We've open-sourced Fish Audio S2, a new generation of expressive TTS that lets you direct voices with natural language. Add cues like [whisper] or [laughing nervously], generate multi-speaker dialogue in one pass, and create scary-real voices across 80+ languages.

Hi our beloved PH!
[excited] [slightly nervous]
Today we’re launching Fish Audio S2, our new text-to-speech model.
[long pause]
Hear Fish S2 Read This!
This is a big step beyond S1, redefining expressive voice AI. Write emotion cues anywhere in the text and hear the speech flow exactly how [emphasis] YOU direct it.
And, [inhale] we’re open-sourcing all of it.

@hehe6z Congrats on the launch! Curious how you see Fish Audio compared with ElevenLabs — what do you think are the biggest advantages or differences today?
@hehe6z best ai tool i ever found for my work

Can I use this in a raspberri pi voice assistant that I have at home?
What abour the voice cloning to use it in phone calls?
eleven labs is not that good.. ( or I dont know how to set it up)

@javierfandos Hi Javi, this is a great point - yes you absolutely can! For example home-assistant has direct fish audio support, you can check out the deets here: https://www.home-assistant.io/integrations/fish_audio/. Voice cloning is also one of the flagship features our users love because of the extreme realism :)

Klariqo AI Voice Assistants
@hehe6z That's amazing! Would love to give it a try soon!
Fish Audio
@ansh_deb let me know if we can support with anything!
How does Fish Audio maintain consistent emotional prosody and rhythmic nuance across long-form content, and what specific architectural improvements over So-VITS-SVC allow for such high-fidelity cloning from only 10 seconds of source audio?
Fish Audio
@mordrag great question Denis! S2 moves beyond systems like So-VITS-SVC and instead generates speech with a large speech-language model that operates on discrete audio tokens, which lets it maintain the traits over long passages. because S2 is heavily pretrained on large-scale speech data, the reference clip mainly anchors speaker identity and style, so it can clone voices extremely well from just 15 seconds of sample audio.
Cue
This is a big unlock for anyone building voice-driven products. Directing voices with natural language cues like [whisper] or [laughing nervously] instead of fiddling with sliders is so much more intuitive. Love that it's open source too. What languages are you seeing the most community demand for?
Fish Audio
@dparrelli Besides English a lot of Spanish, Chinese, and Japanese! Thank you for your support David!
