🎙️ 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.
