· The virtual assistant receives an audio request from the user, it further processes the request in the form of phonemes which are called building blocks of language.

· These phonemes are modified into various requests with the help of Speech-To-text. It’s kept within the JSON file which includes the additional data about the user and the session.

· In the cloud, the JSON will be processed for driving the content and request’s intent.

· Later based on the information available on the internet, the response will be submitted. Intended to be done within a larger JSON file, may it be as SSML or can be as a string.
