This is the third story in our continuing series covering the basics of AI. While it isn’t necessary to read the first article, which covers neural networks, doing so may add to your understanding of the topics covered in this one. If you’d like to know how computers “see,” visit the second article to learn about computer vision and image processing. 

When computers process text or audio from humans, they’re just looking at data. You can whisper “I love you” or drop an F-bomb, the machines just see 1’s and 0’s. In order for AI to understand what you’re saying, turn those words into an action, and then output something you can understand, they rely on something called natural language processing (NLP), which is exactly what it sounds like.
