Voicebox

Voicebox is an open-source voice cloning desktop application engineered by Qwen3-TTS technology. Primarily, it empowers users to produce natural-sounding speech from text, replicating any given voice with remarkable precision. Designed as a local-first voice cloning studio, Voicebox maintains the performance quality of professional voice synthesis, comparable to commercial alternatives. The entire process of cloning voices and generating speech takes place locally, without the need for any cloud services or subscriptions. Voicebox extends further functionality by including a stories editor for creating multi-voice narratives and an audio transcription system powered by Whisper for accurate speech-to-text service.

Indeed, Voicebox is free to use. It is an open-source application that does not demand any fee or subscription for its use or for accessing its source code.

Voicebox guarantees user privacy by operating on a local-first basis. Your voice data is neither sent nor stored on any remote servers since all operations, including voice cloning and speech generation, are done solely on your local machine without using any cloud services or requiring subscriptions.

Voicebox is designed to be cross-platform, compatible with macOS, Windows, and Linux.

Voicebox ensures the quality of voice cloning through its multi-sample support feature and the power of Qwen3-TTS technology. By using multiple voice samples, the chances of achieving higher quality and more natural-sounding results are enhanced. Qwen3-TTS technology, on the other hand, offers exceptional voice quality and accuracy.
