hoped for. Thank you so much.
To answer your question, yes, my local text files are .txt files.
travisvn · 18h ago
Ok, here's a command that works.
I'm new to actually commenting on HN as opposed to just lurking, so I hope this formatting works..
Just replace the `your_file.txt` with.. well, you get it.
This'll hopefully handle any potential issues you'd have with quotes or other symbols breaking the JSON input.
Let me know how it goes!
Oh and you might want to change `python3` to `python` depending on your setup.
mistersquid · 18h ago
> Just replace the `your_file.txt` with.. well, you get it.

Wow. I'm humbled and grateful.
I'll update once I'm done with work and back in front of my hone nachine.
travisvn · 11h ago
Hey — just pushed a big update that adds an (opt-in) frontend to test the API
For now, there's just a textarea for input (so you'll have to copy the `.txt` contents) — but it's a lot easier than trying to finagle into a `curl` request
Let me know if you have any issues!
mistersquid · 9h ago
(Didn't carefully read your reply. What follows are the results of cat-ing a text file in the CLI. Will give the new textbox a whirl in the morning PDT. A truly heartfelt thanks for helping me work with Chatterbox TTS!)
Absolutely blown away.
I fed it the first page of Gibson's "Neuromancer" and your incantation worked like a charm. Thanks for the shell script pipe mojo.
Some other details:
- 3:01 (3 mins, 1 sec) of generated .wav took 4:28 to process
- running on M4 Max with 128GB RAM
- Chatterbox TTS inserted a few strange artifacts which sounded like air venting, machine whirring, and vehicles passing. Very odd and, oddly, apropos for cyberpunk.
- Chatterbox TTS managed to enunciate the dialog _as_ dialog, even going so far as to mimick an Australian accent where the speaker was identified as such. (This might be the effect of wishful listening.)
I am astounded.
venusenvy47 · 1d ago
Would this be usable on a PC without a GPU?
travisvn · 19h ago
It can definitely run on CPU — but I'm not sure if it can run on a machine without a GPU entirely.
To be honest, it uses a decently large amount of resources. If you had a GPU, you could expect about 4-5 gb memory usage. And given the optimizations for tensors on GPUs, I'm not sure how well things would work "CPU only".
If you try it, let me know. There are some "CPU" Docker builds in the repo you could look at for guidance.
> Every audio file generated by Chatterbox includes Resemble AI's Perth (Perceptual Threshold) Watermarker - imperceptible neural watermarks that survive MP3 compression, audio editing, and common manipulations while maintaining nearly 100% detection accuracy.
I thought the point of this sort of watermark was that it was embedded somehow in the model weights, so that it couldn't easily be separated out. If you're going to release an open-source model that adds a watermark as a separate post-processing step, then why bother with the watermark at all?
jchw · 1d ago
Possibly a sort of CYA gesture, kinda like how original Stable Diffusion had a content filter IIRC. Could also just be to prevent people from accidentally getting peanut butter in the toothpaste WRT training data, too.
throw101010 · 1d ago
Stable Diffusion or rather Automatic1111 which was initially the UI of choice for SD models had a joke/fake "watermark" setting too which was deliberately doing nothing besides poking fun at people who were thinking that open source projects would really waste time on developing something that could easily be stripped/reverted by the virtue of being open source anyways.
vunderba · 1d ago
Yeah, there's even a flag to turn it off in the parser `--no-watermark`. I assumed they added it for downstream users pulling it in as a "feature" for their larger product.
echelon · 1d ago
1. Any non-OpenAI, non-Google, non-ElevenLabs player is going to have to aggressively open source or they'll become 100% irrelevant. The TTS market leaders are obvious and deeply entrenched, and Resemble, Play(HT), et al. have to aggressively cater to developers by offering up their weights [1].
2. This is CYA for that. Without watermarking, there will be cries from the media about abuse (from anti-AI outfits like 404Media [2] especially).
[1] This is the right way to do it. Offer source code and weights, offer their own API/fine tuning so developers don't have to deal with the hassle. That's how they win back some market share.
> For now, that means we’re not releasing the training code, and fine-tuning will be something we support through our paid API (https://app.resemble.ai). This helps us pay the bills and keep pushing out models that (hopefully) benefit everyone.
Big bummer here, Resemble. This is not at all open.
For everyone stumbling upon this, there are better "open weights" models than Resemble's Chatterbox TTS:
Zeroshot TTS: MaskGCT, MegaTTS3
Zeroshot VC: Seed-VC, MegaTTS3
These are really good robust models that score higher in openness.
Unfortunately only Seed-VC is fully open. But all of the above still beat Resemble's Chatterbox in zero shot MOS (we tested a lot), especially the mega-OP Chinese models.
(ByteDance slaps with all things AI. Their new secretive video model is better than Veo 3, if you haven't already seen it [2]!)
You can totally ignore this model masquerading as "open". Resemble isn't really being generous at all here, and this is some cheap wool over the eyes trickery. They know they retain all of the cards here, and really - if you're just going to use an API, why not just use ElevenLabs?
