Okay kiddo, so you know how you can hear someone talking and also see their mouth moving at the same time? Well, scientists are trying to teach computers to do the same thing. They are working on making computers understand what people are saying by combining what they hear and what they see.
To do this, they use special computer programs that can analyze sounds and video at the same time. The computer can listen to what a person is saying and also look at their mouth moving to figure out what words they are saying.
This is really important because it can help people who have trouble hearing or communicating. By teaching computers to understand both sound and sight, they can help people who might not be able to hear well or might not be able to speak clearly.
It's kind of like how you might use pictures to help explain a story to someone who doesn't speak the same language as you. Seeing what's happening can help them understand what you're saying even if they can't understand your words.
