是否可以在Google Glass上安裝Android語音識別（作爲自定義服務）？

我們有一個運行語音識別作爲服務的演示Android應用程序（Android 4.0.3），並且（連續地）在視圖上記錄識別結果。是否可以在Google Glass上安裝Android語音識別（作爲自定義服務）？

在我們的智能手機中，一切正常。

我們想在谷歌眼鏡浸泡應用程序複製這種情況下，但是，當我們嘗試啓動該服務，我們總是有這樣的錯誤消息：

沒有選擇的語音識別服務

是否有一些已知的限制？或者有人想出瞭如何解決這類問題？提前

由於這是活動的一些顯著代碼：

public class MainActivity extends Activity implements Observer { 
    ... 
    @Override 
    protected void onStart() { 
     super.onStart(); 
     //Toast.makeText(this, "Hi guys", Toast.LENGTH_LONG); 
     startService(new Intent(this, SilentVoiceRecognitionService.class)); 
    } 
    ... 
}

這是服務的代碼：

public class SilentVoiceRecognitionService extends Service { 
    protected AudioManager mAudioManager; 
    protected SpeechRecognizer mSpeechRecognizer; 
    protected Intent mSpeechRecognizerIntent; 
    protected final Messenger mServerMessenger = new Messenger(new IncomingHandler(this)); 

    private Model model = Model.getInstance(); 

    static final String TAG = "SilentRecognizer"; 
    static final int MSG_RECOGNIZER_START_LISTENING = 1; 
    static final int MSG_RECOGNIZER_CANCEL = 2; 

    protected boolean mIsListening; 

    @Override 
    public void onCreate() 
    { 
     super.onCreate(); 
     mSpeechRecognizer = SpeechRecognizer.createSpeechRecognizer(this); 
     mSpeechRecognizer.setRecognitionListener(new SpeechRecognitionListener()); 
     mSpeechRecognizerIntent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH); 
     mSpeechRecognizerIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, 
            RecognizerIntent.LANGUAGE_MODEL_FREE_FORM); 
     mSpeechRecognizerIntent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE, 
            this.getPackageName()); 
    } 

    @Override 
    public int onStartCommand(Intent intent, int flags, int startId) { 
     Log.i("LocalService", "Received start id " + startId + ": " + intent); 
     // We want this service to continue running until it is explicitly 
     // stopped, so return sticky. 

     mSpeechRecognizer.startListening(mSpeechRecognizerIntent); 

     return START_STICKY; 
    } 

    @Override 
    public void onDestroy() 
    { 
     super.onDestroy(); 

     if (mSpeechRecognizer != null) 
     { 
      mSpeechRecognizer.destroy(); 
     } 
    } 

    protected class SpeechRecognitionListener implements RecognitionListener 
    { 

     ... 
    } 


    protected static class IncomingHandler extends Handler 
    { 
     private WeakReference<SilentVoiceRecognitionService> mtarget; 

     IncomingHandler(SilentVoiceRecognitionService target) 
     { 
      mtarget = new WeakReference<SilentVoiceRecognitionService>(target); 
     } 


     @Override 
     public void handleMessage(Message msg) 
     { 
      final SilentVoiceRecognitionService target = mtarget.get(); 

      switch (msg.what) 
      { 
       case MSG_RECOGNIZER_START_LISTENING: 

        if (!target.mIsListening) 
        { 
        target.mSpeechRecognizer.startListening(target.mSpeechRecognizerIntent); 
         target.mIsListening = true; 
         //Log.d(TAG, "message start listening"); //$NON-NLS-1$ 
        } 
        break; 

       case MSG_RECOGNIZER_CANCEL: 
        target.mSpeechRecognizer.cancel(); 
        target.mIsListening = false; 
        //Log.d(TAG, "message canceled recognizer"); //$NON-NLS-1$ 
        break; 
      } 
     } 
    }

}

您是否在應用程序的清單中添加了用戶權限標記？ –

確定：<使用權限android：name =「android.permission.RECORD_AUDIO」/> –

此外，現在是否有可能擁有一副眼鏡？好的，忘記了。我認爲語音識別在GG中的工作方式有點不同。請參閱[這裏]（https://developers.google.com/glass/develop/gdk/input/voice）。 –
