voice.js

// The function below was developed late last year by @stybbe, published in
  //  Screeps Slack's #share-thy-code channel. No license was applied; all  
  //  rights remain with the author. Minor fixes were made by @SemperRabbit 
  //  to get it working again.

  // NOTE: that this code works in chrome and firefox (albiet quietly
  //  in firefox) but not the steam client.