Shame on y'all, Resemble. This isn't "open" AI.
The Chinese are going to wipe the floor with TTS. ByteDance released their model in a more open manner than yours, and it sounds way better and generalizes to voices with higher speaker similarity.
Playing with open source is a path forward, but it has to be in good faith. Please do better.
[1] "10/10" open includes: 1. model code, 2. training code, 3. fine tuning code, 4. inference code, 5. raw training data, 6. processed training data, 7. weights, 8. license to outputs, 9. research paper, 10. patents. For something to be a good model, it should have 7/10 or above.
The weights are indeed open (both accessible and licensing-wise): you don't need to put that in square quotes. Training code is not. You can fine-tune the weights yourself with your own training code. Saying that isn't open is like saying ffmpeg isn't open because it doesn't do everything I need it to do and I have to wrap it with own code to achieve my goals.
dragonwriter · 20h ago
It really weird to say ByteDance’s release is “more open” when the WaveVAE encoder isn't released at all, only the decoder, so new voices require submitting your sample to a public GDrive folder and getting extracted latents back through another public GDrive folder.
pmarreck · 17h ago
FYI, the term is scare quotes (because they imply suspicion), not square quotes
echelon · 1d ago
Machine learning assets are not binary "open" or "closed". There is a continuum of openness.
To make a really poor analogy, this repo is like a version of Linux that you can't cross-compile or port.
To make another really poor (but fitting) analogy, this is like an "open core" SaaS platform that you know you'll never be able to run the features that matter on your own.
This repo scores really low on the "openness" continuum. In this case, you're very limited in what you can do with Chatterbox TTS. You certainly can't improve it or fit it to your data.
> You can fine-tune the weights yourself with your own training code.
This will never be built by anyone, and they know that. If it could be, they'd provide it themselves.
If you're considering Chatterbox TTS, just use MegaTTS3 [1] instead. It's better by all accounts.
> This will never be built by anyone, and they know that. If it could be, they'd provide it themselves.
Community fine-tuning code has been developed in the past for open-weights models without public first-party training code.
fastball · 1d ago
Why can't you improve it or fit it to your data?
This can be cross-compiled/ported in the Linux analogy. The Linux analogy would be more like: a kernel dev wrote code for some part of the Linux kernel using JetBrains' CLion. He used features of CLion that made this process much easer than if he had written the code using `nano`. By your logic, the resulting kernel code is not "open" because the tooling used to create it is not open. This is, of course, nonsense.
I agree that the project as a whole is less open than it could be, but the weights are indeed as open as they can be, no scare quotes required.
echelon · 1d ago
I really don't think your analogy fits the absurdity of lacking the tooling. It's more like you have to decompile an N64 cartridge ROM and don't have the tools. But I don't want to play that game.
I'll up the ante. I'll bet you money that nobody forks this and adds fine tuning for at least a year.
You're supposed to wait to post this until I agree to the bet ;)
echelon · 23h ago
I'm totally humbled by this.
I haven't seen this level of involvement for a lot of the models I'm using, including several text to speech models.
The rapidity of this is also quite shocking. I don't think Resemble anticipated this either, given their wording on the aforementioned ticket.
There's probably a lot more work to do to ensure this works, adjusting learning rates, batching, etc., but it's all clearly being put into place and given attention. Even if this model has some finicky fine tuning behaviors, with this kind of willpower it'll be quickly overcome.
I suppose I owe you, haha.
tedip · 1d ago
Cant make everyone happy :)
echelon · 1d ago
This space is getting pretty crowded.
If you're going to drop weights on unsuspecting developers (who might not be familiar with TTS) and make them think that they'll fit their use case, that's a bit of a bait-and-switch.
Chatterbox TTS is only available over API for fine tunes. That's an incredibly saturated market, and there are better quality and cheaper models for this.
Chatterbox TTS is equivalent to already-released semi-open weights from ByteDance and other labs, and those models already sound and perform better.
It'd be truly exciting if Chatterbox fine tunes could be done as open weights, similar to how Flux operates. Black Forest Labs has an entire open weights ecosystem built around them. While they do withhold their pro / highest quality variants, they always release open weights with training code for each commercial release. That's a much better model for courting open source developers.
Another company doing "open weights" right is Lightricks with LTX-1. They have a commercial studio, but they release all of their weights and tuning code in the open.
I don't see how this is a carrot for open source. It's an ad for the hosted API.

