Put FACES to your NotebookLM AI Podcast audio! 2 methods!

Introduction

In a world driven by the advancements of AI technology, creative solutions are continually emerging, allowing us to elevate our content and enhance user engagement. Today, we'll explore how to add visual elements to your NotebookLM AI-generated podcast audio using two innovative methods. If you missed the introduction, don’t worry! We’ll walk through the essential steps on how to combine audio and visuals effectively to enrich the podcasting experience.

Getting Started with NotebookLM

Recently, I shared my experience with NotebookLM, a Google service that enables users to upload their knowledge base in text form—such as books and courses—and creates a fully interactive chatbot that engages users in conversation about the content. This service has an incredible feature for generating AI podcasts that simulate engaging dialogues between two voices discussing the material you’ve uploaded.

Creating the Podcast

To demonstrate the power of NotebookLM, I created a knowledge base called Bob Doyle Media using the Otter transcription service. This allowed me to consolidate information about my channel's focus areas and generated a podcast audio file featuring exciting discussions.

Enhancing Your Audio with Visuals

Once you have your podcast audio file, the goal is to give it a face—literally! Here are two methods to achieve this:

Method 1: Facial Animation with Hedra

Download Your Audio: Begin by downloading the audio file generated by NotebookLM.
Audio Editing: Use an audio editor like Audacity to split the audio into separate tracks—for instance, a male voice and a female voice. Export these tracks as separate audio files.
Animation with Hedra: Upload these audio files into Hedra, a facial animation platform. For each audio file, create a stylized character face and upload the voice to animate it in accordance with the dialogue.
Combine and Edit: Using video editing software, place the animated clips side-by-side to generate the video podcast.

Method 2: Enhancing Realism with Live Portrait Technology

Create a Driving Video: Record a video of a person or character delivering the audio without spoken words or excessive movements.
Combine with Facial Animation: Transfer the facial movement generated in Hedra to a more realistic video source by utilizing live portrait technology.
Using Comfy UI for Facial Animation: Once you have both the driving video and the base facial video, upload them into Comfy UI to apply the animated movements to the realistic presentation.
Finishing Touches: Export the final video and examine the combined effects of animated features and audio—for a more dynamic presentation.

Adding Voice Diversity

Finally, to enhance the audio quality and differentiate voices, employ voice conversion tools like Eleven Labs or RVC to give a unique twist to each character's audio track.

Conclusion

By following these steps, you can easily create visually appealing video podcasts that stand out and captivate your audience. The integration of audio and dynamic visuals creates an engaging multimedia experience that can significantly improve how your content is received.
