Free local VoiceStudio takes on ElevenLabs on Windows

VoiceStudio follows a familiar open-source pattern: take a capable model and wrap it in a desktop app that keeps data on the machine. Its default engine, OmniVoice, is described as a large multilingual zero-shot text-to-speech model supporting more than 600 languages, and the tool builds cloning, voice design, dubbing, transcription, dictation and audiobook creation around it rather than offering a single function.

The dubbing feature is the most involved. It transcribes the dialogue in a video, translates it and replaces it with synthesized speech, identifying different speakers so each gets a matching voice, while keeping the original background music and sound effects and exporting to MP4. Audiobook creation splits long text into chapters and can assign different voices to different characters.

There are practical limits. Voice design flexibility depends on the engine chosen, since OmniVoice exposes a fixed set of traits such as gender, age and pitch. The app and the voice models carry separate terms, so anyone planning commercial use should check both the model license and the rights to the voice material.