The emotional exaggeration is interesting, though I don't think I've come across anything quite so versatile and easy to "sculpt" as Elevenlabs and it's ability to generate a voice on the basis of a description of how you want the voice to sound. SparkTTS allows some additional parameters, and it's project on GitHub has placeholders in its code that indicate the model might be refined for more fine grained emotional control. As it is, I've had some success with it and other models by trying to influence prosody and tonality with some heavy handed queues in the text, which can then be used with VC to get closer to desired results, but it's a much more cumbersome process than Eleven.
pryelluw · 1d ago
Silly question, what’s the lowest spec hardware this will run ?
But if the model is any good someone will probably find a way to optimize it to run on even less.
Edit: Got it running on an old Nvidia 2060, I'm seeing ~5 GB VRAM peak.
magicalhippo · 1d ago
Looking at the issues page, it seems it's not well optimized[1] currently.
So out of the box it seems quite beefy consumer hardware will be needed for it to perform reasonably. However it seems like there's significant potential for improvements, though I'm no expert.
I was going to report how it runs on an old CPU but after fussing with it for about 30 minutes, I can't even get it to run.
Listing the issues in case it helps anyone:
- It doesn't work with Python 3.13, luckily `uv` makes it easy to build a venv with 3.12
- It said numpy 1.26.4 doesn't exist. It definitely does, but `uv pip` was searching for it on the pytorch repo. I passed an `--index-strategy` flag so it would check other repos. This could just be a bug in uv, but when I see "numpy 1.26.4 doesn't exist" and numpy is currently on 2.x, my brain starts to cramp up.
- The `pip install chatterbox-tts` version has a bug in CPU-only mode, so I cloned the Git repo
- The version at the tip of main requires `protobuf-compiler` installed on Debian
- I got a weird CMake error that I can't decipher. I think maybe it's complaining that the Python dev headers are not installed. Why would they be, I'm trying to do inference, not compile Python...
I know anger isn't productive but this is my experience almost any time I'm running Somebody Else's Python Project. Hit an issue, back up, hit another issue, back up, after an hour it still doesn't run.

Are these things good enough to narrate a book convincingly or does the voice lose coherence after a few paragraphs being spoken?
vunderba · 1d ago
Most of these TTS systems tend to fall apart the longer the text - it's a good idea to just wrap any longform text into separate paragraph segmented batches and then stitch them back together again at the end.
I've also found that if your one-shot sample wave isn't really clean that sometimes Chatterbox produces random unholy whooshing sounds at the end of the generated audio which is an added bonus if you're recording Dante's Inferno.
Regarding your example "On a Google Colab's T4 GPU via Cuda, it takes about 5 minutes to convert "Animal's Farm"", do you know the approximate cost to perform this? I've only used Colab at the free level, so I have no concept of the costs for GPU time.

