대화 상자를 표시하지 않고 안드로이드의 음성 인식을 사용할 수 있습니까?

Question

안드로이드에서 텍스트 API에 연설을 사용하고 싶지만 대화 상자에서 속도를 늦추고 싶지는 않습니다. 그것들없이 기능을 사용할 수 있습니까?

Answer 1

음성 인식에 대한 제

The Intent 대화 상자를 표시하고 그것을 보여주는 해제하는 옵션은 없습니다.

음성 인식 기능을 사용하려면 인식을 위해 소리를 Google에 업로드 할 수 있도록 인터넷에 연결되어 있어야합니다.

Answer 2

예 가능 :

API의 SpeechRecognizer 클래스를 사용할 수 있습니다. API에 따라 필요에 따라 주 스레드에서 사용되는지, 클래스가 RecognitionListener를 구현하는지 확인하십시오.

private SpeechRecognizer speech; 

@Override 
public void onCreate(Bundle savedInstanceState) 
{ 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main); 

    speech = SpeechRecognizer.createSpeechRecognizer(this); 
    speech.setRecognitionListener(this); 

    Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH); 
    intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_PREFERENCE, "en"); 
    intent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE, 
     this.getPackageName()); 

    speech.startListening(intent); 
} 

@Override 
public void onBeginningOfSpeech() 
{ 
} 

@Override 
public void onBufferReceived(byte[] arg0) 
{ 
} 

@Override 
public void onEndOfSpeech() 
{ 
} 

@Override 
public void onError(int e) 
{ 
} 

@Override 
public void onEvent(int arg0, Bundle arg1) 
{ 
} 

@Override 
public void onPartialResults(Bundle arg0) 
{ 
} 

@Override 
public void onReadyForSpeech(Bundle arg0) 
{ 
} 

@Override 
public void onResults(Bundle data) 
{ 
    ArrayList<String> matches = data.getStringArrayList(
     SpeechRecognizer.RESULTS_RECOGNITION); 

    // Do something useful with the matches =) 
    // ... 
} 

@Override 
public void onRmsChanged(float arg0) 
{ 
}
