ComfyUI Node: Kokoro Speaker

Kokoro Speaker:

The KokoroSpeaker node is designed to facilitate the selection and utilization of pre-defined speaker voices within the Kokoro text-to-speech system. This node allows you to choose from a variety of speaker profiles, each with unique voice characteristics, to generate synthetic speech. The primary goal of the KokoroSpeaker node is to provide a straightforward interface for selecting a speaker's voice, which can then be used in conjunction with other nodes to produce audio outputs. By offering a range of speaker options, this node enhances the flexibility and creativity of AI artists, enabling them to tailor the voice output to suit different artistic needs and projects.

Kokoro Speaker Input Parameters:

speaker_name

The speaker_name parameter allows you to select a specific speaker profile from a predefined list of options. Each speaker profile represents a unique voice style, which can significantly impact the tone and character of the generated speech. The available options include voices such as "af_sarah", "af_bella", "am_adam", and others, each offering distinct vocal qualities. The default value is "af_sarah", providing a starting point for users. This parameter is crucial for defining the voice characteristics of the output audio, allowing you to match the voice to the desired emotional or narrative context of your project.

Kokoro Speaker Output Parameters:

speaker

The speaker output parameter provides a data structure containing the selected speaker's voice characteristics. This output is essential for subsequent nodes that require a speaker input to generate audio. The speaker parameter encapsulates the voice style information, ensuring that the chosen voice is consistently applied in the text-to-speech generation process. This output is a key component in creating coherent and contextually appropriate audio outputs, as it carries the specific voice attributes needed for synthesis.

Kokoro Speaker Usage Tips:

• Experiment with different speaker_name options to find the voice that best fits the mood or theme of your project. Each speaker has unique vocal qualities that can enhance the emotional impact of your audio.
• Use the KokoroSpeaker node in combination with other nodes like KokoroGenerator to create a complete text-to-speech pipeline. This allows for seamless integration of voice selection and audio generation.

Kokoro Speaker Common Errors and Solutions:

ERROR: could not load kokoro-onnx in generate

• Explanation: This error occurs when the Kokoro model files are not properly loaded, possibly due to missing or corrupted files.
• Solution: Ensure that the model and voices files are correctly downloaded and located in the specified directory. You may need to re-download the files if they are missing or corrupted.

no audio is generated

• Explanation: This error indicates that the audio generation process failed, possibly due to incorrect input parameters or issues with the Kokoro model.
• Solution: Verify that all input parameters are correctly set and that the Kokoro model is properly loaded. Check for any issues in the input text or speaker selection that might affect audio generation.
