❓ Frequently Asked Questions
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.
The role of Qwen3-TTS in Voicebox is significant. It forms the core engine for Voicebox, providing near-perfect voice cloning capabilities. Qwen3-TTS is responsible for the superior quality and accuracy of voice replication in Voicebox.
In Voicebox, local inference operations are accelerated using Metal and CUDA. Metal acceleration is leveraged on Mac devices, while CUDA acceleration is utilized on Windows/Linux systems. These are both GPU-based hardware acceleration technologies that speed up the process of voice cloning and speech synthesis.
With Voicebox, you can clone voices by first downloading a voice model. After that, you could use a few seconds of audio to clone any voice and create multi-voice projects using the studio-grade editing tools available within the application.
Yes, Voicebox operates fully without the requirement of a cloud service or subscription. It runs all voice cloning and speech generation functions entirely on your local machine.
Yes, Voicebox can run GPU inference locally. It makes use of Metal acceleration on Mac and CUDA acceleration on Windows/Linux systems to speed up local inference operations. Additionally, if desired, it also has the feature to connect to a remote machine for the GPU inference operations.
The Stories Editor in Voicebox provides a platform for users to craft multi-voice narratives with a timeline-based editor. It gives you the ability to arrange tracks, trim clips, and mix conversations, thereby offering a comprehensive editing environment.
The role of audio transcription in Voicebox is particularly substantial. Powered by Whisper, this function delivers accurate speech-to-text services, which in turn, facilitates the automatic extraction of reference text from voice samples. Essentially, Whisper makes this feature more accurate and efficient.
To generate natural-sounding speech from text using Voicebox, you first need to download a voice model. Once that's done, input your text within the app. Voicebox's underlying Qwen3-TTS technology will then convert your text into near-perfect voice-replicated speech.
Voicebox facilitates extraction of reference text from voice samples via its audio transcription system. This system, powered by Whisper's speech-to-text capabilities, transcribes voice samples and automatically extracts reference text.
