I read the comments praising these voices as very life like, and went to the page primed to hear very convincing voices. That is not at all what I heard though.
The voices are decent, but the intonation is off on almost every phrase, and there is a very clear robotic-sounding modulation. It's generally very impressive compared to many text-to-speech solutions from a few years ago, but for today, I find it very uninspiring. The AI generated voice you hear all over YouTube shorts is at least as good as most of the samples on this page.
The only part that seemed impressive to me was the English + (Mandarin?) Chinese sample, that one seemed to switch very seamlessly between the two. But this may well be simply because (1) I'm not familiar with any Chinese language, so I couldn't really judge the pronunciation of that, and (2) the different character systems make it extremely clear that the model needs to switch between different languages. Peut-être que cela n'aurait pas été si simple if it had been switching between two languages using the same writing system - I'm particularly curious how it would have read "simple" in the phrase above (I think it should be read with the French pronunication, for example).
And, of course, the singing part is painfully bad, I am very curious why they even included it.

Their comments about the singing and background music are odd. It’s been a while since I’ve done academic research, but something about those comments gave me a strong “we couldn’t figure out how to make background music go away in time for our paper submission, so we’re calling it a feature” vibe as opposed to a “we genuinely like this and think its a differentiator” vibe.

Is there any better model you can point at? I would be interested in having a listen.
There are people – and it does not matter what it's about – that will overstate the progress made (and others will understate it, case in point). Neither should put a damper on progress. This is the best I personally have heard so far, but I certainly might have missed something.
Uehreka · 9h ago
It’s tough to name the best local TTS since they all seem to trade off on quality and features and none of them are as good as ElevenLabs’ closed-source offering.
However Kokoro-82M is an absolute triumph in the small model space. It curbstomps models 10-20x its size in terms of quality while also being runnable on like, a Raspberry Pi. It’s the kind of thing I’m surprised even exists. Its downside is that it isn’t super expressive, but the af_heart voice is extremely clean, and Kokoro is way more reliable than other TTS models: It doesn’t have the common failure mode where you occasionally have a couple extra syllables thrown in because you picked a bad seed.
If you want something that can do convincing voice acting, either pay for ElevenLabs or keep waiting. If you’re trying to build a local AI assistant, Kokoro is perfect, just use that and check the space again in like 6 months to see if something’s beaten it. https://huggingface.co/hexgrad/Kokoro-82M

There's a lot of money and effort spent in satisfying the sexual desires of (predominantly straight) men. There's not typically quite as much interest in doing the same for women.
For example I've been looking at models and loras for generating images, and the boards are _full_ of ones that will generate women well or in some particular style. Quite often at least a couple of the preview images for each are hidden behind a button because they contain nudity. Clearly the intent is that they are at least able to generate porn containing women. There's a small handful that are focused on men and they're very aware of it, they all have notes lampshading how oddball they are to even exist.
I would expect that this is not as pronounced an effect in the world generating speech, but it must still exist.
lacy_tinpot · 4h ago
I think this is a very lazy kind of cultural analysis. The reason female voices are being chosen over male ones is a little more multifaceted than just SEX. Heterosexual women also tend to prefer female voices over male ones.
Female voices are often rated as being clearer, easier to understand, "warmer", etc.
Why this is the case is still an open question, but it's definitely more complex than just SEX.
selkin · 2h ago
That you consider it sex (rather than gender), is exactly why there’s a preference for female coded voices. Consider where we do hear male recorded voices used as default.

Overloaded term. It was a reference to the parent's reference.

This is clearly high quality but there's something about the voices, the male voices in particular, which immediately register as computer generated. My audio vocabulary is not rich enough to articulate what it is.
heeton · 11h ago
I'm no audio engineer either, but those computer voice sound "saw-tooth"y to me.
From what I understand, it's more basic models/techniques that are undersampling, so there is a series of audio pulses which give it that buzzy quality. Better models are produced smoother output.
I would describe it as blockly, as if we visualise the sound wave it seems to be without peaks and cut upwards and downwards producing a metallic boxy echo.

Is there a current, updated list (ideally, a ranking) of the best open weights TTS models?
I'm actually more interested in STT (ASR) but the choices there are rather limited.
Generally if a model is trending on that page, there’s enough juice for it to be worth a try. There’s a lot of subjective-opinion-having in this space, so beyond “is it trending on HF” the best eval is your own ears. But if something is not trending on HF it is unlikely to be much good.
Is there a way to filter out hosted models? The top three winners currently are all proprietary as far as I can tell.

