Why Voicebox?
Voice AI is exploding, but most tools are either cloud-locked, expensive, or a nightmare to set up. Voicebox is different:
- 100% Local — Your voice data never leaves your machine
- Lightweight — No bloated Electron, native Tauri performance
- Fast — Near-instant on CUDA, optimized for Apple Silicon
- Flexible — Use the app, integrate the API, or both
- Open Source — No subscriptions, no limits, no lock-in
Built with Tauri (Rust), TypeScript, React, and Python. Native performance meets modern DX.
Download
Voicebox is available now for macOS, Windows, and Linux.

API
Voicebox exposes a full REST API, so you can integrate voice synthesis into your own apps.
# Generate speech
curl -X POST http://localhost:8000/api/generate \
-H "Content-Type: application/json" \
-d '{"text": "Hello world", "profile_id": "abc123"}'
# List voice profiles
curl http://localhost:8000/api/profiles
# Create a profile from audio
curl -X POST http://localhost:8000/api/profiles \
-F "[email protected]" \
-F "name=My Voice"
Use cases:
- Game dialogue systems
- Podcast/video production pipelines
- Accessibility tools
- Voice assistants
- Content creation automation
Full API documentation available at http://localhost:8000/docs when running.
Tech Stack
| Layer | Technology |
|---|---|
| Desktop App | Tauri (Rust) |
| Frontend | React, TypeScript, Tailwind CSS |
| State | Zustand, React Query |
| Backend | FastAPI (Python) |
| Voice Model | Qwen3-TTS |
| Transcription | Whisper |
| Database | SQLite |
| Audio | WaveSurfer.js, librosa |
Why this stack?
- Tauri over Electron — 10x smaller bundle, native performance, lower memory
- FastAPI — Async Python with automatic OpenAPI schema generation
- Type-safe end-to-end — Generated TypeScript client from OpenAPI spec
Roadmap
Voicebox is the beginning of something bigger. Here's what's coming:
Coming Soon
| Feature | Description |
|---|---|
| Real-time Synthesis | Stream audio as it generates, word by word |
| Conversation Mode | Multi-speaker dialogues with automatic turn-taking |
| Voice Effects | Pitch shift, reverb, M3GAN-style effects |
| Timeline Editor | Audio studio with word-level precision editing |
| More Models | XTTS, Bark, and other open-source voice models |
Future Vision
- Voice Design — Create new voices from text descriptions
- Project System — Save and load complex multi-voice sessions
- Plugin Architecture — Extend with custom models and effects
- Mobile Companion — Control Voicebox from your phone
Voicebox aims to be the one-stop shop for everything voice — cloning, synthesis, editing, effects, and beyond.
