What do you understand by natural language processing? Explain with the help of an example.

Natural Language Processing (NLP) helps a computer understand, interpret and respond to human language (both spoken and written). It converts human language into a form that the computer can process, so that meaningful actions or responses can be produced.

Example: In voice search on Google/YouTube, when we speak a query like "Show ICSE Class 9 physics videos", the system understands the spoken words and performs the required search.
