Our verdict
Fish Audio has quickly established itself as one of the leading AI voice synthesis platforms, largely thanks to its Fish-Speech open-source model available on GitHub. The commercial platform built around this model offers a complete experience from rapid voice cloning to high-quality multilingual text-to-speech. Fish Audio's absolute standout feature is the S2 Pro model: trained on 10 million hours of audio, it generates voices with remarkable naturalness and fine emotional control through 50 supported tags. The ability to clone a voice from just 10 seconds of source audio is impressive, even if 1–3 minutes remain recommended for optimal results. The community library of 200,000+ voices is a valuable resource for creators who don't want to build their own clones. The free plan at 8,000 monthly credits is sufficient for serious evaluation, but commercial use requires the Plus plan at $11/month. Fish Audio is especially compelling for developers and technical teams seeking to integrate quality TTS via API. Its open-source positioning builds trust and ensures long-term viability.
