Result of the layers
Amazon Lex used to convert the relevant Naturan Language Understanable string from Automatic Speech Synthesis Recognition and to build the service and mobile application that support engaging lifelike interaction. Then the amazon skill information to generate the interaction models of intents. From the sample of utterances to match that interaction model schema to get the response of the given input speech. Amazon Polly will add speech response to the logic behind program using Amazon Lex.
