// speech input for inputs
// by @alrra


// `webkitSpeech` in elem 
// doesn`t work correctly in all versions of Chromium based browsers.
//   It can return false even if they have support for speech i.imgur.com/2Y40n.png
//  Testing with 'onwebkitspeechchange' seems to fix this problem

// this detect only checks the webkit version because
// the speech attribute is likely to be deprecated in favor of a JavaScript API.

// FIXME: add support for detecting the new spec'd behavior
