This n8n workflow automates the process of converting text received via a webhook into spoken audio using OpenAI’s text-to-speech capabilities. It works by triggering upon a POST request to a designated webhook URL, which sends the input text to the OpenAI API configured for voice synthesis. The resulting audio is then returned directly as a response to the initial webhook call.
The workflow includes the following key steps:
1. The webhook node listens for incoming POST requests on a specified endpoint.
2. Once triggered, the text contained in the request body (under ‘text_to_convert’) is sent to OpenAI’s API through the OpenAI node.
3. The OpenAI node is configured to generate audio in the ‘fable’ voice style.
4. After processing, the generated audio is returned directly as a response to the webhook, allowing seamless integration for applications needing on-demand text-to-speech conversion.
This setup is particularly useful for automating voice responses, creating audio content dynamically, or integrating with voice-enabled apps and services where converting text data to speech in real-time enhances user interaction.