TheAceOfHearts · 10h ago
Unfortunately it's not usable if you're GPU-poor. Couldn't figure out how to run this with an old 1080. I tried VibeVoice-1.5B on my old CPU with torch.float32 and it took 832 seconds to generate a 66 second audio clip. Switching from torch.bfloat16 also introduced some weird sound artifacts in the audio output. If you're GPU-poor the best TTS model I've tried so far is Kokoro.
Someone else mentioned in this thread that you cannot add annotations to the text to control the output. I think for these models to really level up there will have to be an intermediate step that takes your regular text as input and it generates an annotated output, which can be passed to the TTS model. That would give users way more control over the final output, since they would be able to inspect and tweak any details instead of expecting the model to get everything correctly in a single pass.
tempodox · 9h ago

Audiobooks and other material you want to listen to (articles, blog posts, etc.).
There's a lot of stuff I don't have time to sit down and read, but want to listen to while I cook/laundry/shower/drive/etc.
Often recordings don't exist. Or when they do, an audiobook just has a bad voiceover artist, or one that just rubs you the wrong way.
The more human text-to-speech sounds, the easier and less distracting it is to listen to. There's real value in it, it's not "because I can".
You know how it's nicer to read in 300 dpi instead of 72 dpi? Or in Garamond rather than Courier? Or in Helvetica rather than Comic Sans? It's like that, only for speech.
Ukv · 7h ago
> Question is why would you need to have the computer sound more human
I think translation would be a big use - maybe translating your voice to another language while maintaining emotion and intonation, or dubbing content (videos, movies, podcasts, ...) that isn't otherwise available in your native language.
Traditional non-ML TTS for longer content like podcasts or audiobooks seems like it'd become grating to the point of being unlistenable, or at least a significantly worse experience. Stands to benefit from more natural sounding voices that can place emphasis in the right places.
Since Stephen Hawking was brought up, there are likely also people with voice-impairing illnesses who would like to speak in their own voice again (in addition to those who are fine with a robotic voice). Or alternatively, people who are uncomfortable with their natural voice and want to communicate closer to how they wish to be perceived.
Could also potentially be used for new forms of interactive media that aren't currently feasible - customised movies, audio dramas where the listener plays a role, videogame NPCs that react with more than just prerecorded lines, etc.

Ok, this is nit-picking, but it's very obvious that the sample voices these were trained with were captured in different audio environments. There's noticeable reverb on the male voice that's not there on the other.

Yeah, a lot of the TTS has gotten really impressive in general. Definitely a clear leap from the TTS stuff I worked with for training simulations a bit over a decade ago.

I generally don't like a lot of the AI generated slop that's starting to pop up on YouTube these days... I do enjoy some of the reddit story channels, but have completely stopped with it all now. With the AI stuff, it really becomes apparent with dates/ages and when numbers are spoken. Dates/ages/timelines are just off as far as story generation, and really should be human tweaked. As to the voice gen, saying a year or measurement is just not how English speakers (US or otherwise) speak.

viggity · 11h ago
I feel like this is a step in the right direction, but a lot of emotive text-to-speech models are only changing the duration and loudness of each word, the timing/pauses are better too.
I would love to have a model that can make sense of things like stressing particular syllables or phonemes to make a point.
The voices are decent, but the intonation is off on almost every phrase, and there is a very clear robotic-sounding modulation. It's generally very impressive compared to many text-to-speech solutions from a few years ago, but for today, I find it very uninspiring. The AI generated voice you hear all over YouTube shorts is at least as good as most of the samples on this page.
The only part that seemed impressive to me was the English + (Mandarin?) Chinese sample, that one seemed to switch very seamlessly between the two. But this may well be simply because (1) I'm not familiar with any Chinese language, so I couldn't really judge the pronunciation of that, and (2) the different character systems make it extremely clear that the model needs to switch between different languages. Peut-être que cela n'aurait pas été si simple if it had been switching between two languages using the same writing system - I'm particularly curious how it would have read "simple" in the phrase above (I think it should be read with the French pronunication, for example).
And, of course, the singing part is painfully bad, I am very curious why they even included it.

llm-tts is far from complete, but it makes it relatively "easy" to try a few models in an uniform way.

Female voices are often rated as being clearer, easier to understand, "warmer", etc.
Why this is the case is still an open question, but it's definitely more complex than just SEX.
> satisfying the sexual desires of
So, "sex" as a reference to "sexual desires". In English, it just so happens that "sex" has other meanings, but those weren't in play at the time.
I trust the human scores in the paper. At least my ear aligns with that figure.
With stuff like this coming out in the open, I wonder if ElevenLabs will maintain its huge ARR lead in the field. I really don't see how they can continue to maintain a lead when their offering is getting trounced by open models.

I am not sure why but I find the pacing of the parakeet based models (like Dia) to be much more realistic.

From what I understand, it's more basic models/techniques that are undersampling, so there is a series of audio pulses which give it that buzzy quality. Better models are produced smoother output.

