Summary

To create an application that allows room participants to join, communicate, and share transcripts, and also enables live transcription of their microphones, the following key points can be noted: A video call web app project was cloned, and the Twilio Programmable Video JavaScript SDK was used to create a video room. An enhanced version of the MediaRecorder API was used to record the room participants' microphones in 6-second intervals, along with the Transformers.js package alongside a Whisper model to transcribe the audio recordings. The DataTrack API was utilized to share the transcripts among the room participants. A server application was created using Express.js that served static assets and handled video call room creation and access token generation. Live transcription functionality was added by utilizing the MediaRecorder API, sending recorded audio files to the server for transcription, and then displaying the transcript below the webcam feed.