Once it's good enough Audible will be flooded with AI-narrated books so we'll know soon. (The only question is whether Amazon would disclose it, ofc)
landl0rd · 1d ago
Flip side is a solution where I can have a book without an audiobook auto-generated (or use an existing ebook rather than paying audible $30 for their version) and it's "good enough" is a legit improvement. AI generated isn't as good but it's better than nothing. Also, being able to interrupt and ask for more detail/context would be pretty nice. Like I'm reading some Pynchon and I have to stop sometimes and look up the name of a reference to some product nobody knows now, stuff like that.
skygazer · 1d ago
If you're willing to forgo the interactive LLM bit, kokoro-tts (just a script using Kokoro-ONNX) takes epubs and outputs a series of wavs or mp3s that need to be stitched together into chapters or audiobook m4a with some ffmpeg fu. I've listened to several generated audiobooks, and found them pretty good. Some nice generic narration-like prosody. It uses espeak-ng to generate phonemes and passes those to the model to render voice, so it generally pronounces things quite well. It comes with a handful of nice voices and several can be blended, but no easy voice cloning, like chatterbox, that I'm aware of.
I've used this repo and its great. It was one many things that inspired me in building a similar tool. I built https://desktop.with.audio
It was important to me that it be 100% private and local and wanted it to be a one time payment solution. Because it locally process your data it can be a one time payment text to speech app.
I've been using epub2tts / epub2tts-edge and its been working well for me. Converts into m4b
russellbeattie · 1d ago
Audible has already flooded their store with generated audio books. Go to the "Plus Catalog" and it's filled with them. The quality at the moment is complete trash, but I can't imagine it won't get better quickly.
The whole audiobook business will eventually disappear - probably within the decade. There will only be ebooks and on-device AI assistants will read it to you on demand.
I imagine it'll go like this: First pre-generated audiobooks as audio files. Next, online service to generate audio on demand with hyper customizable voices which can be downloaded. Next, a new ebook format which embeds instructions for narration and pronunciation to be read on-device. Finally, AI that's good enough to read it like a storyteller instantly without hints.
satvikpendem · 1d ago
> There will only be ebooks and on-device AI assistants will read it to you on demand.
Honestly I read (or rather, listen to) a lot of books already by getting the epubs onto my phone then using a very basic TTS to read it out. Yes, they're definitely not as lifelike as even the most common AI TTS systems but they're good enough to listen to at high speed. Moon+ Reader is pretty good for Android, not sure about iOS.
I consult a company in the space (not resemble) and I can definitely say it can narrate a book

the easiest way to defeat phone fraud is to ahead of time decide on a verbal password between family (and close friends, if they're close enough that you'd lend them money).
In a real scenario, they'd know the verbal password and you can authenticate them. Drum it into them that this password will prevent other people from impersonating you in this brave new world of ai voices and even video.
jimjimwii · 1d ago
That is more or less what i did with my parents, but this approach is still susceptible to active mitm attacks.
2 factor authentication through a secure app or a trusted family member is probably also needed though i haven't tackled this part with them yet.

> 2 factor authentication through a secure app
the problem is that the sort of emergency scenario in which family member would need the help is not often done or possible via a secured app. It's often just a telephone, with a number that you cannot recognize - imagine getting that phone call from a police station in the middle of nowhere when arrested, then you dont have access to any of your personal belongings as they're confiscated. The phone is a landline from the police station!
Therefore, a verbal password is needed, as this scenario is exactly how a scammer would present as the emergency that they need help (usually, wire some dollars to this account to bail out).

Interesting demo. A few observations, having uploaded a snippet of my own voice, and testing with some of my own text:
- the output had some of the qualities of my voice, but wasn't super similar. (Then again, the fact it could even do this from such a tiny snippet was impressive)
- increasing "CFG/pace" (whatever CFG is) even a little bit often just breaks down into total gibberish
- it was very inconsistent whether it would come out with a kind of British accent or an American one. (My accent is Australian...)
- the emotional exaggeration was interesting, but it seemed to vary a lot exactly what kind of emotion would come out

Does anyone know of an open-source TTS like this that can also encode speech to do voice conversion alongside TTS? i.e. a model that would take speech as input and convert it to one of the pretrained TTS voices.
Looks good!

dragonwriter · 20h ago
There are models that are trained for some kind of (in or out of band) emotiona (or style more general) prompting, but Chatterbox isn’t one of them, so beyond building some kind of system that took in input, processed it into chunks of text to speak and the settings Chatterbox does support (mostly pace and exaggeration) for each chunk, there’s probably no real way to do that with Chatterbox.

