Voicebox
What is Voicebox?
Voicebox is an open-source, local-first AI voice studio for cloning voices, generating speech, transcribing audio, and dictating into desktop applications. It combines seven text-to-speech engines, Whisper-based speech recognition, local language models, audio effects, and multi-track story editing in one desktop app. Voicebox is designed for creators, developers, gamers, accessibility users, and anyone who wants voice workflows without sending recordings or transcripts to a cloud service. Its main differentiator is combining voice input, voice output, agent speech, and a local REST and MCP API on the user's own hardware. The desktop application is free, requires no account, and is available for macOS, Windows, Linux builds, and Docker.
How to use Voicebox?
1. Download and install Voicebox for your operating system, then launch the app without creating an account. 2. Import or record a voice sample, choose a TTS or Whisper model, and configure a voice profile. 3. Enter text or use the global dictation shortcut to generate, transcribe, edit, or export your first audio result.
