Telnyx just launched NaturalHD, a new high-definition text-to-speech voice offering. It delivers crisper audio, better emotional nuance, and even handles natural disfluencies like “um,” “uh,” and light laughter without sounding robotic or broken.

This runs directly on their programmable Voice API and AI Assistant Builder. There’s no need to change your stack or carrier setup. All you need to do is update your voice parameter to use Telnyx NaturalHD.

Telnyx also supports Azure Neural HD and standard TTS, so you can balance performance and cost as needed, all from the same API.

Curious to hear your thoughts, especially from devs working with real-time voice AI.
