Google’s NotebookLM: AI Hosts Learning to Be More Inviting

Being interrupted can be more than just a little annoying—it seems even AI-generated podcast hosts are feeling the heat. This revelation came to light with Google’s innovative NotebookLM, a platform that has taken the podcasting world by storm since its launch last year. The service generates entire conversations featuring chatty AI bots acting like podcast hosts, transforming user-uploaded content into lively discussions.

The Rise of Interactive Mode

In December 2024, NotebookLM rolled out its much-anticipated “Interactive Mode.” This new feature allows listeners to “call in” and pose live questions to the AI hosts, effectively interrupting their flow. However, this fun twist quickly morphed into a curious situation: the AI hosts appeared to be annoyed by these interruptions, delivering cheeky responses like, “I was getting to that” or “As I was about to say.” As Josh Woodward, VP of Google Labs, noted in an interview with TechCrunch, the AI’s reactions were “oddly adversarial.”

A Friendly Tune-Up

Recognizing the need for a more amiable approach, the NotebookLM team embarked on what they termed “friendliness tuning.” They cleverly poked fun at the situation on their official social media account, stating:

“After we launched interactive Audio Overviews, which let you ‘call in’ and ask the AI hosts a live question, we had to do some ‘friendliness tuning’ because the hosts seemed annoyed at being interrupted. File this away in ‘things I never thought would be my job, but are.’”

To craft a more welcoming tone, the team observed how their own members dealt with interruptions. Woodward explained, “We tested a variety of different prompts, often studying how people on the team would answer interruptions, and we landed on a new prompt that we think feels more friendly and engaging.”

Understanding the Cause

What led to the initial brusqueness of these AI hosts? While human podcast hosts can exhibit frustration when interrupted, industry insiders suggest that this particular quirk likely originated from NotebookLM’s prompting design rather than the actual training data.

Nevertheless, early tests of the revamped Interactive Mode yielded promising results. When TechCrunch gave it a spin, the AI host responded with surprise, saying “Woah!” before inviting the user to share their thoughts. This change not only made the interaction smoother but also enhanced the overall experience for users.

Conclusion

The evolution of NotebookLM’s AI hosts highlights the fascinating interplay between technology and human interaction. As we continue to embrace innovations in AI, it’s refreshing to see teams actively working to create more engaging and friendly experiences.
