Overview
The node interacts with the ElevenLabs API, specifically providing functionality related to voice management under the "Voice" resource. The "List Voices" operation retrieves a list of available voices from the service. This can be useful for applications that need to present users with voice options for text-to-speech or other audio generation tasks.
Common scenarios include:
- Fetching all available voices to allow users to select one for speech synthesis.
- Filtering voices by type (e.g., premade vs. custom) to tailor user choices.
- Integrating voice selection dynamically in workflows that generate audio content.
Practical example:
- A content creation workflow where the user wants to convert text into speech using a specific voice. The node lists voices so the user can pick one before generating audio.
Properties
| Name | Meaning |
|---|---|
| Simplify Output | Whether to return a simplified version of the response. |
| Include Premade | Whether to include premade voices in the response. |
Additionally, there is a notice property informing users that the node is in beta and under active development, with links for more information and support.
Output
The output JSON contains the list of voices retrieved from the ElevenLabs API. If "Simplify Output" is enabled, the response is transformed into a simpler structure focusing on key voice attributes for easier consumption in workflows.
If binary data were involved (not indicated here), it would typically represent audio files or similar, but this operation only returns metadata about voices.
Dependencies
- Requires an API key credential for ElevenLabs API authentication.
- The node makes HTTP POST requests to
https://api.elevenlabs.io/v1. - No additional external dependencies are indicated.
Troubleshooting
Common issues:
- Invalid or missing API key will cause authentication errors.
- Network connectivity problems may prevent reaching the ElevenLabs API.
- Using the node while it is in beta might lead to unexpected behavior or incomplete features.
Error messages:
- Authentication failures usually indicate invalid credentials; verify the API key.
- API rate limits or quota exceeded errors require checking usage limits on the ElevenLabs account.
- Unexpected response formats could mean changes in the API; check for node updates.
