Overview

The node integrates with the CambAI API to convert text into synthesized speech audio. It allows users to input textual content and specify detailed voice characteristics, producing a custom voice output that matches the description. This is useful for applications such as creating voiceovers, virtual assistants, audiobooks, or any scenario requiring natural-sounding speech synthesis.

For example, you can provide a welcoming message and describe the voice as "A warm and friendly middle-aged woman with a slight British accent," and the node will generate speech audio matching that description.

Properties

Name Meaning
Text The text content that will be converted into synthesized speech.
Voice Description A detailed description of the desired voice characteristics (minimum 18 words/100+ characters).
Additional Options Optional settings including:
• Polling Interval (Seconds): Time between status checks (1-10 seconds).
• Polling Timeout (Seconds): Maximum time to wait for voice generation completion (60-600 seconds).

Output

The node outputs JSON data containing the result of the text-to-voice conversion. This typically includes metadata about the generated audio and a reference or URL to the synthesized speech file. If binary data is returned, it represents the actual audio content of the synthesized voice.

Dependencies

  • Requires an API key credential for authenticating with the CambAI API.
  • Needs network access to https://client.camb.ai/apis.
  • No additional environment variables are explicitly required beyond the API authentication.

Troubleshooting

  • Common Issues:

    • Insufficient detail in the "Voice Description" may lead to unsatisfactory voice synthesis results. Ensure the description meets the minimum length requirements.
    • Network connectivity problems or invalid API credentials will cause request failures.
    • Long texts or complex voice descriptions might increase processing time; adjust polling interval and timeout accordingly.

  • Error Messages:

    • Authentication errors indicate invalid or missing API credentials; verify and update your API key.
    • Timeout errors suggest the voice generation took longer than the specified polling timeout; consider increasing the timeout value.
    • Validation errors on input fields usually mean required properties are missing or do not meet criteria (e.g., too short voice description).
