Users can generate speech through the graphical interface or via command-line automation, with outputs saved locally in standard audio formats. The application emphasizes privacy by keeping all data—scripts, voices, and generated audio—on the user’s machine without cloud uploads or third-party involvement. It operates offline after initial setup and supports Apple Silicon for faster-than-real-time processing.
