Fish Audio S2

Fish Audio S2 is the benchmark-topping open TTS — the most expressive self-hostable voice model, beating ElevenLabs on several independent tests.

Best for

• Tops independent 2026 TTS benchmarks (EmergentTTS-Eval, Audio Turing Test)
• Most expressive open-source / self-hostable TTS
• Fine-grained control + production streaming
• 80+ language coverage including many Asian languages

How it compares — and the India angle

• Self-hostable for free (non-commercial) — strong for Indian devs avoiding per-character API fees.
• Benchmark-beating quality vs ElevenLabs at lower hosted cost; check the licence before commercial Indian use.
• Good open alternative when ElevenLabs' commercial pricing is too high for Indian budgets.