I'm actually more interested in STT (ASR) but the choices there are rather limited.
Generally if a model is trending on that page, there’s enough juice for it to be worth a try. There’s a lot of subjective-opinion-having in this space, so beyond “is it trending on HF” the best eval is your own ears. But if something is not trending on HF it is unlikely to be much good.
edit: Ah, there's a lock icon next to the name of each proprietary model.
Someone else mentioned in this thread that you cannot add annotations to the text to control the output. I think for these models to really level up there will have to be an intermediate step that takes your regular text as input and it generates an annotated output, which can be passed to the TTS model. That would give users way more control over the final output, since they would be able to inspect and tweak any details instead of expecting the model to get everything correctly in a single pass.
Compared to IBMs Steven Hawking's chair, maybe. But apple tts is not acceptable quality in any modern understanding of SotA, IMO.
If you need a not-visual output of text, SoyA is a waste of electrons.
If you want to try and mimic a human speaker, then it ain’t.
Question is why would you need to have the computer sound more human, except for “because I can”.
We can't be friends
There's a lot of stuff I don't have time to sit down and read, but want to listen to while I cook/laundry/shower/drive/etc.
Often recordings don't exist. Or when they do, an audiobook just has a bad voiceover artist, or one that just rubs you the wrong way.
The more human text-to-speech sounds, the easier and less distracting it is to listen to. There's real value in it, it's not "because I can".
You know how it's nicer to read in 300 dpi instead of 72 dpi? Or in Garamond rather than Courier? Or in Helvetica rather than Comic Sans? It's like that, only for speech.
I think translation would be a big use - maybe translating your voice to another language while maintaining emotion and intonation, or dubbing content (videos, movies, podcasts, ...) that isn't otherwise available in your native language.
Traditional non-ML TTS for longer content like podcasts or audiobooks seems like it'd become grating to the point of being unlistenable, or at least a significantly worse experience. Stands to benefit from more natural sounding voices that can place emphasis in the right places.
Since Stephen Hawking was brought up, there are likely also people with voice-impairing illnesses who would like to speak in their own voice again (in addition to those who are fine with a robotic voice). Or alternatively, people who are uncomfortable with their natural voice and want to communicate closer to how they wish to be perceived.
Could also potentially be used for new forms of interactive media that aren't currently feasible - customised movies, audio dramas where the listener plays a role, videogame NPCs that react with more than just prerecorded lines, etc.
Making it "open" would be unwise for a commercial entity. =3
For example, many academic data sets are not public domain, and can't be used in a commercial context. A GPL claim on that data is often an argument of which thief showed up first.
Rule #24: A lawyers Strategic Truth is to never lie, but also avoid voluntarily disclosing information that may help opponents.
Thus, a business will never disclose they paid a fool to break laws for them... =3
Indeed, these adversarial behaviors do not follow the spirit of FOSS community standards. If a project started as FOSS, than FOSS it should remain. =3
They could have skipped the singing part, it would be better if the model did not try to do that :)

But I do agree with you in that generally there's probably no negative connotation (yet).

Still not at the astonishing level of Google Notebook text to speech which has been out for a while now. I still can't believe how good that one is.
So that's a useful next step: for multi-voice TTS models, make them sound like they're in the same room.
Most that claim to do a British accent end up sounding like Kelsey Grammer - sort of an American accent pretending to be British.
edit: I had forgotten about Jai Ho (Slumdog Millionaire) and Lose Yourself (8 mile)
Nothing on that list - movies or songs - had the cultural impact of Furious 7 or See You Again.
Would probably want to do similar to balance crossfade anyway... having each speaker's input offset from center instead of straight mono.
I generally don't like a lot of the AI generated slop that's starting to pop up on YouTube these days... I do enjoy some of the reddit story channels, but have completely stopped with it all now. With the AI stuff, it really becomes apparent with dates/ages and when numbers are spoken. Dates/ages/timelines are just off as far as story generation, and really should be human tweaked. As to the voice gen, saying a year or measurement is just not how English speakers (US or otherwise) speak.
My usage is for Chinese, but the phonemes it generated looked very much like IPA.
No comments yet
It seems that it's only variants of English, Spanish and Chinese which are somewhat working.

In Android Auto / CarPlay I can't even get voice guidance that works properly, much less reading notifications, or composing a reply using STT

Or is there some OpenAI official Whisper TTS?
If you're in a company and need a model which one do you think you're getting past compliance & legal - the one that says MIT or the one that says "non-commercial use only"?
In fact, I think this kind of thing is absolutely necessary if you want to use this to replace a voice actor.

Some of them have tone wobbles which iirc was more common in early TTS models. Looks like the huge context window is really helping out here.
I would love to have a model that can make sense of things like stressing particular syllables or phonemes to make a point.
