Build a Presentation Coaching Application with Recall

In this tutorial, a virtual presentation coaching application is built using Recall API and Node.js. The application allows users to add a Recall bot into a Zoom call, remove it, and get insights once the call is over. The key steps include setting up an express application, creating a reusable recall() helper method, adding bots to a Zoom call, making bots leave a Zoom call, showing data from calls, getting all speaker usernames, displaying each speaker's turn count, and calculating each speaker's speaking time. The application can be further enhanced by performing additional analysis using the data returned by Recall and Deepgram.
