This project integrates the ElevenLabs Text-to-Speech API as a custom node for ComfyUI. It enables seamless text-to-speech conversion directly within ComfyUI, providing the generated audio as a PyTorch tensor for immediate playback or further processing. Ideal for workflows requiring high-quality speech synthesis

    ComfyUI ElevenLabs API integration

    This ComfyUI node adds text-to-speech capabilities using the ElevenLabs API. If you enjoy using it and want to support my work, feel free to buy me a coffee — it’s much appreciated!

    Installation

    Install via the ComfyUI Manager or clone the repo into your custom_nodes folder:

    git clone https://github.com/sysL-padawan/comfyui-elevenlabs-integration.git

    Then change into the directory and install the dependencies:

    pip install -r requirements.txt

    Finally, restart ComfyUI.

    Nodes

    Currently, there is one node for text-to-speech with ElevenLabs.

    ElevenlabsTextToVoice

    • api_key: Your ElevenLabs API key
    • voice_id: The voice ID from ElevenLabs
    • model_id: The desired model (e.g. eleven_multilingual_v2)
    • text: The text to be spoken
    • output_format: Optional, e.g. mp3_44100_128 (default)

    The node returns an audio tensor and the sample rate, which can be used directly for e.g. LipSync.

    Example Workflow

    1. Generate text-to-speech with ElevenLabs.
    2. Use the audio output for LipSync or other audio applications.

    ElevenlabsTextToEffect

    • api_key: Your ElevenLabs API key
    • text: The text to be converted into a sound effect
    • duration: (Optional) Length of the effect in seconds (default: 3, range: 1–22)
    • prompt_influence: (Optional) Influence of the text prompt on the generated effect (default: 0.3, range: 0–1)
    • output_format: (Optional) e.g. mp3_44100_128 (default)

    The node returns an audio tensor and the sample rate, which can be used directly for further audio applications.

    Example Workflow

    1. Generate a sound effect from text with ElevenLabs.
    2. Use the audio output for sound design, effects, or other audio applications.
