detail.loadingPreview
Transform your PDF documents into engaging audio podcasts effortlessly. This n8n workflow leverages AI to extract content, generate a professional script, and convert it into high-quality spoken audio, ready for sharing.
About This Workflow
This powerful n8n workflow revolutionizes content creation by automating the entire process of turning a PDF document into a ready-to-publish podcast audio file. Starting with a simple PDF upload, the workflow intelligently extracts the core text. It then hands off this content to an advanced AI model (Google Gemini) that crafts a structured, engaging, and time-specific podcast script. Finally, the script is converted into natural-sounding speech using Gemini's Text-to-Speech capabilities, complete with proper WAV formatting, and saved directly to your chosen location. Say goodbye to manual scriptwriting and recording – create compelling audio content at scale.
Key Features
- Seamless PDF Content Extraction: Automatically pulls text from your uploaded PDF documents, preparing them for AI processing.
- AI-Powered Podcast Script Generation: Utilizes Google Gemini to generate engaging, structured podcast scripts (5-7 minutes) from your extracted text, adhering to conversational language and specific storytelling requirements.
- High-Quality Text-to-Speech (TTS): Converts the AI-generated script into natural-sounding audio using Gemini's advanced TTS engine, with customizable voice options.
- Automated WAV File Creation: Correctly processes and formats the raw audio output from the TTS service into a standard WAV file, ready for immediate use.
