Overview
This node converts a given text prompt into speech audio using the Wiro AI text-to-speech service. It is useful for automating voice generation tasks such as creating audio narrations, voiceovers, or spoken responses in various languages and voice styles. For example, you can input marketing copy or chatbot replies and generate corresponding speech files to enhance user engagement or accessibility.

- Polls the Wiro AI service until the speech generation task completes or fails.
Troubleshooting
- Missing or invalid API credentials: Ensure that the API key and secret are correctly configured in the node credentials.
- API response missing task ID or socket token: This indicates an issue with the request or the API service. Check the prompt and parameters for correctness and verify service availability.
- Task status "failed": The speech generation did not succeed. Review the input parameters and try again.
- Network or timeout errors during polling: Verify network connectivity and API service status.
