What it does

Batch input and output, multiple candidate generations with validation, Whisper-based checking of what actually got spoken, denoising to strip artifacts, and a voice-conversion tab — a production pipeline rather than a demo. The knob count is the barrier: start with plain Chatterbox if this is your first TTS. Voice conversion is impersonation machinery, so restrict it to your own voice or one with explicit consent, and label synthetic audio. Quiet since August 2025. MIT.
