ComfyUI Node: Piper Speak Text

Piper Speak Text:

The Piper_Speak_Text node is designed to convert text into speech using a PiperVoice object from the Piper Text-to-Speech (TTS) system. This node is particularly useful for AI artists and developers who want to integrate voice synthesis into their projects, allowing for dynamic and interactive audio experiences. By leveraging the capabilities of the Piper TTS engine, this node can transform written text into audible speech, providing a seamless way to add voice output to applications. The primary function of this node is to synthesize audio from text input, making it an essential tool for creating voiceovers, narrations, or any application requiring text-to-speech conversion.

Piper Speak Text Input Parameters:

TTS

The TTS parameter is a required input that represents the Text-to-Speech engine instance, specifically a PiperVoice object. This parameter is crucial as it dictates the voice characteristics and synthesis capabilities used to convert text into speech. The TTS object must be properly initialized and loaded with a suitable voice model to function correctly. There are no specific minimum, maximum, or default values for this parameter, as it depends on the available TTS models and configurations.

text

The text parameter is a required input that specifies the string of text to be converted into speech. This parameter is essential as it provides the content that the TTS engine will process and vocalize. The text input must be a string, and while there is no explicit minimum or maximum length, excessively long texts may impact performance or require additional handling. The default value is an empty string, but it is mandatory to provide a non-empty string for the node to execute successfully.

Piper Speak Text Output Parameters:

The Piper_Speak_Text node does not produce any direct output parameters. Instead, its primary function is to play the synthesized audio directly through the system's audio output. As such, there are no return values to capture or interpret, as the node's purpose is to audibly render the text input.

Piper Speak Text Usage Tips:

• Ensure that the TTS parameter is correctly initialized with a valid PiperVoice model to avoid errors during execution.
• For optimal performance, consider breaking down long text inputs into smaller segments to ensure smooth and uninterrupted audio playback.

Piper Speak Text Common Errors and Solutions:

Unable to find piper-tts

• Explanation: This error occurs when the Piper TTS library is not installed or not found in the system's Python environment.
• Solution: Ensure that the Piper TTS library is installed in your Python environment. You can try reinstalling it or checking the system path to confirm that the library is accessible.

The model path does not exist

• Explanation: This error indicates that the specified TTS model file could not be found at the given path.
• Solution: Verify that the model file exists at the specified location. If necessary, reload the model or check the path for any typographical errors.
