@ansh_deb let me know if we can support with anything!
As a content creator - I've been looking for a product like this for a long time! Hope it'll match my expectations.

@yotam_dahan i think fish s2 would be the best for content creators! excited for you to try it, let us know what you think :)
Congrats on the launch! 🎉
The focus on emotion and nuance in TTS is really interesting. A lot of voice models sound technically good but still feel a bit flat, so the idea of capturing rhythm and speaking habits is compelling.
Also impressive that voice cloning works with just ~10 seconds of audio. Curious how you’re handling consent and voice ownership safeguards as this gets adopted more widely?

Fish Audio is hands down one of the most impressive TTS tools I've come across. I fed it a short clip and the output genuinely sounded like me. You can make your cloned voice whisper, laugh, get excited — it's funny and a little surreal hearing yourself say things in ways you never actually did . Can't believe this is open source. Great stuff, keep it up!
Congrats on the launch! I'm curious: if I’m building a real-time voice agent where latency and fine-grained emotion are dealbreakers, what specific benchmarks or features make Fish Audio a better bet than ElevenLabs right now?
Just found fish audio this year and was surprised about the API and the S1 model. Well, the S2 is now absolutely mind-blowing. Great work!
