Convert documents to podcast audio with GPT-4o & OpenAI TTS

This workflow contains community nodes that are only compatible with the self-hosted version of n8n.

What it does This n8n workflow delivers a comprehensive, automated solution for transforming written content into dynamic, multi-speaker podcast audio. It automatically detects new documents in Google Drive, leverages advanced AI to craft a detailed podcast script, generates individual audio segments for each speaker, uploads these segments to a dedicated file storage, seamlessly concatenates them into a full episode, and finally, saves the completed audio back into Google Drive. This end-to-end pipeline significantly streamlines your content-to-audio production process.

How it works The workflow is a powerful orchestration of AI and automation, designed to take your raw document and deliver a polished audio product.

1. Document Ingestion & Text Extraction 📄➡️💬 Your journey begins when you simply place a document in a designated Google Drive folder.

2. AI-Powered Script Generation 🧠✍️ With the text extracted, the workflow hands it over to an AI scriptwriter.

3. Dynamic Audio Generation & Storage 🗣️💾 Once the script is ready, each piece of dialogue is brought to life with distinct voices.

4. Generate Podcast 🔗🎧📂 Finally, all the individual audio pieces are assembled into one complete podcast episode.
