Welcome to the future of reading!


Have you ever imagined a more dynamic way to engage with the extensive text we encounter daily? Imagine transforming static PDFs into something more interactive and engaging. That's precisely the focus of my recent experiment, and I'm excited to share the insights with you. Whether you're an avid reader, a busy professional, or intrigued by AI innovations, I believe you'll find this intriguing.


Here’s how we're transforming our favorite books, reports, or articles into new auditory companions:


  • Text Extraction: We begin by employing Python libraries to intelligently extract text from PDFs, a critical step to ensure the quality of the audio matches the text.

  • Chunking it Right: The text is then segmented into smaller portions to meet OpenAI's Text-to-Speech context window.

  • Voicing the Words: AI then adds a natural, easy-to-understand voice to the text, creating an experience akin to a friend reading aloud to you.

  • Stitching the Sound: These segments are seamlessly combined into a complete audio file, akin to crafting an auditory tapestry.

  • Adding a Dash of Visuals: The project goes further by synchronizing the audio with a cover image, producing a simple yet elegant video file for platforms like YouTube.


Below is the outcome of my experiment today, where I transformed a PDF containing a 1784 essay by the philosopher Immanuel Kant titled - “What Is Enlightenment?” - into the accompanying video.




This project transcends mere technological novelty; it's about enhancing accessibility and convenience. Imagine students learning on the move, professionals staying abreast of industry developments, or book enthusiasts enjoying literature without turning a page.


The adventure doesn't end with audiobooks. At Prex Studio, we continuously explore the vast possibilities of AI. We've uploaded the code for this project to our GitHub repository at GPT-Examples.


As we at Prex Studio continue to innovate and explore new horizons, we invite you to join us. Whether you're a technology enthusiast, a lifelong learner, or someone looking to simplify life, AI offers something for everyone. Let's embark on this journey together, transforming our interaction with information, one audiobook at a time.