It's not on the same level in terms of emotion, but I believe the research https://github.com/CorentinJ/Real-Time-Voice-Cloning was based on is mostly oriented around Chinese first (and then English). It seems to work well enough if you and the voice you're cloning speak the same language though I haven't tested it much.
bachittle · 19h ago
I always have issues with TTS models that do not allow you to send large chunks of text. Seems this one does not resolve this either. Always has a limit of like 2-3 sentences.
I’d sign up for a service that calls a pharmacy on my behalf to refill prescriptions. In certain situations, pharmacies will not list prescriptions on their websites, even though they have the prescriptions on file, which forces the customer to call by phone — a frustrating process.
I do feel bad for pharmacists, their job is challenging in so many ways.

in my experience, TTS has been a "pick two" situation:

- can clone voices
- sounds super realistic
from what I can tell, Chatterbox is the first that apparently lets you pick 3! (have not tried it myself yet, this is just what I can deduce)
CGamesPlay · 1d ago

How does one train a TTS model with an LLM backbone? Practically, how does this work?
cyanf · 1d ago
you use a neural audio codec to encode audio into codebooks
then you could treat the codebook entries as tokens and treat audio generation as a next token prediction task
you then take the codebook entries generated and run it through the codec’s decoder and yield audio
it works surprisingly well

For what it's worth, there are also a whole bunch of models that speak Chinese.
So far the US and China are spearheading AI research, so it makes sense that models optimize for languages spoken there. Spanish is an interesting omission on the US part, but that's probably because most AI researchers in the US speak English even if their native tongue is Spanish.

TTS has been around as an initialism long before the current AI wave, the x2y pattern is newer. (You do see it around TTS, even though TTS itself hasn't become T2S; e.g., TTS toolchains often include a g2p—grapheme-to-phoneme—component.)
This is a good release if they're not too cherry picked!
I say this every time it comes up, and it's not as sexy to work on, but in my experiments voice AI is really held back by transcription, not TTS. Unless that's changed recently.
(I've yet to experiment with giving the LLM alternate transcriptions or confidence levels, but I bet they could make good use of that too)
I put together a script a while back which converts any passed audio file (wav, mp3, etc.), normalizes the audio, passes it to ggerganov whisper for transcription, and then forwards to an LLM to clean the text. I've used it with a pretty high rate of success on some of my very old and poorly recorded voice dictation recordings from over a decade ago.
Public gist in case anyone finds it useful:
https://gist.github.com/scpedicini/455409fe7656d3cca8959c123...
Even if you can just mark the text as suspicious I think in an interactive application this would give the LLM enough information to confirm what you were saying when a really critical piece of text is low confidence. The LLM doesn't just know what are the most plausible words and phrases for the user to say, but the LLM can also evaluate if the overall gist is high or low confidence, and if the resulting action is high or low risk.
old ASR systems (even models like Wav2vec) were usually combined with a language model. It wasn't a large language model, those didn't exist at the time, it was usually something based on n-grams.
(whisper-diarization) <your OS prompt>$
now you can type
next time you want to use it, you can just do like [0] To activate a Python virtual environment created with venv, use the command on Linux or macOS, or on Windows. This will change your terminal prompt to indicate that the virtual environment is active.(the [0] note was 'AI generated' by DDG, but whatever, linux puts it in ./bin/activate and windows puts it in ./Scripts/activate.ps1 (ideally))

I'm so tired of the boring old "miss daisy" demos.
People in the indie TTS community often use the Navy Seals copypasta [1, 2]. It's refreshing to see Resemble using swear words themselves.
They know how this will be used.

