## How the top CosyVoice alternatives compare

A closer look at the top 6: each CosyVoice alternative's standing among Text-to-speech APIs peers, its verdict record against CosyVoice, and the trade-offs of leaving.

### 1. Fish Speech

Among the 46 text-to-speech tools we track, Fish Speech has the 6th-widest language coverage - a fit for multilingual and localization projects.
In our published verdicts, Fish Speech beats CosyVoice for audiobooks, dubbing and voice agents.
The reverse angle matters too - CosyVoice vs Fish Speech: about half the languages.

**Why teams switch (Dubbing):** Dubbing and localization depends primarily on language coverage and voice cloning across those languages. Fish Speech supports 80 languages versus CosyVoice's 9 languages, a nearly 9x advantage. Both tools offer instant voice cloning, but Fish Speech's broader language support makes it vastly more feasible for multi-market dubbing workflows. The licensing difference (Apache-2.0 for CosyVoice vs custom non-commercial for Fish Speech) is a consideration, but the language coverage gap is decisive for this use case. [Dubbing verdict](https://www.versusref.com/tts/cosyvoice-vs-fish-speech/)

**Overall verdict:** Fish Speech wins 3 of the 4 use cases already decided. It supports 80 languages versus CosyVoice's 9 (facts 1f34c7da, 9f46db50), making it the stronger default for multilingual products like dubbing and localization. Its 31,300 GitHub stars versus 22,288 also signal broader community adoption. CosyVoice holds an edge for self-hosted deployments needing permissive Apache-2.0 licensing and lighter hardware, but that is a narrower audience. For most buyers, Fish Speech is the safer overall choice.
