support_speech_attribute.js

function support_speech_attribute() { 
  var elem = document.createElement('input'); 
  return 'speech' in elem || 'onwebkitspeechchange' in elem; 
  // update based on https://github.com/Modernizr/Modernizr/wiki
  //  - 'webkitSpeech' in elem -> does`t work correctly in all versions of Chromium based  
  //  browsers: can return false even if they have support for speech (http://i.imgur.com/2Y40n.png)
  //  - testing with 'onwebkitspeechchange' seems to fix this problem
}




    

Tested only on Chrome and Firefox.
