Session awareness

Every time the user engages VUIs, there is specific data the application needs to remember. A good example of this would be the name of the user so that the application addresses the user by their first name. Another good example is the cooking voice application that you will build in Chapter 6, Building a Cooking Application Using Alexa. When a user is making use of cooking app, there are times when the application asks the user to saute the chopped onions till brown. Five minutes later, the user might come back and ask for the next step. The cooking application needs to be smart enough to understand that each step can take minutes to carry out and that the user's session must be maintained in order to correctly interact with the user.
