<!-- ABOUT THE PROJECT -->
|
||||
## About The Project
|
||||
|
||||
This project brings the power of **VibeVoice** into the modular workflow of ComfyUI. VibeVoice is a novel framework by Microsoft for generating expressive, long-form, multi-speaker conversational audio. It excels at creating natural-sounding dialogue, podcasts, and more, with consistent voices for up to 4 speakers.
|
||||
|
||||
The custom node handles everything from model downloading and memory management to audio processing, allowing you to generate high-quality speech directly from a text script and reference audio files.
|
||||
|
||||
**Key Features:**
|
||||
* **Multi-Speaker TTS:** Generate conversations with up to 4 distinct voices in a single audio output.
|
||||
* **Zero-Shot Voice Cloning:** Use any audio file (`.wav`, `.mp3`) as a reference for a speaker's voice.
|
||||
* **Automatic Model Management:** Models are downloaded automatically from Hugging Face and managed efficiently by ComfyUI to save VRAM.
|
||||
* **Fine-Grained Control:** Adjust parameters like CFG scale, temperature, and sampling methods to tune the performance and style of the generated speech.
|
||||
* **4-Bit Quantization:** Run the large language model component in 4-bit mode to significantly reduce VRAM usage and improve speed on memory-constrained GPUs, especially for the 7B model.
|
||||
* **Transformers 4.56+ Compatibility:** Fully backwards compatible with both older and newer versions of the Transformers library.
|
||||
* **Force Offload Option:** Toggle to force model offloading from VRAM after generation to save memory between runs - now with improved ComfyUI compatibility.

