This document summarizes a presentation about building bots with Amazon Lex and Amazon Polly. It introduces Amazon Lex for building conversational bots and Amazon Polly for converting text to lifelike speech. It provides an example of a "Coffee Bot" that takes voice or text orders for coffee drinks and confirms the order using synthesized speech. The presentation encourages attendees to build their own Coffee Bot by setting up intents and slots in Lex, integrating it with a Lambda function for fulfillment, and using Mobile Hub and CloudWatch for analytics.
