What Is Fish Speech? Fish Speech 是什么？
Fish Speech is an open-source project with 32k+ GitHub stars. Brand new TTS solution with voice cloning
The project focuses on speech, tts, cloning use cases and is designed as a ready-to-use application—you can deploy or run it directly without writing integration code.
Source code is available at github.com/fishaudio/fish-speech. With 32k+ GitHub stars, it ranks among the most battle-tested open-source tools in this space—meaning most common use cases are well-documented with community solutions available.
Podcast creators can produce multilingual episodes with authentic voice variants using just 10-30 seconds of audio per character, eliminating expensive studio sessions. Unlike ElevenLabs' cloud dependency, Fish Speech's open-source approach (31k+ stars) enables offline processing and cost-free scaling. However, teams requiring enterprise SLAs and production support should look elsewhere, as community-driven projects lack guaranteed uptime.
