I have made a game that uses speech recognition and speech synthesis. Its working on the PC in any browser and all the controls are shown as in the image in the link below: (you have to manually paste it in browser because i am not allowed to post urls)
Using Intel XDK i converted my game into and android .apk file but it does'not work on android.
I used the if, else conditions to make sure that if the speech recognition or synthesis is not supported then the browser should return an error message "This browser does not support Speech recognition and synthesis". And the browser generated it. It means the android browser is not supporting speech functionality in android
*Point: Its not the issue of Construct 2 or Intel Crosswalk. The main issue is that android browsers doesn't support Speech Recognition and Speech synthesis also, as shown in the android captured image below: (you have to manualy paste it in browser because i am not allowed to post urls)
