fish-voice-server

Host Fish Audio's open-weights voice models (Drama 3 and S2 Pro) on a serverless GPU (Modal, or fal) behind one small HTTP API a game can call. POST /speak takes text and a voice and streams 16-bit PCM back with first audio in ~0.4 s, cloned zero-shot from a reference clip, with [tags] like [angry] or [laughing] for delivery. Covers deploying with SGLang-Omni, the API, preparing voices at startup, keep-warm and cold starts, scaling to zero and cost, sampling settings that measurably help likeness, picking the best of several takes for pre-rendered lines, an optional S2 Pro fine-tune, and the setup gotchas. Use when a game, mod or app needs realtime cloned character voices, the user mentions Fish Audio, Fish Speech, S2 Pro, Drama 3 or a self-hosted TTS server, or a voice server is slow, cold or failing.
