ComfyUI_Spark_TTS

A custom node package for ComfyUI that integrates the powerful Spark-TTS text-to-speech model. This package provides nodes for controllable speech synthesis and voice cloning, built upon the core logic of the official Spark-TTS library.

---

---

Nodes

• Spark_TTS_Creation: Controllably generates speech with specific gender, pitch, and speed.
• Spark_TTS_Clone: Synthesizes speech by cloning a voice from a reference audio (custom uploaded or preset).

Node Descriptions

1. Spark_TTS_Creation (Voice Creation)

• Function: Input text, select parameters like gender, pitch, and speed to generate customized speech.
• Key Inputs:
  • text: The text to be converted to speech.
  • gender: Choose "female" or "male".
  • pitch: Select pitch level (from "very_low" to "very_high").
  • speed: Select speed level (from "very_low" to "very_high").
  • temperature, top_k, top_p, max_new_tokens: Adjust the diversity and length of the generated speech.
  • keep_model_loaded: Choose whether to keep the model in memory after generation (True keeps it, faster; False unloads it, saves VRAM).
• Outputs:
  • Audio: The generated audio.
  • Node Status: Displays the running status or error messages.
• Usage: Fill in the text, adjust parameters, and generate speech.

2. Spark_TTS_Clone (Voice Cloning)

• Function: Input text and provide a reference audio; the node will attempt to read the text using the timbre of the reference audio.
• Key Inputs:
  • text: The text to be read with the cloned timbre.
  • custom_prompt_text: (Optional) The transcript corresponding to the reference audio, helps improve cloning quality.
  • speaker_preset: Select a speaker from a preset list as the reference voice (ignored if Audio_reference is connected).
  • Audio_reference: (Optional) Connect an external audio source as the reference for voice cloning (e.g., output of a "Load Audio" node). This takes precedence over speaker_preset.
  • pitch, speed: (Optional) Adjust the pitch and speed of the output voice, mainly effective when the cloning signal is not strong or for future features.
  • temperature, top_k, top_p, max_new_tokens: Adjust the diversity and length of the generated speech.
  • keep_model_loaded: Choose whether to keep the model in memory after generation.
• Outputs:
  • Audio: The generated cloned speech.
  • Node Status: Displays the running status or error messages.
• Usage: Fill in the text. Either connect an Audio_reference (recommended to also provide custom_prompt_text) OR select a preset voice from speaker_preset. Then run.

Installation Steps

1. Navigate to ComfyUI custom_nodes directory:

   cd path/to/your/ComfyUI/custom_nodes
   

2. Clone this repository:

   git clone https://github.com/KERRY-YUAN/ComfyUI_Spark_TTS ComfyUI_Spark_TTS
   cd ComfyUI_Spark_TTS
   

3. Install Dependencies: Install the required Python libraries using your ComfyUI Python environment.

   # Example for ComfyUI's embedded Python on Windows:
   # path/to/your/ComfyUI/python_embeded/python.exe -m pip install -r requirements.txt
   # 
   # Or for a system-wide/venv Python:
   pip install -r requirements.txt
   

   Note: Ensure torch and torchaudio versions are compatible with your system and ComfyUI's existing PyTorch installation. The versions listed are from the original Spark-TTS requirements.txt.

📥 Model and Data Setup

The Spark-TTS model and Speaker Preset data must be placed in specific default locations for the nodes to function correctly. The node will attempt to automatically download any missing models/data when it's first used in a workflow.

If the automatic download fails, or if you prefer to download them manually beforehand, you can run the Model_Download.bat script located in the ComfyUI_Spark_TTS custom node directory.

1. Default Spark-TTS 0.5B Model Location: ComfyUI/models/TTS/Spark-TTS/Spark-TTS-0.5B/ (Downloaded from Hugging Face SparkAudio/Spark-TTS-0.5B)

2. Default Speaker Preset Files Location: ComfyUI/models/TTS/Speaker_Preset/ (Cloned from GitHub KERRY-YUAN/Speaker_Preset)

3. Using Model_Download.bat: Navigate to your ComfyUI/custom_nodes/ComfyUI_Spark_TTS/ directory and run:

   .\Model_Download.bat
   

   This script requires Git to be installed and accessible in your system's PATH. It will also attempt to install Python packages like gdown, huggingface_hub, and GitPython if they are missing, using the Python environment it detects for ComfyUI (or system Python as a fallback).

