AssemblyAI Real-Time Transcription Browser Example

This open-source repo provided by AssemblyAI displays how to use our real-time API in the browser!

In this app, we grab an audio stream from the user's computer and then send that over a WebSocket to AssemblyAI for real-time transcription. Once AssemblyAI begins transcribing, we display the text in the browser. This is accomplished using Express for our backend and the AudioWorklet to process the raw audio.
