VoiceStudio: The Open-Source AI Voice Studio
VoiceStudio (formerly OmniVoice Studio) is a fully-local, open-source AI voice cloning and dubbing platform. It runs on your own machine — no account, no cloud upload, no subscription required. With support for 646 languages, it’s positioned as a privacy-first alternative to ElevenLabs and other cloud-based voice AI services.
What It Can Do
VoiceStudio ships with seven core capabilities, presented as a numbered feature carousel on the homepage:
| # | Feature | What It Does |
|---|---|---|
| 01 | Voice Clone | Mirror a voice from just three seconds of audio |
| 02 | Voice Design | Describe a voice in text — generate it |
| 03 | Video Dubbing | Dub any video into any language, preserving original timing |
| 04 | Stories | Cast a script; voice every role with distinct voices |
| 05 | Audiobook | A book in → chapters out (audiobook creation pipeline) |
| 06 | Voice Gallery | Ready-made voices to try out |
| 07 | Transcripts | Audio in → searchable text out |
Beyond the core features, VoiceStudio includes WorkflowStudio (a desktop workflow app), a Local API for programmatic access, and an optional Pro Cloud hosted tier (early access).
