A static site demonstrating real-time audio transcription via Amazon Transcribe over a WebSocket.

This demo app uses browser microphone input and client-side JavaScript to demonstrate the real-time streaming audio transcription capability of Amazon Transcribe using WebSockets.

Check out the Amazon Transcribe WebSocket docs.

Even though this is a static site consisting only of HTML, CSS, and client-side JavaScript, there is a build step required. Some of the modules used were originally made for server-side code and do not work natively in the browser.

We use browserify to enable browser support for the JavaScript modules we require().

1. Clone the repo
2. run npm install
3. run npm run-script build to generate dist/main.js.

Once you've bundled the JavaScript, all you need is a webserver. For example, from your project directory:

npm install --global local-web-server
ws

This project is based on code written by Karan Grover from the Amazon Transcribe team, who did the hard work (audio encoding, event stream marshalling).
