Getting Started: Installation Made Easy

There are two ways to install the ComfyUI-ChatTTS extension: using the ComfyUI Manager or manually. Here's a quick walkthrough for both:

Method 1: Using ComfyUI Manager (Recommended)

• Install the ComfyUI Manager if you haven't already.
• Open ComfyUI Manager and search for "ChatTTS."
• Click "Install" next to the ComfyUI-ChatTTS extension.

Method 2: Manual Installation

• Navigate to your ComfyUI's custom_nodes directory.
• Clone the repository using: git clone https://github.com/neverbiasu/ComfyUI-ChatTTS
• Install the necessary requirements:
  • cd ComfyUI-ChatTTS
  • pip install -r requirements.txt

Model Setup: Automatic Downloads or Manual Placement

The ChatTTS models are crucial for generating speech.

• The first time you use the ChatTTSLoader node, the extension will automatically:
  • Check for existing models in the models/chattts directory.
  • Download the models from the official repository if none are found.
  • Load the model for immediate use in your workflow.
• Alternatively, you can manually place the models in the models/chattts directory.

Basic Text-to-Speech Workflow: Your First Project

Let's break down a simple workflow to get you started with ComfyUI-ChatTTS.

1. Load the ChatTTS Model: Use the ChatTTSLoader node to load your desired model. This node handles the model loading and management.
2. Sample a Random Speaker Voice: Utilize the voice sampling feature to choose a voice. This adds variety and customization to your speech generation.
3. Convert Text to Speech: Input your text into the appropriate node (e.g., a text input node connected to the ChatTTS node) to convert it into speech.
4. Preview the Audio Output: Use ComfyUI's audio preview nodes to listen to your generated speech. This allows for quick iteration and refinement.

Fine-Tuning Your Speech: Control Tags and Customization

ChatTTS supports special tags that allow you to control speech generation without altering model parameters. These tags let you customize aspects like pronunciation, pauses, and emphasis. Experiment with these tags to achieve the perfect voice for your needs.

Real-World Applications: Where Can You Use ComfyUI-ChatTTS?

The possibilities are endless:

• Voiceovers for Animations: Create custom voiceovers for your animated projects using unique voices.
• Interactive Storytelling: Dynamically generate character dialogue in interactive narratives.
• Accessibility Tools: Convert text into audio for users with visual impairments.
• Prototyping Dialogue: Quickly prototype and iterate on dialogue for games and applications.
• Content Creation: Produce high-quality audio content for podcasts, videos, and more.

The integration of text-to-speech within ComfyUI simplifies the process of adding spoken elements to visual creations, making projects more engaging and accessible.
