The debut of Gemini 3.1 Flash Live could make it harder to know if you’re talking to a robot

Text generated by artificial intelligence often has a particular vibe that gives it away as machine-generated, but it has become harder to pick out those idiosyncrasies as the tech has improved. We may be seeing a similar evolution of generative AI audio. Google has announced a new AI audio model called Gemini 3.1 Flash Live—as the name implies, it’s designed for real-time conversation. It’s rolling out in some Google products starting today, and developers will be able to start building their own chatty robots with the model, too.

Google says this AI is much faster and produces speech with a more natural cadence, aiming to solve a long-running issue with AI-generated speech. Like a chatbot, there’s always a delay between input and output in generative audio systems. Longer delays and unnatural inflection make conversations feel sluggish and harder to follow. Researchers generally believe 300 milliseconds ...
