Fish Audio is an AI voice platform offering text-to-speech, voice cloning, speech-to-text, voice changing, and audio storytelling capabilities. The platform hosts a library of over two million voices across 30+ languages and is built around the Fish Speech open-source TTS model and the proprietary Fish Audio S2-Pro model. Fish Audio exposes a public REST API at api.fish.audio with first-party Python, Go, and TypeScript SDKs and supports voice cloning from as little as fifteen seconds of reference audio. The developer surface emphasizes ultra-low latency streaming, emotion control, and pay-as-you-go pricing for both prototype and production workloads.
