Text to Speech (OpenAI)

For OpenAI, this workflow converts text into speech using a simple manual trigger. Users can easily set the input text and select a voice, then send a request to OpenAI's TTS API to generate an audio file. Ideal for creating audio content from written text, it streamlines the process and enhances accessibility.

    • Problem Solved

    This workflow automates the process of converting text into speech using OpenAI's Text-to-Speech (TTS) API, addressing the need for efficient audio content creation without manual intervention.

    Workflow Steps

  • Trigger the Workflow: The process starts when the user clicks on the 'Test workflow' button.
    2. Set Input Text and Voice: The user-defined text ('The quick brown fox jumped over the lazy dog.') and the selected voice ('alloy') are set for the TTS conversion.
    3. Send HTTP Request: An HTTP POST request is sent to OpenAI's TTS endpoint, including the model, input text, and voice parameters.
    4. Receive Audio File: The response from OpenAI contains a binary audio file in .mp3 format, which is the spoken version of the input text.

    • Customization Guide

  • To change the input text, modify the input_text value in the 'Set input text and TTS voice' node.
    - To select a different voice, replace the voice value in the same node. Refer to the OpenAI TTS Docs for available voice options.
    - You can replace the manual trigger with another type of trigger based on your specific use case, such as a webhook or scheduled trigger.
