voicebox

A local-first voice I/O studio that exposes TTS, STT, and voice cloning to AI agents via an MCP server. Agents connect via MCP to call tools like voicebox.speak, voicebox.transcribe, and voicebox.list_profiles, with all audio processing running on-device for full privacy. Supports 7 TTS engines, Whisper-based dictation, and per-client voice binding for Claude Code, Cursor, and Windsurf.