If you want better "open" models, these all sound better for zero shot:
Zeroshot TTS: MaskGCT, MegaTTS3
Zeroshot VC: Seed-VC, MegaTTS3
Granted, only Seed-VC has training/fine tuning code, but all of these models sound better than Chatterbox. So if you're going to deal with something you can't fine tune and you need a better zero shot fit to your voice, use one of these models instead. (Especially ByteDance's MegaTTS3. ByteDance research runs circles around most TTS research teams except for ElevenLabs. They've got way more money and PhD researchers than the smaller labs, plus a copious amount of training data.)

It makes my Australian accent sound very English though, in a posh RP way.
Very natural sounding, but not at all recreating my accent.
Still, amazingly clear and perfect for most TTS uses where you aren't actually impersonating anyone.
I created an API wrapper that also makes installation easier (Dockerized as well) https://github.com/travisvn/chatterbox-tts-api/
Best voice cloning option available locally by far, in my experience.
> I created an API wrapper that also makes installation easier (Dockerized as well) https://github.com/travisvn/chatterbox-tts-ap
Gave your wrapper a try and, wow, I'm blown away by both Chatterbox TTS and your API wrapper.
Excuse the rudimentary level of what follows.
Was looking for a quick and dirty CLI incantation to specify a local text file instead of the inline `input` object, but couldn't figure it.
Pointers much appreciated.
A lot of these frontends have an option for using OpenAI's TTS API, and some of them allow you to specify the URL for that endpoint, allowing for "drop-in replacements" like this project.
So the speech generation endpoint in the API is designed to fill that niche. However, its usage is pretty basic and there are curl statements in the README for testing your setup.
Anyway, to get to your actual question, let me see if I can whip something up. I'll edit this comment with the command if I can swing it.
In the meantime, can I assume your local text files are actual `.txt` files?
To answer your question, yes, my local text files are .txt files.
I'm new to actually commenting on HN as opposed to just lurking, so I hope this formatting works..
Just replace the `your_file.txt` with.. well, you get it.This'll hopefully handle any potential issues you'd have with quotes or other symbols breaking the JSON input.
Let me know how it goes!
Oh and you might want to change `python3` to `python` depending on your setup.
> This'll hopefully handle any potential issues you'd have with quotes or other symbols breaking the JSON input.
> Let me know how it goes!
Wow. I'm humbled and grateful.
I'll update once I'm done with work and back in front of my hone nachine.
For now, there's just a textarea for input (so you'll have to copy the `.txt` contents) — but it's a lot easier than trying to finagle into a `curl` request
Let me know if you have any issues!
Absolutely blown away.
I fed it the first page of Gibson's "Neuromancer" and your incantation worked like a charm. Thanks for the shell script pipe mojo.
Some other details:
I am astounded.To be honest, it uses a decently large amount of resources. If you had a GPU, you could expect about 4-5 gb memory usage. And given the optimizations for tensors on GPUs, I'm not sure how well things would work "CPU only".
If you try it, let me know. There are some "CPU" Docker builds in the repo you could look at for guidance.
If you want free TTS without using local resources, you could try edge-tts https://github.com/travisvn/openai-edge-tts
Am I misunderstanding, or can you trivially disable the watermark by simply commenting out the call to the apply_watermark function in tts.py? https://github.com/resemble-ai/chatterbox/blob/master/src/ch...
I thought the point of this sort of watermark was that it was embedded somehow in the model weights, so that it couldn't easily be separated out. If you're going to release an open-source model that adds a watermark as a separate post-processing step, then why bother with the watermark at all?
2. This is CYA for that. Without watermarking, there will be cries from the media about abuse (from anti-AI outfits like 404Media [2] especially).
[1] This is the right way to do it. Offer source code and weights, offer their own API/fine tuning so developers don't have to deal with the hassle. That's how they win back some market share.
[2] https://www.404media.co/wikipedia-pauses-ai-generated-summar...
https://github.com/resemble-ai/chatterbox/issues/45#issuecom...
> For now, that means we’re not releasing the training code, and fine-tuning will be something we support through our paid API (https://app.resemble.ai). This helps us pay the bills and keep pushing out models that (hopefully) benefit everyone.
Big bummer here, Resemble. This is not at all open.
For everyone stumbling upon this, there are better "open weights" models than Resemble's Chatterbox TTS:
Zeroshot TTS: MaskGCT, MegaTTS3
