Voice Studio

Voice Studio is a desktop application for generating speech from text using multiple open-source TTS models. It runs entirely offline on your machine with no cloud dependencies or API keys required. The tool supports seven engines (VibeVoice, Kokoro, Kitten TTS, Chatterbox, OmniVoice, VoxCPM2, and Qwen3-TTS), voice cloning from audio samples, multi-speaker podcast editing, and synthesis in over 30 languages.

Designed for creators, developers, and privacy-conscious users, Voice Studio offers four project modes: podcast editing, text-to-voice conversion, speech-to-text transcription (via Whisper), and audio dubbing. Only one TTS engine loads at a time to minimize memory usage. The project describes itself as an open-source alternative to ElevenLabs. According to the source, it was built using Claude Code.
