Quick Overview This workflow receives a webhook request with an audio sample URL, voice name, and script, clones a voice and generates a matching voiceover using Smallest AI, uploads the MP3 to Google Drive, logs the voice ID in Google Sheets, and returns a public link in the webhook response. How it works Receives a POST webhook request containing an audio_url, voice_name, and script text. Downloads the provided voice sample file from the audio_url. Sends the sample to Smallest AI Voice Cloning to create a new voice profile and extracts the returned voiceId. Truncates the script text to a safe length and synthesizes speech with Smallest AI using the cloned voice ID. Uploads the generated MP3 voiceover to Google Drive and updates its sharing settings to be publicly readable. Appends the cloned voice ID and voice name to a Google Sheets “voice library” spreadsheet and returns a JSON response with the voice ID, Drive link, and timestamp. Setup Create a Smallest AI API key, store it securely in n8n, and replace the hardcoded Authorization: Bearer ... header used for voice cloning.

This workflow allows you to recognize a folder with receipts or invoices (make sure your files are in .pdf, .png, or .jpg format). The workflow can be triggered via the "Test workflow" button, and it also monitors the folder for new files, automatically recognizing them. Video Demo https://youtu.be/mGPt7fqGQD8 1. n8n import glitch After import, the trigger node "When clicking 'Test workflow'" might be disconnected. You need to connect it via 2 arrows to "Google Sheets1" and "Google Drive" nodes. So, the workflow has 2 triggers - via button, and via Google Sheets "new file" event - both of these triggers should be connected to 2 nodes. Here is how it should look like: https://ocr.oakpdf.com/n8n_fix.png 2.
