Moonshine
Moonshine is an on-device speech processing tool providing transcription, voice synthesis, and voice agents.
Moonshine Voice provides speech to text, text to speech, dictation, and voice agents running entirely in your browser via WebAssembly. The models download once and run on your own CPU without requiring an API key or an account, ensuring no audio leaves your device. It offers live transcription with per-phrase latency, natural voices in 16 languages, and zero-shot voice cloning from four seconds of speech. Users can build voice interfaces with multi-step spoken conversation triggered by meaning. It also includes finished applications for dictation with Markdown and Word export, as well as meeting notes transcription with speaker identification and audio playback.
