Desktop voice studio: zero-shot cloning, 7 TTS engines (Qwen3-TTS, Chatterbox, Kokoro, and more), 23 languages, global hotkey dictation into any field, effects, and MCP-aware agent voice hooks. Docs at docs.voicebox.sh. GH trending signal with ★~55k — privacy-first local voice I/O for builders, not another cloud TTS signup.","theCatch":"Local GPU/CPU and model downloads are on you; macOS/Windows desktop footprint is heavier than a REST TTS call. Large open-issue count — treat cutting-edge engines as experimental. Vs ElevenLabs-class cloud TTS (paid APIs) and Whisper-only STT stacks: Voicebox owns both ends of the loop locally, with agent voice as a first-class surface.","verdict":"MIT local voice studio. Install when agents and humans need on-device TTS/STT without a cloud voice vendor.","addedAt":"2026-09-17","featured":false,"domain":"Libraries","subSpecialty":"Libraries","subcategory":"Media & Audio","tags":["mcp","self-host","local-first","permissive","voice","active","fast-stars"],"capabilities":["mcp"],"surfaces":["MCP","Self-host"],"ecosystem":["Node.js"],"licenseModel":"OSS/MIT","githubStars":57963,"starsPerWeek":1516,"access":"free","archived":false,"repo":{"createdAt":"2026-01-25","pushedAt":"2026-10-07","license":"MIT","archived":false,"checkedAt":"2026-10-19"}},"related":[{"slug":"hono","name":"Hono","tagline":"Tiny TypeScript web framework that runs on every runtime"},{"slug":"phaser","name":"Phaser","tagline":"MIT HTML5 2D game framework with scenes, physics, and tilemaps"},{"slug":"pixijs","name":"PixiJS","tagline":"MIT 2D WebGPU/WebGL renderer, not a game engine"},{"slug":"babylonjs","name":"Babylon.js","tagline":"Apache-2.0 3D engine for the web, now on v9"},{"slug":"playcanvas","name":"PlayCanvas","tagline":"MIT WebGL2/WebGPU engine plus an optional hosted Editor"}],"links":{"self":"/api/gems/voicebox","html":"/gems/voicebox","markdown":"/gems/voicebox.md","category":"/api/gems?category=libraries","categoryPage":"/stacks/libraries"}}
