Explain the areas of applications of Natural Language Processing:

(a) In chatbots

(b) In voice assistants

(a) In Chatbots: Chatbots are created using natural language processing and machine learning to interact with humans in a way that they sound like humans themselves. Depending on the complexities, they can either just respond to specific keywords or can even have full conversations with users.

(b) In Voice Assistants: Voice assistants such as Siri, Alexa or Google Assistant are used to make calls, place reminders, schedule meetings, set alarms, surf the internet, etc. They use a complex combination of speech recognition, natural language understanding and natural language processing to understand what humans are saying and then act accordingly. Thus, these voice assistants have made our life much easier.
