VoiceStudio

VoiceStudio (formerly OmniVoice Studio) is a local, open source answer to ElevenLabs. It clones and designs voices, does text-to-speech across 16 engines and transcription across 11, dubs video by transcribing, translating and re-voicing it, builds audiobooks, and runs a system-wide dictation widget. The app is AGPL-3.0, free, and runs on your own machine.

A GPU is optional but makes the difference. Minimums are 8 GB of RAM and 10 GB of disk, and the default workflow wants 8 GB or more of VRAM on NVIDIA or Apple Silicon. ROCm is Linux-only and opt-in. Installers cover Apple Silicon Macs, Windows 10/11 and recent Linux; Docker images are amd64 only, and Intel Macs need a remote backend.

Solo creators and small teams doing voiceover, dubbing or audiobooks get no per-character billing and no audio leaving the machine. It also exposes a local REST API, an OpenAI-compatible audio API and an MCP server. Companies embedding it in a closed product can get a commercial license by enquiry, with no published price, and a hosted Cloud API is in early access.

The catch is the model licenses, not the app's. The default voice engine's pretrained weights are CC-BY-NC, noncommercial, so paid voiceover work means switching to an Apache-2.0 engine like CosyVoice 3 or VoxCPM2. It is still labeled active beta. Watermarking is on by default, but responsible voice cloning is on you.
