SpeakCrate

Private text to speech with multilingual voices and an OpenAI-compatible API

About SpeakCrate

SpeakCrate is an open-source, self-hosted text-to-speech API that turns text into speech for narration, read-aloud tools and voice-enabled applications on your own hardware, powered by the Kokoro model. It exposes an OpenAI-compatible POST /v1/audio/speech endpoint with 54 voices across nine languages including English, Japanese, Mandarin, Spanish and Hindi. Deploy with Docker on CPU or an NVIDIA GPU, output MP3, WAV, FLAC, Opus, AAC or PCM, stream audio as sentences are synthesized, and run fully offline once models are cached.
