ComfyUI Node: 📝➜🔊 TTS - Text to Speech

📝➜🔊 TTS - Text to Speech:

The Bjornulf_TextToSpeech node is designed to convert written text into spoken audio, providing a seamless way to generate speech from text inputs. This node is particularly beneficial for applications that require auditory output, such as voiceovers, accessibility tools, and interactive voice response systems. By leveraging this node, you can transform text into audio in various languages, with the option to select different speakers and customize the output. The node ensures flexibility by allowing you to save the generated audio, choose whether to overwrite existing files, and even play the audio automatically. Its primary goal is to facilitate the creation of high-quality speech from text, making it an essential tool for AI artists and developers looking to integrate text-to-speech capabilities into their projects.

📝➜🔊 TTS - Text to Speech Input Parameters:

text

The text parameter is the core input for the node, representing the written content you wish to convert into speech. It directly influences the audio output, as the text provided will be spoken in the generated audio file. There are no specific minimum or maximum values for this parameter, but it is advisable to keep the text concise for clarity in speech.

language

The language parameter determines the language in which the text will be spoken. It affects the pronunciation and intonation of the generated speech. The node supports multiple languages, and you can select from options like English, Spanish, French, and more. The default value is typically set to English.

autoplay

The autoplay parameter is a boolean option that, when enabled, automatically plays the generated audio after it is created. This feature is useful for immediate feedback and testing purposes. The default value is usually set to False.

seed

The seed parameter is used to ensure consistency in the audio generation process. By setting a specific seed value, you can reproduce the same audio output for the same text input, which is useful for testing and debugging. There are no strict minimum or maximum values, but it should be an integer.

save_audio

The save_audio parameter is a boolean option that determines whether the generated audio should be saved to a file. Enabling this option allows you to keep a permanent copy of the audio for future use. The default value is typically True.

overwrite

The overwrite parameter is a boolean option that controls whether existing audio files should be overwritten. If set to True, any existing file with the same name will be replaced by the new audio. The default value is usually False.

speaker_wav

The speaker_wav parameter specifies the speaker's voice to be used for the text-to-speech conversion. You can choose a specific speaker file or use the default option for the selected language. This parameter impacts the voice characteristics of the generated audio.

connect_to_workflow

The connect_to_workflow parameter is an optional input that allows integration with other nodes or workflows. It is used to connect the text-to-speech process with other components in a larger system, enhancing automation and functionality.

📝➜🔊 TTS - Text to Speech Output Parameters:

audio_output

The audio_output parameter is the primary output of the node, containing the generated audio data. This output is crucial as it represents the spoken version of the input text, ready for playback or further processing.

save_path

The save_path parameter provides the relative path where the audio file is saved. It is important for locating the generated audio file within the system, especially when save_audio is enabled.

full_path

The full_path parameter gives the absolute path to the saved audio file. This output is essential for accessing the audio file directly from the file system, ensuring easy retrieval and management.

duration

The duration parameter indicates the length of the generated audio in seconds. It is useful for understanding the time span of the audio output, which can be important for synchronization and timing purposes.

📝➜🔊 TTS - Text to Speech Usage Tips:

• Ensure the text input is clear and concise to improve the quality of the generated speech.
• Use the language parameter to match the text's language for accurate pronunciation.
• Set the seed parameter to a fixed value for consistent audio outputs during testing.
• Enable autoplay for quick feedback when testing different text inputs.
• Use save_audio and overwrite wisely to manage file storage and avoid unintentional data loss.

📝➜🔊 TTS - Text to Speech Common Errors and Solutions:

Error: No WAV files available for text-to-speech.

• Explanation: This error occurs when there are no available speaker WAV files for the selected language.
• Solution: Ensure that the speaker WAV files are correctly placed in the designated directory and that the speaker_wav parameter is set correctly.

Error: Error generating audio: <error_message>

• Explanation: This error indicates a problem occurred during the audio generation process, possibly due to network issues or incorrect URL configuration.
• Solution: Check the network connection and ensure the text-to-speech service URL is correctly configured and accessible.

Error: Error loading audio file: <error_message>

• Explanation: This error suggests an issue with accessing or reading the saved audio file.
• Solution: Verify the file path and permissions to ensure the file can be accessed and read by the system.
