🎙️ Convert Voice Notes to X Posts with Google Drive and AssemblyAI

🎙️ 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.
