ComfyUI Voice Clone

Custom TTS node that clones voice from a reference audio and speaks entered text.

Install Voice Clone Custom Node

Install the ComfyUI Voice Clone custom node using the manager,

Or, install using your command/terminal prompt.

  1. Navigate to your ComfyUI/custom_nodes folder.
  2. Run, 
    git clone https://github.com/Sean-Bradley/ComfyUI-Voice-Clone.git
  3. Navigate to your ComfyUI_windows_portable folder.
  4. Run, 
    python_embeded\python -m pip install -r ComfyUI/custom_nodes/comfyui-voice-clone/requirements.txt
  5. Restart ComfyUI

Install Models

All required models can be downloaded from https://huggingface.co/Sean-Bradley/ComfyUI/tree/main/models/tts/chatterbox

Ensure that your folder structure and downloaded files resemble this below.

Settings

SettingDescription
exaggerationControls the expressiveness / prosody of the generated voice. Higher values make the speech more emphatic and varied; lower values produce a flatter, more neutral delivery. Valid range: 0.25 - 2.0.
temperatureSampling temperature for the text-to-speech decoder. Higher values increase randomness and variety in the generated audio; lower values make outputs more conservative and deterministic. Valid range: 0.15 - 2.0.
cfg_weightClassifier-free guidance (CFG) weight that balances adherence to the text conditioning vs. model priors. Larger values force the model to follow the conditioning (text/prompt) more strongly, which can improve faithfulness but may increase artifacts if set too high. Valid range: 0.05 - 1.0
min_pA lower-probability cutoff used during sampling to filter extremely unlikely tokens or frames. Helps avoid very low-probability outputs that could degrade quality. Valid range: 0.0 - 1.0
top_pNucleus (top-p) sampling cumulative probability threshold. The decoder samples from the smallest set of tokens whose cumulative probability β‰₯ top_p. top_p = 1.0 disables nucleus filtering (i.e., sample from full distribution). Valid range: 0.0 - 1.0
repetition_penaltyPenalizes repetition during generation. Values > 1.0 discourage repeating the same tokens/frames, reducing looping/redundancy in speech. Valid range: 1.0 - 2.0
voice_embedding (optional)If provided, an audio reference is used as an audio prompt for voice cloning.
disable_watermarkBy default, audio output is watermarked using PerTh Watermarking. You can disable this by selecting true.
