Workflow Name

Text to Speech (OpenAI)

Key Features and Highlights

This workflow leverages OpenAI’s Text-to-Speech (TTS) API to convert input text into natural and fluent speech audio files in MP3 format. Users can customize the input text and select from multiple voice styles (default is "alloy") to easily generate high-quality voice content.

Core Problem Addressed

Enables fast and automated conversion of text content into speech, effectively reducing the high cost and low efficiency associated with manual recording. It is suitable for various voice output scenarios such as audiobooks, voice assistants, and online education.

Application Scenarios

  • Content creators producing audio versions of articles or podcasts
  • Voice interaction modules in customer service systems
  • Generation of voice prompts in smart devices or applications
  • Creation of speech-assisted materials for education and training

Main Workflow Steps

  1. Manual Trigger — Initiate the workflow via a manual button for easy testing and debugging.
  2. Set Input Text and Voice Parameters — Predefine or dynamically pass the text to be converted and select the desired voice type within the node.
  3. Call OpenAI Text-to-Speech API — Send an HTTP request to OpenAI’s TTS endpoint with the text and voice parameters.
  4. Receive and Output Audio File — Obtain the MP3 audio file returned by the API for subsequent playback or storage.

Involved Systems or Services

  • OpenAI Text-to-Speech API
  • n8n Automation Platform (nodes include Manual Trigger, Set, HTTP Request)

Target Users and Value

This workflow is ideal for enterprise developers, content creators, product managers, and anyone needing automated voice content generation.
