Generate & Upload an Audio Summary of a WordPress (or Woocommerce) Article

This workflow automates the process of summarizing or transcribing a WordPress article, converting the text into speech using Eleven Labs API, and uploading the resulting MP3 file back to WordPress.

How It Works

1. Trigger – The workflow starts manually when the user clicks “Test Workflow”.
2. Retrieve Article – It fetches a WordPress article based on a given post ID.
3. Summarize or Transcribe – An LLM (GPT-4o-mini) generates either:
   • A summary of the article, or
   • A full transcription, depending on the chosen prompt.
4. Generate Speech – The processed text (summary or transcription) is converted into an MP3 audio file using Eleven Labs API.
5. Upload MP3 to WordPress – The generated MP3 file is uploaded to WordPress.
6. Update WordPress Post – The article is updated with an embedded audio player, allowing users to listen to the summary or transcription.

Set Up Steps
1. WordPress API Credentials
• Configure your WordPress API credentials in n8n.
2. Eleven Labs API Key
• Obtain an API Key from Eleven Labs and configure it in n8n.
3. Choose Between Summary or Transcription
• Modify the AI prompt to either generate a summary or keep the full transcription.
4. Test the Workflow
• Run the workflow and ensure the MP3 file is correctly generated and uploaded.

💡 Customization Options
• Modify the AI prompt to switch between a summary and a transcription.
• Change the voice model in Eleven Labs for different speech styles.
• Adjust output format to higher/lower quality MP3.

🚀 This automation improves content accessibility and engagement by allowing users to listen to a summarized or full version of the article.