||||

|
||||
|
||||
<!-- GETTING STARTED -->
|
||||
## Getting Started
|
||||
|
||||
Follow these steps to get the ComfyUI-VibeVoice node running in your environment.
|
||||
|
||||
### Installation
|
||||
The node can be installed via **ComfyUI Manager:** Find `ComfyUI-VibeVoice` and click "Install". Or, install it manually:
|
||||
|
||||
1. **Clone the Repository:**
|
||||
Navigate to your `ComfyUI/custom_nodes/` directory and clone this repository:
|
||||
```sh
|
||||
git clone https://github.com/wildminder/ComfyUI-VibeVoice.git
|
||||
```
|
||||
|
||||
2. **Install Dependencies:**
|
||||
Open a terminal or command prompt, navigate into the cloned directory, and install the required Python packages. **For quantization support, ensure you install `bitsandbytes`**.
|
||||
```sh
|
||||
cd ComfyUI-VibeVoice
|
||||
pip install -r requirements.txt
|
||||
```
|
||||
|
||||
3. **Start/Restart ComfyUI:**
|
||||
Launch ComfyUI. The "VibeVoice TTS" node will appear under the `audio/tts` category. The first time you use the node, it will automatically download the selected model to your `ComfyUI/models/tts/VibeVoice/` folder.
|
||||
|
||||
## Models
|
||||
| Model | Context Length | Generation Length | Weight |
|
||||
|-------|----------------|----------|----------|
|
||||
| VibeVoice-1.5B | 64K | ~90 min | [HF link](https://huggingface.co/microsoft/VibeVoice-1.5B) |
|
||||
| VibeVoice-Large| 32K | ~45 min | [HF link](https://huggingface.co/microsoft/VibeVoice-Large) |
|
||||
|
||||
<p align="right">(<a href="#readme-top">back to top</a>)</p>
|
||||
|
||||
<!-- USAGE EXAMPLES -->
|
||||
## Usage
|
||||
|
||||
The node is designed to be intuitive within the ComfyUI workflow.
|
||||
|
||||
1. **Add Nodes:** Add the `VibeVoice TTS` node to your graph. Use ComfyUI's built-in `Load Audio` node to load your reference voice files.
|
||||
2. **Connect Voices:** Connect the `AUDIO` output from each `Load Audio` node to the corresponding `speaker_*_voice` input on the VibeVoice TTS node.
|
||||
3. **Write Script:** In the `text` input, write your dialogue. Assign lines to speakers using the format `Speaker 1: ...`, `Speaker 2: ...`, etc., on separate lines.
|
||||
4. **Generate:** Queue the prompt. The node will process the script and generate a single audio file containing the full conversation.
|
||||
|
||||
_For a complete workflow, you can drag the example image from the `example_workflows` folder onto your ComfyUI canvas._
|
||||
|
||||
### Node Inputs
|
||||
|
||||
* **`model_name`**: Select the VibeVoice model to use.
|
||||
* **`quantize_llm`**: (New!) Enable to run the LLM component in 4-bit (NF4) mode. This dramatically reduces VRAM and can significantly speed up inference on the 7B model.
|
||||
* **`text`**: The conversational script. Lines must be prefixed with `Speaker <number>:` (e.g., `Speaker 1:`).
|
||||
* **`cfg_scale`**: Controls how strongly the model adheres to the reference voice's timbre.
|
||||
* **`inference_steps`**: Number of diffusion steps for the audio decoder.
|
||||
* **`seed`**: A seed for reproducibility.
|
||||
* **`do_sample`, `temperature`, `top_p`, `top_k`**: Standard sampling parameters for controlling the creativity and determinism of the speech generation.
|
||||
* **`force_offload`**: (New!) Forces the model to be completely offloaded from VRAM after generation. Useful for memory management but may slow down subsequent runs.
|
||||
* **`speaker_*_voice` (Optional)**: Connect an `AUDIO` output from a `Load Audio` node to provide a voice reference.
|
||||
|
||||
### Performance & Quantization
|
||||
|
||||
A key feature of this node is the optional **4-bit quantization** for the language model component. This is highly recommended for users with memory-constrained GPUs (e.g., <= 16GB VRAM) who wish to run the larger `VibeVoice-Large-pt` model.
|
||||
|
||||
**Benefits of `quantize_llm = Enabled`:**
|
||||
|
||||
| Model | Performance Impact | VRAM Savings |
|
||||
|---|---|---|
|
||||
| **VibeVoice-Large (7B)** | **~8.5x faster** inference | Saves **>4.4 GB** (over 36%) |
|
||||
| **VibeVoice-1.5B** | ~1.5x slower inference | Saves **~5.5 GB** (over 63%) |
|
||||
|
||||
As shown, quantization provides a massive speedup and VRAM reduction for the 7B model, making it accessible on a wider range of hardware. While it slightly slows down the 1.5B model, the significant VRAM savings may still be beneficial for complex workflows.
|
||||
|
||||
### Transformers Library Compatibility
|
||||
|
||||
This version includes automatic detection and compatibility for both older and newer versions of the Transformers library:
|
||||
|
||||
* **Transformers 4.56+**: Automatically uses the new method signature for `_prepare_cache_for_generation`
|
||||
* **Older Versions**: Maintains compatibility with pre-4.56 versions using the legacy method signature
|
||||
* **Fallback Mechanism**: If detection fails, the node will automatically try both versions to ensure maximum compatibility
|
||||
|
||||
This ensures the node works seamlessly regardless of your Transformers version without requiring manual updates.
|
||||
|
||||
### Tips from the Original Authors
|
||||
|
||||
* **Punctuation:** For Chinese text, using English punctuation (commas and periods) can improve stability.
|
||||
* **Model Choice:** The 7B model variant (`VibeVoice-Large`) is generally more stable.
|
||||
* **Spontaneous Sounds/Music:** The model may spontaneously generate background music, especially if the reference audio contains it or if the text includes introductory phrases like "Welcome to...". This is an emergent capability and cannot be directly controlled.
|
||||
* **Singing:** The model was not trained on singing data, but it may attempt to sing as an emergent behavior. Results may vary.

<!-- BUG FIXES -->
|
||||
## Recent Bug Fixes
|
||||
|
||||
### Force Offload Compatibility Fix
|
||||
* **Fixed:** Resolved `AttributeError: module 'comfy.model_management' has no attribute 'unload_model_clones'` error when using the force offload option
|
||||
* **Details:** Updated the force offload implementation to use ComfyUI's standard `unload_all_models()` API instead of the deprecated `unload_model_clones()` function
|
||||
* **Impact:** Force offload functionality now works correctly with all versions of ComfyUI
|
||||
|
||||
### Multi-Speaker DynamicCache Fix
|
||||
* **Fixed:** Resolved `'DynamicCache' object has no attribute 'key_cache'` error when using multiple speakers
|
||||
* **Details:** Updated cache access in `modeling_vibevoice_inference.py` to use proper DynamicCache API - accessing layers via indexing instead of deprecated `.key_cache` and `.value_cache` attributes
|
||||
* **Impact:** Multi-speaker functionality now works correctly with newer versions of Transformers library
