ComfyUI Extension: ComfyUI-KaniTTS

ComfyUI-KaniTTS Introduction

ComfyUI-KaniTTS is an innovative extension designed to integrate the KaniTTS family of Text-to-Speech (TTS) models into the ComfyUI platform. This extension is tailored for AI artists who wish to transform text into high-quality speech effortlessly. By leveraging the power of KaniTTS, ComfyUI-KaniTTS offers a seamless way to generate speech with remarkable speed and fidelity, making it ideal for real-time applications. Whether you're creating voiceovers for digital art, animations, or interactive media, this extension provides a versatile toolset to bring your text to life with a variety of voices and languages.

How ComfyUI-KaniTTS Works

At its core, ComfyUI-KaniTTS operates using a two-stage pipeline. First, it employs a sophisticated language model to interpret and process the input text. Then, it utilizes an efficient audio codec to convert this processed text into speech. This approach ensures that the generated audio is not only fast but also of high quality. Imagine it as a skilled translator who not only understands the nuances of language but also has the ability to deliver it with the right tone and clarity. This makes ComfyUI-KaniTTS a powerful tool for artists looking to add a vocal dimension to their projects.

ComfyUI-KaniTTS Features

ComfyUI-KaniTTS is packed with features that enhance its usability and flexibility:

• Multi-Speaker Synthesis: With the kani-tts-370m model, you can choose from a diverse array of predefined voices across multiple languages, allowing for a rich variety of vocal expressions.
• Variety of Models: The extension provides access to five different KaniTTS models, each catering to different needs, from creative voice generation to specific vocal characteristics.
• Automatic Model Management: The extension automatically handles the downloading and management of KaniTTS and NeMo codec models, optimizing memory usage to save VRAM.
• Fine-Grained Control: Users can adjust parameters such as temperature, top-p, and repetition penalty to fine-tune the style and performance of the generated speech.
• High-Efficiency Synthesis: Designed for low-latency inference, ComfyUI-KaniTTS can generate 15 seconds of audio in under a second on modern GPUs, making it suitable for real-time applications.

ComfyUI-KaniTTS Models

ComfyUI-KaniTTS offers a selection of models, each with unique capabilities:

• kani-tts-370m: A multi-speaker model supporting a wide range of voices in various languages. Ideal for projects requiring diverse vocal expressions.
• kani-tts-450m-0.1-pt: A base model pretrained on English, suitable for generating generic or randomized voices.
• kani-tts-450m-0.1-ft: A finetuned model producing a consistent male voice, perfect for projects needing a specific male vocal character.
• kani-tts-450m-0.2-pt: Another base model with broader multilingual support, offering creative voice generation.
• kani-tts-450m-0.2-ft: A finetuned model for a consistent female voice, ideal for projects requiring a specific female vocal character.

Troubleshooting ComfyUI-KaniTTS

If you encounter issues while using ComfyUI-KaniTTS, here are some common problems and solutions:

• Model Download Issues: Ensure you have a stable internet connection. If a model fails to download, try restarting ComfyUI.
• Audio Quality Concerns: Adjust the temperature and top-p settings to refine the speech output. Lowering the temperature can result in more coherent speech.
• Performance Issues: If you experience lag, consider reducing the input text length or adjusting the max_new_tokens parameter.
• Installation Problems on Windows: Manually install pre-built packages for dependencies like nemo_toolkit using the provided .whl files.
