In this series, the author demonstrates how to build a live streaming web application with text captions using Amazon IVS and Deepgram. The main technologies used are Open Broadcast Software (OBS), Amazon Interactive Video Service (IVS), and Deepgram's speech-to-text API. Two versions of the project are built: one using vanilla HTML/Javascript, focusing on creating a front-end with limited back-end; and another using Vue.js/Node.js for added functionality and security features. The author provides step-by-step instructions for setting up OBS, Amazon IVS, and Deepgram, as well as code examples for integrating these technologies into the web application.
