ComfyUI Node: IndexTTS Run

IndexTTS Run:

The IndexTTSRun node is designed to facilitate text-to-speech (TTS) conversion using advanced machine learning models. It leverages a combination of audio prompts and textual input to generate speech outputs that are both natural and contextually relevant. This node is particularly beneficial for applications requiring high-quality voice synthesis, such as virtual assistants, audiobooks, and interactive media. By integrating sophisticated models like GPT and BigVGAN, IndexTTSRun ensures that the generated speech is not only accurate in terms of pronunciation and intonation but also adaptable to different languages and dialects. The node's primary goal is to provide a seamless and efficient TTS solution that can be easily integrated into various AI-driven projects, enhancing user interaction through realistic voice outputs.

IndexTTS Run Input Parameters:

version

The version parameter specifies the version of the TTS model to be used. It offers options such as "v1.5" and "V1.0", with "v1.5" being the default. This parameter impacts the model's performance and the quality of the generated speech, as different versions may have varying levels of optimization and feature sets.

audio_prompt

The audio_prompt parameter is an audio input that serves as a reference for the TTS process. It is expected to be in the form of an audio waveform, which helps in conditioning the model to produce speech that matches the desired tone and style. This parameter is crucial for achieving a natural and coherent speech output.

text

The text parameter is a string input that represents the textual content to be converted into speech. It is a required field and must be provided by the user. The text input directly influences the content of the generated speech, and its quality can affect the clarity and accuracy of the TTS output.

IndexTTS Run Output Parameters:

wavs

The wavs output parameter contains the generated audio waveform(s) resulting from the TTS process. This output is crucial as it represents the final speech synthesis, which can be used in various applications such as voiceovers, virtual assistants, and more. The quality and naturalness of the wavs output are directly influenced by the input parameters and the model version used.

IndexTTS Run Usage Tips:

• Ensure that the audio_prompt is clear and of high quality to achieve the best results in speech synthesis.
• Experiment with different version options to find the model that best suits your specific needs in terms of voice quality and performance.

IndexTTS Run Common Errors and Solutions:

"Audio prompt not found"

• Explanation: This error occurs when the audio_prompt parameter is not provided or is incorrectly formatted.
• Solution: Verify that the audio_prompt is correctly specified and that the audio file is accessible and in the correct format.

"Text input is required"

• Explanation: This error indicates that the text parameter is missing, which is essential for the TTS process.
• Solution: Ensure that you provide a valid string input for the text parameter before executing the node.
