ElevenLabs Text to Speech:
The ElevenLabsTextToSpeech node is designed to convert written text into spoken words, providing a seamless way to generate audio content from textual input. This node leverages advanced text-to-speech technology to produce natural-sounding speech, making it an invaluable tool for creating voiceovers, audiobooks, and other audio-based applications. By allowing you to select different voices and adjust parameters such as stability and text normalization, this node offers flexibility and control over the speech synthesis process. Its primary goal is to transform text into high-quality audio output, enhancing the accessibility and engagement of your content.
ElevenLabs Text to Speech Input Parameters:
voice
This parameter specifies the voice to be used for speech synthesis. You can connect it from a Voice Selector or use an Instant Voice Clone. The choice of voice can significantly impact the tone and style of the generated speech, allowing you to tailor the audio output to suit your specific needs.
text
The text parameter is the core input for this node, representing the written content you wish to convert into speech. It supports multiline input, enabling you to provide extensive text passages. The clarity and coherence of the output speech are directly influenced by the quality and structure of the input text.
stability
This parameter controls the voice stability, with a default value of 0.5. It ranges from 0.0 to 1.0, where lower values offer a broader emotional range, and higher values result in more consistent but potentially monotonous speech. Adjusting this setting allows you to fine-tune the expressiveness of the synthesized voice.
apply_text_normalization
This option determines the mode of text normalization applied during speech synthesis. It offers three settings: "auto," "on," and "off." "Auto" lets the system decide the best approach, "on" always applies normalization, and "off" skips it. Text normalization can enhance the naturalness and intelligibility of the speech output.
model
The model parameter is a dictionary that includes settings such as model ID, similarity boost, speed, and optional features like speaker boost and style. These settings influence the characteristics and performance of the speech synthesis, allowing for customization based on your requirements.
language_code
This parameter specifies the language code for the text-to-speech conversion. If left blank, the system may default to a standard language setting. Providing a specific language code ensures that the speech synthesis aligns with the linguistic nuances of the input text.
seed
The seed parameter is used to initialize the random number generator for the speech synthesis process. It can help achieve consistent results across multiple runs by controlling the randomness in the voice generation.
output_format
This parameter defines the format of the audio output, such as MP3 or WAV. Choosing the appropriate format is crucial for compatibility with different playback systems and applications.
ElevenLabs Text to Speech Output Parameters:
audio
The primary output of this node is the audio parameter, which contains the synthesized speech in the specified format. This audio output can be used in various applications, from multimedia projects to accessibility tools, providing a versatile solution for converting text into engaging spoken content.
ElevenLabs Text to Speech Usage Tips:
- Experiment with different voices to find the one that best matches the tone and style of your project.
- Adjust the stability parameter to balance between emotional expressiveness and consistency in the speech output.
- Use the apply_text_normalization setting to enhance the clarity and naturalness of the synthesized speech, especially for complex or technical text.
ElevenLabs Text to Speech Common Errors and Solutions:
Invalid voice selection
- Explanation: The selected voice may not be available or properly configured.
- Solution: Ensure that the voice is correctly connected from a Voice Selector or Instant Voice Clone and is supported by the system.
Text input too short
- Explanation: The provided text does not meet the minimum length requirement.
- Solution: Ensure that the text input is at least one character long and contains meaningful content for conversion.
Unsupported language code
- Explanation: The specified language code is not recognized or supported by the system.
- Solution: Verify that the language code is correct and supported by the ElevenLabs text-to-speech service.
Output format not recognized
- Explanation: The chosen output format is not supported.
- Solution: Select a valid output format, such as MP3 or WAV, that is compatible with the ElevenLabs text-to-speech service.
