VoiceStudio

VoiceStudio is an open-source desktop app for local voice cloning, voice design, video dubbing, dictation, transcription, and audiobook creation. Its voice catalog covers 646 languages, with availability varying by engine.

It runs on macOS, Linux, and Windows through WSL. The app can clone a voice from a short clip, generate voices from descriptions, transcribe audio or video, translate and re-voice video while preserving speakers and timing, and create multi-voice or chaptered audiobooks from scripts and EPUB files.

VoiceStudio is available for local use without sending voice data to an external server. The site describes it as free for personal use and provides a shell-based installer and an open-source GitHub repository.
