ComfyUI Extension: ComfyUI-FishSpeech

ComfyUI-FishSpeech Introduction

ComfyUI-FishSpeech is an extension for the ComfyUI platform that integrates the Fish-Speech model, a powerful tool for generating high-quality speech from text. This extension allows AI artists to easily convert written text into natural-sounding speech, making it an invaluable tool for creating voiceovers, audiobooks, and other audio content. By leveraging the capabilities of Fish-Speech, ComfyUI-FishSpeech helps solve the problem of generating realistic and expressive speech, which can be a challenging task for many AI artists.

How ComfyUI-FishSpeech Works

ComfyUI-FishSpeech works by utilizing the Fish-Speech model, which is a sophisticated text-to-speech (TTS) system. The model takes input text and processes it through a series of neural networks to generate speech. Here's a simplified breakdown of the process:

1. Text Input: You provide the text that you want to convert into speech.
2. Text Processing: The text is processed to understand the context and pronunciation.
3. Speech Synthesis: The processed text is then passed through the Fish-Speech model, which generates the corresponding speech waveform.
4. Output: The generated speech is output as an audio file that you can use in your projects. Think of it like a highly advanced version of a text-to-speech engine, but with much more natural and expressive results.

ComfyUI-FishSpeech Features

ComfyUI-FishSpeech comes with several features designed to enhance your experience and provide flexibility in generating speech:

• High-Quality Speech Generation: Produces natural and expressive speech that sounds like a real human voice.
• Customizable Voice Settings: Allows you to adjust various parameters such as pitch, speed, and tone to create the desired voice effect.
• Multi-Language Support: Supports multiple languages, making it versatile for different linguistic needs.
• Easy Integration: Seamlessly integrates with ComfyUI, allowing you to use it within your existing workflow without any hassle.

Customization Examples

• Pitch Adjustment: Lowering the pitch can make the voice sound deeper, while raising it can make it sound higher.
• Speed Control: Slowing down the speech can make it more dramatic, while speeding it up can make it more energetic.
• Tone Variation: Adjusting the tone can help convey different emotions, such as happiness, sadness, or excitement.

ComfyUI-FishSpeech Models

ComfyUI-FishSpeech utilizes the Fish-Speech model, which is designed to generate high-quality speech. The model is pre-trained and optimized for various speech synthesis tasks. Here are some key aspects of the model:

• VITS2: A variant of the VITS model, known for its high-quality and natural-sounding speech.
• Bert-VITS2: Combines the capabilities of BERT and VITS2 for enhanced text understanding and speech generation.
• GPT VITS: Integrates GPT for improved contextual understanding and more expressive speech.

When to Use Each Model

• VITS2: Use this model for general-purpose speech synthesis where high quality is required.
• Bert-VITS2: Ideal for complex texts that require better contextual understanding.
• GPT VITS: Best for generating speech with expressive and nuanced intonation.

Troubleshooting ComfyUI-FishSpeech

Here are some common issues you might encounter while using ComfyUI-FishSpeech and how to resolve them:

Common Issues and Solutions

1. FFmpeg Not Working:

• Solution: Ensure that FFmpeg is installed and accessible from the command line. For Linux, use apt update and apt install ffmpeg. For Windows, you can install FFmpeg using .

2. Installation Errors:

• Solution: If you encounter errors during installation, such as issues with samplerate, try running pip -q install git+https://github.com/tuxu/python-samplerate.git@fix_cmake_dep.

3. Torch Import Error:

• Solution: If you see an error like "cannot import name 'weight_norm' from 'torch.nn.utils.parametrizations'", update your Torch library to the latest version.

Frequently Asked Questions

• Q: How do I update the Fish-Speech model?
• A: The model weights are automatically downloaded from Hugging Face. Ensure your internet connection is stable, especially if you are in China, where you might need to configure a mirror.
