🎙️ Voice Note to Tweet: Turn Audio Ideas into X Posts with n8n
A lean, 3-node automation that turns voice memos into tweets — so creators can capture ideas on the go and publish fast, without typing.
Capture inspiration the moment it strikes — even when you’re not at your desk. This 3-node workflow lets content creators, coaches, and solopreneurs turn voice memos into X (Twitter) posts automatically.
Just record a voice note, upload it to a Google Drive folder, and n8n will:
🛠️ Step-by-Step Setup Instructions
1. Prepare Google Drive Folder
- Create a folder:
Voice Notes to Tweet
- Enable Google Drive API in your n8n credentials
- Share the folder with your automation account (if needed)
2. Set Up AssemblyAI (or Whisper)
- Sign up at assemblyai.com
- Get your API key
- In n8n, add a credential for HTTP Request or use a dedicated node
🔁 Alternative: Use OpenAI’s Whisper API if preferred
3. Connect X (Twitter) Account
- Use n8n’s X (Twitter) node
- Authenticate with your app key, secret, access token
- Ensure write permissions
4. Deploy the Workflow
- Import the JSON below
- Replace placeholder credentials:
{{GOOGLE_DRIVE_FOLDER_ID}}{{ASSEMBLYAI_API_KEY}}{{TWITTER_CREDENTIAL}}
- Activate the workflow
Now, every time you upload a .m4a, .mp3, or .wav file to your folder — it becomes a tweet.
🔄 Workflow Explanation
- Watch Google Drive → Triggers when a new voice note is added
- Transcribe Audio → Sends file to AssemblyAI for speech-to-text
- Post to X (Twitter) → Publishes the transcript as a tweet
Optional: Add a Slack approval step if you don’t want auto-posting.
