Why we included this project

If you have an Amazon Lex bot working but no polished front end for it, this project gives you a head start. It provides a responsive chat interface that works either as a full-page app or as a widget you can embed in an existing site, and it handles text and voice input in the same component. The voice side does silence detection, transcribes what people say, and lets users interrupt or replay recordings, which helps in hands-free or accessibility-focused setups. It also renders Lex response cards and exposes a JavaScript API, so you can configure the chat and drive it from your own code. Since this is an AWS sample, plan to connect it to Lex and Cognito rather than a generic chatbot backend, and treat it as a reference implementation to adapt, not a turnkey product.