Zeroshot VC: Seed-VC, MegaTTS3
These are really good robust models that score higher in openness.
Unfortunately only Seed-VC is fully open. But all of the above still beat Resemble's Chatterbox in zero shot MOS (we tested a lot), especially the mega-OP Chinese models.
(ByteDance slaps with all things AI. Their new secretive video model is better than Veo 3, if you haven't already seen it [2]!)
You can totally ignore this model masquerading as "open". Resemble isn't really being generous at all here, and this is some cheap wool over the eyes trickery. They know they retain all of the cards here, and really - if you're just going to use an API, why not just use ElevenLabs?
Shame on y'all, Resemble. This isn't "open" AI.
The Chinese are going to wipe the floor with TTS. ByteDance released their model in a more open manner than yours, and it sounds way better and generalizes to voices with higher speaker similarity.
Playing with open source is a path forward, but it has to be in good faith. Please do better.
[1] "10/10" open includes: 1. model code, 2. training code, 3. fine tuning code, 4. inference code, 5. raw training data, 6. processed training data, 7. weights, 8. license to outputs, 9. research paper, 10. patents. For something to be a good model, it should have 7/10 or above.
[2] https://artificialanalysis.ai/text-to-video/arena?tab=leader...
To make a really poor analogy, this repo is like a version of Linux that you can't cross-compile or port.
To make another really poor (but fitting) analogy, this is like an "open core" SaaS platform that you know you'll never be able to run the features that matter on your own.
This repo scores really low on the "openness" continuum. In this case, you're very limited in what you can do with Chatterbox TTS. You certainly can't improve it or fit it to your data.
> You can fine-tune the weights yourself with your own training code.
This will never be built by anyone, and they know that. If it could be, they'd provide it themselves.
If you're considering Chatterbox TTS, just use MegaTTS3 [1] instead. It's better by all accounts.
[1] https://github.com/bytedance/MegaTTS3
Community fine-tuning code has been developed in the past for open-weights models without public first-party training code.
This can be cross-compiled/ported in the Linux analogy. The Linux analogy would be more like: a kernel dev wrote code for some part of the Linux kernel using JetBrains' CLion. He used features of CLion that made this process much easer than if he had written the code using `nano`. By your logic, the resulting kernel code is not "open" because the tooling used to create it is not open. This is, of course, nonsense.
I agree that the project as a whole is less open than it could be, but the weights are indeed as open as they can be, no scare quotes required.
I'll up the ante. I'll bet you money that nobody forks this and adds fine tuning for at least a year.
And someone else fine-tuned it for German: https://huggingface.co/SebastianBodza/Kartoffelbox-v0.1
I haven't seen this level of involvement for a lot of the models I'm using, including several text to speech models.
The rapidity of this is also quite shocking. I don't think Resemble anticipated this either, given their wording on the aforementioned ticket.
There's probably a lot more work to do to ensure this works, adjusting learning rates, batching, etc., but it's all clearly being put into place and given attention. Even if this model has some finicky fine tuning behaviors, with this kind of willpower it'll be quickly overcome.
I suppose I owe you, haha.
If you're going to drop weights on unsuspecting developers (who might not be familiar with TTS) and make them think that they'll fit their use case, that's a bit of a bait-and-switch.
Chatterbox TTS is only available over API for fine tunes. That's an incredibly saturated market, and there are better quality and cheaper models for this.
Chatterbox TTS is equivalent to already-released semi-open weights from ByteDance and other labs, and those models already sound and perform better.
It'd be truly exciting if Chatterbox fine tunes could be done as open weights, similar to how Flux operates. Black Forest Labs has an entire open weights ecosystem built around them. While they do withhold their pro / highest quality variants, they always release open weights with training code for each commercial release. That's a much better model for courting open source developers.
Another company doing "open weights" right is Lightricks with LTX-1. They have a commercial studio, but they release all of their weights and tuning code in the open.
I don't see how this is a carrot for open source. It's an ad for the hosted API.
it is highly amusing that they still believe they can put that genie back in the bottle with their usual crybully bullshit.
A lock needs not be infinitely strong to be useful, it just needs to take more resources to crack it than the locked thing is worth.

