and this another response from them:
I just did a little test to see if the speech recognition engine is available in either Crosswalk 7 (which is based off of Chromium 36) or the Android 4.4 webview (which is based off Chrome 30). The demo app here: and the documentation indicate that you need Chrome 25 or greater.
However, as you can see from the tests below, the speech recognition library is not present in either of these. This is something that is unique to Chrome desktop and Chrome mobile. It is not, however, available in either the Crosswalk webview or the Android 4.4 webview (and definitely not in the older Android webviews).
The only way you're going to be able to use your Construct2 media object along with speech recognition is if the Construct2 folks provide the appropriate hooks for that feature as part of their library for Cordova webviews. This is not something that we can enable for you in the XDK, this is something the Construct2 engine needs to do. The most likely scenario is that they would use a Cordova plugin to provide the necessary speech recognition.
Chrome webview in Android 4.4:
Chrome webview in Crosswalk 7:
so can you provide this feature in construct 2?
