VoiceStudio
Local-first open-source voice cloning, dubbing, and audiobook studio.
Clone voices, dub videos, and design audio locally with 646 language support.
VoiceStudio is a desktop application designed for local voice cloning, video dubbing, and transcription. It suits audio producers and developers wanting to run speech models directly on their own hardware.
What it is
The application provides workspaces for voice cloning, voice design, video dubbing with timed speech, dictation, and audiobook creation. It defaults to the OmniVoice engine while supporting multiple alternative models and local API integrations.
Who it's for
It suits professionals and creators needing private, local control over voice synthesis and video dubbing workflows. It does not suit users looking for a simple web service without hardware setup requirements.
