Why I Built an Open-Source ElevenLabs

Voice AI got good. Then it got rented.

The best cloning and dubbing live behind APIs: your voice goes to someone’s cloud, comes back priced per second, under terms that can change any quarter. For a demo, fine. For a studio you depend on — or a voice that happens to be yours — no.

So I built OmniVoice Studio: the open-source ElevenLabs alternative, as a desktop app. Clone, design, create, dub, dictate. Locally.

What’s inside

• Cloning and voice design — capture a voice or build one from scratch.
• Dubbing pipeline — cinematic, multi-track, end to end.
• Dictation — your machine, your microphone, your text.
• 600+ languages.
• Swappable engines — Whisper and friends, on your hardware: MLX on Apple silicon, CUDA on NVIDIA, Docker when you want it on a server.
• An OpenAPI surface — the studio doubles as a self-hosted API, so your tools can speak too.

Tauri desktop app around a Python core. Launchpad, studio, library, gallery — it’s built to be lived in, not demoed.

The bet

Voice is identity. It’s the most personal biometric you casually give away, and the current market structure is “upload it and subscribe to yourself.”

I bet people would rather own the stack. Just shy of 8,000 GitHub stars later, I’d say the bet is holding.

Enterprise-grade processing with nothing leaving your machine — that’s not a feature tier. That’s the point.

Your voice. Your hardware. Your studio.
