Recording audio to a file during speech recognition

Question

Is there a way to record sound from a Windows Phone microphone while speech recognition is still on?

When I try to do this, the speech recognition request blocks the application, and therefore, the recorder never starts while recognition is in progress.

var speechRecognizer = new SpeechRecognizer();
function startMediaCaptureSession() {
    Windows.Storage.ApplicationData.current.localFolder.createFileAsync("audio.mp3", Windows.Storage.CreationCollisionOption.generateUniqueName).then(function (newFile) {
       oMediaCapture.startRecordToStorageFileAsync(profile,newFile).then(function (result) {                            
           speechRecognizer.recognizeAsync();
       }, errorHandler);
    }  );   
}

Is there any way to do this?
