Adding Dominant Speaker Detection for Twilio Programmable Video with TypeScript
Blog post from Twilio
The project aims to build a video chatting application with dominant speaker detection using Twilio Programmable Video and TypeScript. The application allows participants to join rooms, mute audio/video, and detect the dominant speaker in real-time. To achieve this, the developers used the Twilio Client Library, TypeScript, and Parcel for bundling and hot-module replacement. The application is built on top of an existing base project using the Twilio Node Helper Library for back-end authentication and the Twilio Programmable Video JavaScript SDK for front-end video. The dominant speaker detection feature uses CSS classes to highlight the active participant's video stream and an event handler to wire up with the `dominantSpeakerChanged` event emitted by the Twilio Programmable Video JavaScript SDK.
