ComfyUI_Fill-ChatterBox

A custom node extension for ComfyUI that adds text-to-speech (TTS) and voice conversion (VC) capabilities using the Chatterbox library. Supports a MAXIMUM of 40 seconds. Iv tried removing this limitation, but the model falls apart really badly with anything longer than that, so it remains.

   cd /path/to/ComfyUI/custom_nodes
