ComfyUI Node: Kokoro Speaker Combiner

Kokoro Speaker Combiner:

The KokoroSpeakerCombiner is a specialized node designed to blend two distinct speaker profiles into a single, cohesive voice style. This node is particularly useful for AI artists and developers who wish to create unique voice outputs by combining characteristics from two different speakers. By adjusting the weight parameter, you can control the influence each speaker has on the final output, allowing for a seamless transition between the two voices. This capability is essential for generating diverse and personalized audio content, enhancing the creative possibilities in voice synthesis projects.

Kokoro Speaker Combiner Input Parameters:

speaker_a

speaker_a is the first speaker profile to be combined. It represents one of the two voices that will contribute to the final synthesized voice. This parameter is crucial as it provides the initial set of voice characteristics that will be blended with those of speaker_b.

speaker_b

speaker_b is the second speaker profile involved in the combination process. Like speaker_a, it contributes its unique voice characteristics to the final output. The combination of speaker_a and speaker_b allows for the creation of a new, hybrid voice style.

weight

The weight parameter determines the proportion of influence each speaker has on the final voice output. It is a floating-point value ranging from 0 to 1, with a default value of 0.5. A weight closer to 0 gives more influence to speaker_b, while a weight closer to 1 favors speaker_a. This parameter allows for fine-tuning the balance between the two voices, enabling precise control over the resulting voice style.

Kokoro Speaker Combiner Output Parameters:

speaker

The output parameter speaker is a combined speaker profile that results from blending speaker_a and speaker_b according to the specified weight. This output is a new KOKORO_SPEAKER object that encapsulates the characteristics of both input speakers, providing a unique voice style that can be used in further audio synthesis tasks.

Kokoro Speaker Combiner Usage Tips:

• Experiment with different weight values to achieve the desired balance between the two speakers. A weight of 0.5 provides an equal blend, while adjusting towards 0 or 1 will favor one speaker over the other.
• Use the KokoroSpeakerCombiner to create subtle variations in voice styles by slightly altering the weight parameter, which can be particularly useful in projects requiring multiple similar yet distinct voices.

Kokoro Speaker Combiner 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 voice files are correctly downloaded and located in the specified directory. If necessary, re-download the files using the provided URLs.

"no audio is generated"

• Explanation: This error indicates that the audio generation process failed, possibly due to incorrect input parameters or issues with the model.
• Solution: Verify that all input parameters are correctly set and that the model files are intact. Check for any additional error messages that might provide more context on the issue.
