🎙️ Higgs_v3-TTS-ComfyUI - Create Multilingual Speech With Precise Control

Higgs_v3-TTS-ComfyUI lets you generate speech from text within the ComfyUI workspace. This tool supports 100 languages and creates realistic voices. You can clone voices, add emotions, and include sound effects using simple text tags. The system manages memory so you can generate long audio files without errors.

🛠️ System Requirements

You need a computer that meets these specs to run the software.

• Operating System: Windows 10 or 11 (64-bit).
• Graphics Card: NVIDIA GPU with at least 8GB of VRAM (RTX 3060 or better recommended).
• System Memory: 16GB of RAM or more.
• Storage: At least 10GB of free space on an SSD.
• Software: ComfyUI installed and running on your computer.

📥 Install and Setup

Follow these steps to add these tools to your ComfyUI workspace.

1. Visit the official releases page to download the latest version.
2. Locate the Source code (zip) file from the latest release list.
3. Right-click the zip file and choose Extract All to unzip the files.
4. Copy the extracted folder into your /ComfyUI/custom_nodes/ directory.
5. Restart ComfyUI to load the nodes.

🧱 Understanding the Nodes

This tool introduces several custom nodes to your interface. Each node handles a specific part of the speech creation process.

Higgs Loader

Use this node to load the voice model. It selects the specific language and voice profile you want to use. You must connect this to the main generator block.

Higgs Generation

This acts as the core engine. Input your text here. You can include tags to change how the voice sounds. For example, use tags like [angry] or [whisper] inside your bracketed text to adjust emotion.

Memory Manager

This node keeps your computer from overheating or running out of memory. It processes long text blocks in sections. Keep this node connected if you generate long dialogue or stories.

🎯 Creating Your First Voice

Follow this workflow to create your first audio file.

1. Open ComfyUI.
2. Right-click the grid and select Add Node.
3. Browse for Higgs nodes in the menu.
4. Place the Higgs Loader and the Higgs Generator nodes.
5. Link the Loader output to the Generator input.
6. Type a sentence in the text box.
7. Click Queue Prompt.

Wait for the process bar to finish. Your audio will appear in the playback window once completed.

🗣️ Voice Cloning Guide

You can copy a specific voice from an audio file.

1. Prepare a clear audio clip of the person you want to copy.
2. Add the Voice Cloning node to your workspace.
3. Upload your audio clip.
4. Connect the cloned voice output to your Higgs Generator.
5. The system now uses the traits of your uploaded clip for all new speech.

Keep your source audio clear and loud for the best results. Background noise often makes the clone sound grainy.

⚙️ Handling Long Audio

Generating long dialogue takes more memory than a single sentence. Use the Chunking settings to split your text.

• Chunk Size: Determines how many characters the system processes at once.
• Overlap: Keeps the tone consistent between different audio pieces.

If you get a memory error, reduce the chunk size. This forces the system to process less data in each step.

🧪 Common Issues

Most errors happen because of your graphics card. If the process stops mid-way, check these items.

• VRAM Usage: Close other programs like web browsers or video games while you use ComfyUI.
• Path Names: Avoid using folders with special symbols or non-English characters in your file paths. Use simple folder names like C:/ComfyUI.
• Node Updates: Check the release page often. We update these nodes to work with the latest ComfyUI builds. If the nodes turn red, you might need to update your ComfyUI environment.

💡 Pro Tips

• Emotion Tags: Combine tags for unique effects. Using [happy] and [whisper] together creates a soft, cheerful tone.
• SFX: Add sound effect tags to trigger specific background noises in your dialogue scenes.
• Dialogue: Use the Multi-speaker node to assign different voices to different names. Link each name tag in your text to their respective voice profile.
• Punctuation: Use commas and periods to time your speech. The system pauses based on your grammar. Long pauses require multiple dots.

This environment provides complete control over your audio projects. Start with short sentences and add complexity as you learn how the tags change the output.
