How It Works
This workflow is designed for efficient, end-to-end processing of audio files. Here's a step-by-step breakdown of its operation:
- Trigger (Manual or Automatic): The workflow can be initiated manually, or automatically whenever a new .m4a audio file is uploaded to your specified Google Drive folder. (Refer to the 'On File Created Trigger' node, currently disabled, for automatic setup).
- Optional Human Approval: An email is sent to a designated user for approval. The workflow pauses, awaiting confirmation before proceeding with transcription and report generation, enabling a critical human-in-the-loop step.
- Audio File Retrieval: The workflow searches your specified Google Drive folder for the latest .m4a audio file and downloads it for processing.
- OpenAI Transcription: The downloaded audio file is sent to OpenAI for highly accurate transcription, converting spoken words into raw text.
- Structured JSON Summarization: The raw transcript is then fed into OpenAI (GPT-4o-mini) to generate a detailed, structured JSON report, ideal for programmatic analysis and database integration. This includes key points, action items, sentiment, and more.
- Markdown Report Generation: Concurrently, a second OpenAI process transforms the summary into a professional, human-readable Markdown document, perfect for sharing and quick review.
- Save Reports to Google Drive: The raw transcript, structured JSON report, and Markdown report are all automatically saved back into your designated Google Drive folder.
- User Notification: Finally, direct links to all generated reports are sent to designated users via Gmail and Telegram, ensuring immediate access to the processed information.
