 SFSpeechRecognizerAuthorizationStatus speechAuthStatus = [SFSpeechRecognizer authorizationStatus];
 if (speechAuthStatus == SFSpeechRecognizerAuthorizationStatusNotDetermined) {
  [SFSpeechRecognizer requestAuthorization:^(SFSpeechRecognizerAuthorizationStatus status) {
   if (status == SFSpeechRecognizerAuthorizationStatusAuthorized) {
    dispatch_async(dispatch_get_main_queue(), ^{
     if (returnBlock) {
      returnBlock(YES);
     }
    });
   } else {
    dispatch_async(dispatch_get_main_queue(), ^{
     if (returnBlock) {
      returnBlock(YES);
     }
