ComfyUI-IndexTTS2
|
|
=================
|
|
|
|
Lightweight ComfyUI wrapper for IndexTTS 2 (voice cloning + emotion control). The nodes call the original IndexTTS2 inference and keep behavior faithful to the repo.
|
|
|
|
Original repo: https://github.com/index-tts/index-tts
|
|
|
|
Install
|
|
- Copy this folder to: ComfyUI/custom_nodes/ComfyUI-IndexTTS2
|
|
- In your ComfyUI Python environment: pip install -r requirements.txt
|
|
- Recommended: install PyTorch with CUDA for GPU inference.
|
|
|
|
Models (checkpoints)
|
|
- Download ALL files and subfolders from Hugging Face and put them under this extension's checkpoints/ folder, preserving the original structure:

|
- Example layout:

Nodes
|
|
- IndexTTS2 Simple
|
|
- Inputs: audio (speaker), text, emotion_control_weight (0.0-1.0), emotion_audio (optional), emotion_vector (optional)
|
|
- Outputs: AUDIO (for Preview/Save), STRING (emotion source message)
|
|
|
|
- Notes: device auto-detected, FP16 on CUDA, 200 ms pause between segments (fixed), emotion precedence = vector > second audio > original audio
|
|
|
|
- IndexTTS2 Emotion Vector
|
|
- 8 sliders (0.0-1.4) for: happy, angry, sad, afraid, disgusted, melancholic, surprised, calm
|
|
- Constraint: sum of sliders must be <= 1.5 (no auto-scaling)
|
|
- Output: EMOTION_VECTOR
|
|
|
|
- IndexTTS2 Emotion From Text (optional)
|
|
- Input: short descriptive text
|
|
- Requires: modelscope and local QwenEmotion at checkpoints/qwen0.6bemo4-merge/
|
|
- Outputs: EMOTION_VECTOR, STRING summary
|
|
|
|
Examples
|
|
- Basic: Load Audio -> IndexTTS2 Simple -> Preview/Save Audio
|
|
- Second audio emotion: Load Audio (speaker) + Load Audio (emotion) -> IndexTTS2 Simple -> Save
|
|
- Vector emotion: IndexTTS2 Emotion Vector -> IndexTTS2 Simple -> Save
|
|
- Text emotion: IndexTTS2 Emotion From Text -> IndexTTS2 Simple -> Save
|
|
|
|
|
|
|
|
Troubleshooting
|
|
- Emotion vector sum exceeds maximum 1.5: lower one or more sliders or adjust the text-derived vector.
|
|
- BigVGAN kernel message: custom CUDA kernel is disabled by default; falls back to PyTorch ops.
