Product Description
The world's most realistic voice AI, in real-time
Prompt the first LLM for text-to-speech to create new voices, instruct emotions, and more
A text-to-speech system that understands what it's saying
Octave (Omni-capable text and voice engine) isn't a traditional TTS model. It’s a voice-based LLM. That means it understands what words mean in context, so it can predict emotions, cadence, and more.
Create any voice you can imagine with Octave Voice Design
Any emotion or speaking style, on command
Octave is the first TTS system that can take natural language instructions to change emotional delivery and speaking style. Give directions like "sound sarcastic" or "whisper fearfully." For the first time, creators have total control.
For creators and developers alike
Octave was built to generate the most expressive AI voices for any content: podcasts, voiceovers, audiobooks, and more. With our API, you can bring it to any application.

We research foundation models and how to align them with human well-being
