Higgs Audio v3 Text to Speech ComfyUI workflow for Videcool
The Higgs Audio v3 Text to Speech workflow in Videcool provides a powerful and flexible way to generate natural-sounding speech from text prompts. Designed for speed, clarity, and creative control, this workflow is served by ComfyUI and uses the Higgs Audio v3 AI text-to-speech engine for high-quality speech synthesis.
What can this ComfyUI workflow do?
In short: Text-to-speech synthesis.
This workflow takes a text prompt and synthesizes speech with a natural voice output based on the selected Higgs Audio v3 engine. It interprets your text input and produces clear, high-fidelity audio that is suitable for narration, demos, accessibility, and creative audio production. The base AI model is optimized for chunked text generation and can handle longer passages smoothly using crossfade-based audio stitching.

Image of the ComfyUI workflow
This figure provides a visual overview of the workflow layout inside ComfyUI. Each node is placed in logical order to establish a clean and efficient text-to-speech pipeline. The structure makes it easy to understand how the text input, TTS engine, and audio output nodes interact. Users can modify or expand parts of the workflow to create custom variations or integrate speech generation into larger audio or video production pipelines.
Installation steps
Step 1: Install the Higgs Audio v3 ComfyUI custom node using ComfyUI Manager: Manage custom nodes → Search "Higgs Audio v3" → Install.Step 2: Download the Higgs Audio v3 model files into your ComfyUI model directory used by the custom node.
Step 3: Download the higgs-audio-v3-tts.json workflow file into your home directory.
Step 4: Restart ComfyUI so the custom node and model files are recognized.
Step 5: Open the ComfyUI graphical user interface (ComfyUI GUI).
Step 6: Load the higgs-audio-v3-tts.json workflow in the ComfyUI GUI.
Step 7: Enter the text you want the model to speak in the text input field.
Step 8: Adjust parameters such as temperature, top-p, top-k, chunk size, and silence between chunks if needed.
Step 9: Run the workflow to generate synthesized speech.
Step 10: Open Videcool in your browser and use the generated audio in your video projects.
Installation video
The workflow requires only a text input plus a few basic parameter adjustments to begin generating speech. After loading the JSON file, users can enter the text to be spoken and adjust voice characteristics such as temperature, top-p, top-k, chunk size, and silence between chunks if desired. Once executed, the Higgs Audio v3 engine synthesizes speech, which is then saved as an audio file that can be used across other Videcool tools.
Prerequisites
To run the workflow correctly, download the Higgs Audio v3 model files and install the Higgs Audio v3 custom node. These files ensure the model can process text and synthesize natural-sounding speech. Proper installation into the following locations is essential before running the workflow: {your ComfyUI directory}/models/ and {your ComfyUI directory}/custom_nodes/.
ComfyUI model folder: Higgs Audio v3 model files
Custom Node: Higgs Audio v3 custom node installed via ComfyUI Manager
How to use this workflow in Videcool
Videcool integrates seamlessly with ComfyUI, allowing users to generate speech directly without managing the underlying node graph. After importing the workflow file, simply enter your text and click generate. The system handles all backend interactions with ComfyUI. This makes speech generation intuitive and accessible, even for users who do not want to learn the ComfyUI internals. The following video shows how this model can be used in Videcool:
ComfyUI nodes used
This workflow uses the following nodes. Each node performs a specific role, such as loading text input, running the Higgs Audio v3 engine, and saving the output. Together they create a reliable and modular pipeline that can be easily extended or customized.
Base AI model
This workflow is built on Higgs Audio v3, a modern and highly capable text-to-speech generator. Higgs Audio v3 provides clarity, natural prosody, and voice fidelity, making it suitable for both entertainment and professional use cases. The model benefits from advanced tuning for speech synthesis and offers consistent results across a wide range of text inputs. More details, model weights, and documentation can be found in the project resources.

Speech quality and parameters
Speech quality depends on the input text and the selected generation parameters. For best results, use clean, well-punctuated text and adjust settings only if needed. The workflow supports chunking for longer passages and lets users adjust parameters such as temperature, top-p, top-k, chunk size, silence between chunks, and audio caching to fine-tune the output.
Conclusion
The Higgs Audio v3 Text to Speech ComfyUI workflow is a robust, powerful, and user-friendly solution for generating speech in Videcool. With its combination of a modern TTS engine, a modular ComfyUI pipeline, and seamless platform integration, it enables beginners and professionals alike to produce creative and professional-grade voice content with ease.
