How Can a Computer Understand You?

Imagine you're telling a friend about your day, they understand you because they know the words and how sentences work. A computer tries to do the same thing, but it uses rules and examples instead of knowledge from experience.

When a computer hears your voice, it turns the sounds into numbers, like a special code. Then it compares those numbers with what it knows about words and meanings. If the match is good enough, the computer thinks it understands you.
