What is OmniVoice Studio?
A desktop app for local dictation, zero-shot voice cloning from a 3-second clip, and video dubbing - all on-device. It markets itself as 'the open-source ElevenLabs alternative,' and it is a real, multi-OS app with native installers.
Pros & Cons
Pros
- Finished desktop app with native installers (macOS, Windows, Linux, Docker)
- Fully local, no API keys, broad engine choice (CosyVoice, MLX-Audio, VoxCPM2)
- Each release becomes Apache-2.0 two years after publication
Cons
- Active beta (v0.3.5) - things break between releases by the maintainer's own admission
- Despite the 'open-source' label, the license is FSL-1.1: source-available, not OSI-open
- Non-commercial / no 'competing use' until the 2-year Apache conversion
License
FSL-1.1-ALv2 (Source-available)
FSL-1.1-ALv2 - source-available, free for private and non-commercial use only. This is the most important correction to its own 'open-source' framing.
When it is interesting
Local, data-sovereign dubbing and dictation with no API costs.
When it is too early
Any commercial use without a purchased license, or production reliability.
