Generate Audio from Text via OpenAI TTS Webhook

This n8n workflow automates text-to-speech (TTS) conversion using OpenAI's advanced voice synthesis. It starts with a Webhook node that receives a POST request containing text input. The text is then processed by the OpenAI node, which leverages the TTS API to generate high-quality audio in various voices and formats.

Finally, the Respond to Webhook node returns the binary audio file directly in the HTTP response, enabling seamless integration into web apps, chatbots, or IoT devices. Benefits include reduced manual audio production, consistent voice output, and scalable automation without custom coding.

Ideal use cases: Content creators generating podcasts from scripts, customer support bots providing voice responses, educational apps converting lessons to audio, or industrial IoT systems announcing alerts via voice. Setup requires only an OpenAI API key and activating the workflow for production webhook use.
