Details
The Fish Audio S2 API is the HTTP interface for the open-source Fish Speech S2-Pro TTS system, which uses a Dual-AR architecture to provide high-quality synthesis with a real-time factor of 0.195 on a single NVIDIA H200 GPU. The API supports around 50 languages, voice cloning, inline emotion control, multi-speaker generation, and streaming output. To use the API, you need to set up the Fish Speech S2-Pro server and an API client that can handle the binary audio responses. Apidog is recommended as it allows you to visually test the API, create mocks, validate responses, and listen to the generated audio without writing any code. The article walks through connecting Apidog to the API, making a basic TTS request, and performing voice cloning using the references endpoint.
