How The Workflow Operates

1. Initiate with a Form: The process begins when you submit a script, a desired voice, and language through a simple n8n Form Trigger.
2. Synthesize Speech: The workflow sends the text to Google's Text-to-Speech API, which generates the audio and returns it as a base64 encoded file.
3. Process and Upload: The data is converted into a binary audio file and uploaded directly to a specified folder in your Google Drive.
4. Enrich Metadata: The workflow then retrieves the audio file's duration using the fal.ai ffmpeg API, adding valuable metadata.
5. Log Everything: Finally, it creates a new record in your Airtable base, storing the asset name, description (your script), content type, file URLs from Google Drive, and the audio duration for perfect organization.

What You'll Need

To use this workflow, you will need active accounts for the following services:

• Google Cloud oAuth2 Client Credentials: With the Text-to-Speech API enabled.
• Google Drive: For audio file storage.
• Airtable: For logging and asset management.
• fal.ai: For the ffmpeg API used to get audio duration.
