VoiceStudio

VoiceStudio is an open-source desktop application for generating and working with synthetic speech locally. Its documented workflows include text-to-speech, zero-shot voice cloning, voice design, dictation, transcription, video dubbing, audiobook creation from EPUB or PDF files, and multi-voice stories. It supports multiple TTS and ASR engines, batch queues, speaker diarization, vocal isolation, watermarking, and GPU-aware engine routing.

The application is designed for user-controlled deployment on macOS, Windows, and Linux, with downloadable DMG, MSI, and AppImage releases plus Docker installation guidance. Processing runs on the user’s machine without accounts, API keys, or cloud dependence, while a remote-backend option is also documented. The project is licensed AGPL-3.0 and exposes an OpenAI-compatible API and MCP server.
