Amazon Echo and Alexa have shown that voice interfaces provide significant benefits to users – interactions are easy, fast, and context-driven. In this hands-on session, you’ll see how to add compelling voice and chat interfaces to your mobile apps, using Amazon Lex for processing conversations and triggering corresponding actions in your backend systems, all without having to manage any infrastructure. You’ll leave knowing how to build apps that can “Find me a nearby hotel” or “Reorder supplies for the copier”.
