    •   The Edge team has investigated and it appears the site is doing browser detection and incorrectly recognizing Edge as Chrome and throws an exception when trying to use unsupported API webkitSpeechRecognition. 


      Also, it is recommended that the site should have an Edge browser check at the end of the function after doing a check for Chrome. 

      Right now the site first detects browser as Edge but then in the Chrome detection logic, they detect browser as Chrome since the Edge UA contains Chrome. So final value for browser=chrome.



      //Fuction for browser detection

          function browser_detector() {

              var isOpera = (!!window.opr && !!opr.addons) || !!window.opera || navigator.userAgent.indexOf(' OPR/’) >= 0;

              if (isOpera) {

                  var browser = "opera";


              // Firefox 1.0+

              var isFirefox = typeof InstallTrigger !== 'undefined’;

              if (isFirefox) {

                  var browser = "firefox";


              // At least Safari 3+: "[object HTMLElementConstructor]"

              var isSafari =‘Constructor’) > 0;

              if (isSafari) {

                  var browser = "safari";


              // Internet Explorer 6-11

              var isIE = /@cc_on!@/ false || !!document.documentMode;

              if (isIE) {

                  var browser = "IE";


              // Edge 20+

              var isEdge = !isIE && !!window.StyleMedia;

              if (isEdge) {

                  var browser = "edge";


              // Chrome 1+

              var isChrome = !! && !! || navigator.userAgent.indexOf(' OPR/’) >= 0 || navigator.userAgent.indexOf(‘Chrome’) >= 0;

              if (isChrome) {

                  var browser = "chrome";


              // Blink engine detection

              var isBlink = (isChrome || isOpera) && !!window.CSS;

              if (isBlink) {

                  var engine = "blink";



              return browser;