4. Directory Structure Reference (After Download): The required final file structure is:

   ComfyUI/
   ├── custom_nodes/
   │   └── ComfyUI_Spark_TTS/
   │       ├── model_download/
   │       │   ├── model_download.py
   │       │   └── model_list.json
   │       ├── sparktts/             
   │       ├── NodeSparkTTS.py
   │       ├── Model_Download.bat  <-- Run this script for manual/troubleshooting
   │       └── ... (other package files)
   └── models/
       └── TTS/
           ├── Spark-TTS/
           │   └── Spark-TTS-0.5B/    <-- Spark-TTS model folder
           └── Speaker_Preset/        <-- Speaker Preset folder
               ├── speakers_info.json 
               └── ...                
   

   • The speakers_info.json file within the Speaker_Preset folder maps speaker names to their prompt texts.
   • Prompt audio files should be named {SpeakerName}_prompt.{extension}.
   • The sparktts folder within the ComfyUI_Spark_TTS node package is copied from the official Spark-TTS repository. All its subdirectories should contain an __init__.py file to be recognized as Python packages.
   • The speakers_info.json file folder maps speaker names (for the dropdown in the Spark_TTS_Clone node) to their corresponding prompt texts, which you can add to or modify. Example:

     {
         "Alice": "This is the reference text for Alice's voice.",
         "Bob_enthusiastic": "Hello there! I am Bob, and I sound very excited!"
     }
     

   • Prompt audio files should be named {SpeakerName}_prompt.{extension} (e.g., Alice_prompt.wav).

   注意：请确保 torch 和 torchaudio 版本与您的系统以及 ComfyUI 现有的 PyTorch 安装兼容。所列版本来自原始 Spark-TTS 的 requirements.txt。

📥 模型和数据设置

Spark-TTS 模型和说话人预设数据 必须放置在特定的默认位置，节点才能正常工作。当节点在工作流中首次使用时，它会尝试自动下载任何缺失的模型/数据。

如果自动下载失败，或者您希望预先手动下载它们，可以运行位于 ComfyUI_Spark_TTS 自定义节点目录中的 Model_Download.bat 脚本。

1. 默认 Spark-TTS 0.5B 模型位置： ComfyUI/models/TTS/Spark-TTS/Spark-TTS-0.5B/ （从 Hugging Face SparkAudio/Spark-TTS-0.5B 下载）

2. 默认说话人预设文件位置： ComfyUI/models/TTS/Speaker_Preset/ （从 GitHub KERRY-YUAN/Speaker_Preset 克隆）

3. 使用 Model_Download.bat： 导航到您的 ComfyUI/custom_nodes/ComfyUI_Spark_TTS/ 目录并运行：

   .\Model_Download.bat
   

   此脚本需要您的系统中安装了 Git 并已将其添加到系统的 PATH 环境变量中。它还会尝试安装 Python 包如 gdown、huggingface_hub 和 GitPython（如果缺失），使用的是它为 ComfyUI 检测到的 Python 环境（或系统 Python 作为备选）。

4. 目录结构参考（下载后）： 必需的最终文件架构如下：

   ComfyUI/
   ├── custom_nodes/
   │   └── ComfyUI_Spark_TTS/
   │       ├── model_download/
   │       │   ├── model_download.py
   │       │   └── model_list.json
   │       ├── sparktts/             
   │       ├── NodeSparkTTS.py
   │       ├── Model_Download.bat  <-- 可运行此脚本进行手动下载/故障排除
   │       └── ... (其他包内文件)
   └── models/
       └── TTS/
           ├── Spark-TTS/
           │   └── Spark-TTS-0.5B/    <-- Spark-TTS 模型文件夹
           └── Speaker_Preset/        <-- Speaker_Preset 文件夹
               ├── speakers_info.json 
               └── ...                
   

   • Speaker_Preset 文件夹内的speakers_info.json 文件将说话人名称映射到其相应的提示文本。
   • 提示音频文件应命名为 {说话人名}_prompt.{扩展名}。
   • ComfyUI_Spark_TTS 节点包内的 sparktts 文件夹为官方 Spark-TTS 仓库复制。其所有子目录应包含一个 __init__.py 文件，以便被识别为 Python 包。
   • speakers_info.json 文件将说话人名称（用于 Spark_TTS_Clone 节点中的下拉列表）映射到其相应的提示文本，可以自行增减。示例：

     {
         "爱丽丝": "这是爱丽丝声音的参考文本。",
         "鲍勃_热情": "你好呀！我是鲍勃，我听起来非常兴奋！"
     }
     

   • 提示音频文件应命名为 {说话人名}_prompt.{扩展名} (例如, 爱丽丝_prompt.wav)。
