UPDATE: The below function you used to detect connection determines if it is connected to network and it does not determine you have internet access on the connected network.However that does not appear to be problem in your case, experiment with google speech recogniser and see if the same problem occurs,Needs some more info to provide you a solution

web socket connections are designed to disconnect when there is no network.Please make sure you have active internet connection or you probably didnt add <uses-permission android:name="android.permission.INTERNET" /> to manifest.

i did add the permission and the device is connected, also tested the connection status from code : '

 private void checknetwork(){
    ConnectivityManager cm = (ConnectivityManager)BingTest.this.getSystemService(Context.CONNECTIVITY_SERVICE);

    NetworkInfo activeNetwork = cm.getActiveNetworkInfo();
    boolean isConnected = activeNetwork != null &&

        Log.i(TAG, "Device is Connected ++++++++++++ ");
        Log.i(TAG, "Device is Not Connected ----------+ ");

Are you using this sample?

if that is correct:

Since September Microsoft has a new Speech related Cognitive Services SDK:

We released a new Speech SDK supporting the new Unified Speech Service. The new Speech SDK comes with support for Windows, Android, Linux, Javascript and iOS.

Please check out Microsoft Cognitive Services Speech SDK for documentation (, links to the download pages, and the samples.
