Natural Language Processing (NLP) is an important domain of Artificial Intelligence (AI) that
helps computers understand and work with human language. It allows people to talk to
machines in a natural way—just like we talk to each other.

Apps like Siri, Alexa, and Cortana use NLP to listen to our voice and understand what we
are saying. NLP helps computers read, understand, and respond to both spoken and written
language in a meaningful way.
NLP aims to read, decode, understand, and bring logical results to human languages that
make some sense.
