You can now define a response for your Amazon Lex chatbot directly from the AWS Management Console. A response consists of messages dynamically selected from a group of pre-defined messages, populated by the developer. Messages in these message groups can be simple text, or you can use custom markup. In addition, you can also display a response card as part of the response. The responses capability simplifies building dynamic conversations with Amazon Lex.  In addition, you can use Speech Synthesis Markup Language (SSML) in a text response.
