Open-source text-to-speech tuned for natural conversation
Tuned for dialogue rather than narration, so output carries natural rhythm, pauses and intonation that suits assistant-style speech.
Handles both languages, making it practical for multilingual assistant experiences and content that switches between them.
Code and pretrained weights are publicly available, so you can run it locally, inspect it and fine-tune it on your own audio.
Install with pip, load the model, pass a list of text strings and receive waveform arrays ready to play or save.
Open-weights 8B text-to-speech for expressive English speech, with a hosted demo to try it first.
A roughly 8-billion-parameter text-to-speech checkpoint with public weights and inference code, aimed at expressive English conversational speech rather than generic narration.
The model can condition on prompt audio, which is what makes voice continuation and one-shot cloning evaluations possible — intended for use with consented audio only.
A browser interface with a catalogue of studio voices, script-to-audio generation, 48 kHz previews, streaming captions and a live translation draft for creator workflows.
Miso Labs frames the model around conversational latency, including a published 110 ms claim that the site recommends benchmarking yourself against your own hardware and prompt lengths.
