####OpenTok Extensions

This repository is a playground for two extensions for the OpenTok JS client API:

1. TB_transcript.js - a small extension which leverages the speech recognition API and the TB signal API to keep synchronized video chat transcripts.
2. TB_highlight_speaker.js - another small extension which highlights the window of the current speaker in a TB session.

####Sample application The sample application requires node.js and npm and is configured to run on port 8000. Steps to get going:

1. edit server.js and enter your TB API key and secret
2. run npm to download node dependencies npm install
3. run node to start the server node server.js
4. navigate to localhost port 8000 and accept the video cam / microphone sharing requests