But if the model is any good someone will probably find a way to optimize it to run on even less.
Edit: Got it running on an old Nvidia 2060, I'm seeing ~5 GB VRAM peak.
So out of the box it seems quite beefy consumer hardware will be needed for it to perform reasonably. However it seems like there's significant potential for improvements, though I'm no expert.

Listing the issues in case it helps anyone:
- It doesn't work with Python 3.13, luckily `uv` makes it easy to build a venv with 3.12
- It said numpy 1.26.4 doesn't exist. It definitely does, but `uv pip` was searching for it on the pytorch repo. I passed an `--index-strategy` flag so it would check other repos. This could just be a bug in uv, but when I see "numpy 1.26.4 doesn't exist" and numpy is currently on 2.x, my brain starts to cramp up.
- The `pip install chatterbox-tts` version has a bug in CPU-only mode, so I cloned the Git repo
- The version at the tip of main requires `protobuf-compiler` installed on Debian
- I got a weird CMake error that I can't decipher. I think maybe it's complaining that the Python dev headers are not installed. Why would they be, I'm trying to do inference, not compile Python...
I know anger isn't productive but this is my experience almost any time I'm running Somebody Else's Python Project. Hit an issue, back up, hit another issue, back up, after an hour it still doesn't run.
> We developed and tested Chatterbox on Python 3.11 on Debain 11 OS; the versions of the dependencies are pinned in pyproject.toml to ensure consistency.
If something can be run for free but it's cheaper to rent, it voids the DIY aspect of it.
Funnily enough, it made my Australian accent sound very English RP. I was suddenly very posh.
I've also found that if your one-shot sample wave isn't really clean that sometimes Chatterbox produces random unholy whooshing sounds at the end of the generated audio which is an added bonus if you're recording Dante's Inferno.

The whole audiobook business will eventually disappear - probably within the decade. There will only be ebooks and on-device AI assistants will read it to you on demand.
I imagine it'll go like this: First pre-generated audiobooks as audio files. Next, online service to generate audio on demand with hyper customizable voices which can be downloaded. Next, a new ebook format which embeds instructions for narration and pronunciation to be read on-device. Finally, AI that's good enough to read it like a storyteller instantly without hints.
Honestly I read (or rather, listen to) a lot of books already by getting the epubs onto my phone then using a very basic TTS to read it out. Yes, they're definitely not as lifelike as even the most common AI TTS systems but they're good enough to listen to at high speed. Moon+ Reader is pretty good for Android, not sure about iOS.

Sadly it's closed source.
It's obviously an AI for playing wargames without having to bother painting all the miniatures, or finding someone with the same weird interest in Balkan engagements during the Napoleonic era.
- fast / cheap to run
- can clone voices
- sounds super realistic
from what I can tell, Chatterbox is the first that apparently lets you pick 3! (have not tried it myself yet, this is just what I can deduce)
Also, a deployable model: https://lightning.ai/bhimrajyadav/ai-hub/temp_01jwr0adpqf055...
then you could treat the codebook entries as tokens and treat audio generation as a next token prediction task
you then take the codebook entries generated and run it through the codec’s decoder and yield audio
it works surprisingly well
speech text models (tts model with an llm as backbone) is the current meta
> Currenlty only English.
meh
There’s eleven labs which is quite good but not incredible and very expensive.
Everything else ……. all the big AI companies …. have TTS systems that are kinda meh.
Everything else in AI has advanced in leaps and bounds, TTS remains deep in the uncanny valley.
So far the US and China are spearheading AI research, so it makes sense that models optimize for languages spoken there. Spanish is an interesting omission on the US part, but that's probably because most AI researchers in the US speak English even if their native tongue is Spanish.
