Generate audio from text using OpenAI's TTS API.

About This Workflow

This workflow leverages OpenAI's powerful Text-to-Speech (TTS) API to convert written text into natural-sounding speech. It's designed to be easily adaptable for various applications requiring audio generation, such as voiceovers, accessibility features, or interactive voice response systems.

Key Features

Integrates with OpenAI's TTS API.
Allows configuration of input text and voice.
Outputs audio in MP3 format.
Includes helpful sticky notes for guidance.

How To Use

Trigger: The workflow starts with a When clicking "Test workflow" manual trigger. You can replace this with any other trigger relevant to your needs (e.g., a webhook, a file upload trigger).
Set Input and Voice: The Set input text and TTS voice node is where you define the text to be converted to speech and the desired voice. The jsonOutput parameter currently holds a sample text and the 'alloy' voice. You can dynamically set these values based on previous nodes or external data.
OpenAI TTS Request: The Send HTTP Request to OpenAI's TTS Endpoint node makes the actual API call to OpenAI. It uses the openAiApi credential to authenticate. Ensure your OpenAI API key is correctly configured in your n8n credentials.
- model: Set to tts-1.
- input: Dynamically pulled from the input_text defined in the previous step.
- voice: Dynamically pulled from the voice defined in the previous step.
Output: The API returns an MP3 audio file. This output can then be further processed, saved, or streamed as needed.
