Automated Podcast Production: Document to Dynamic Audio
detail.loadingPreview
This workflow fully automates podcast creation, transforming a simple document into a dynamic audio episode. It uses AI to generate scripts, produce multi-speaker audio with preferred voices, and then compiles and uploads the final podcast to Google Drive. Streamline your content production and effortlessly expand your reach.
About This Workflow
This powerful n8n workflow revolutionizes podcast production by automating the entire process from a text document to a polished audio episode. Starting with a Google Drive trigger, it ingests your document, uses advanced AI (OpenAI and Langchain) to craft a compelling podcast script, and intelligently determines participant roles. Each speaker's lines are then transformed into natural-sounding audio using distinct voices. These individual audio segments are stored, combined, and then processed into a complete podcast. Finally, the finished audio file is automatically uploaded back to Google Drive, offering an end-to-end, hands-free solution for consistent and high-quality audio content generation.
Key Features
- Document-to-Podcast Automation: Automatically converts written documents into full-fledged podcast episodes with minimal manual intervention.
- AI-Powered Script Generation: Utilizes OpenAI and Langchain to intelligently craft dynamic and engaging podcast scripts from your raw text input.
- Multi-Speaker Audio Synthesis: Generates natural-sounding audio for multiple participants, allowing for distinct and preferred AI voices to create dynamic conversations.
- Seamless Content Storage & Integration: Stores individual audio segments in a database (e.g., MongoDB) and intelligently combines them into a cohesive final podcast production.
- Automated Google Drive Integration: Triggers the workflow upon new document uploads and automatically publishes the completed podcast directly to your specified Google Drive folder.
How To Use
- Google Drive Trigger: Configure this node to monitor a specific folder in your Google Drive. Any new text documents (e.g.,
.txt,.docx,.pdfthat can be converted to text) added here will initiate the workflow. Ensure your Google Drive credentials are connected. - OpenAI Chat Model & Generate Podcast Script from Text: Connect your OpenAI API key credentials. Within the 'Generate Podcast Script from Text' node, define a clear prompt. This prompt will instruct the AI on how to transform your document's text into a structured podcast script, including elements like intro, outro, and speaker assignments.
- Determine Participants: Adjust this 'Set' node to define how participant roles are identified or assigned from the AI-generated script. This could involve parsing specific tags (e.g.,
[SPEAKER_A],[SPEAKER_B]) or using logic to distribute dialogue among a predefined number of speakers. - Generate Speaker Audios with Prefered Voices: Provide your OpenAI API key for text-to-speech. In this node, map the script's speaker segments to specific voice IDs or settings available through the OpenAI TTS API to create distinct and natural-sounding voices for each participant.
- Store Files in MongoDB (or similar storage): Configure this 'HTTP Request' node with your MongoDB API endpoint and authentication details to store the generated individual audio segments. Ensure your database is set up to receive the audio data (e.g., Base64 encoded) and return unique IDs.
- Generate Podcast: This 'HTTP Request' node is crucial for combining the audio. It will call your custom audio stitching service (or a third-party API). Ensure the payload sends the URLs or IDs of the individual audio segments in the correct order for assembly, along with any desired background music or sound effects.
- Upload File to Google Drive: Set up this node to upload the final assembled podcast audio file back to a designated folder in your Google Drive, making it ready for distribution.
