語音識別

我將嘗試使用谷歌沒有對話框中的語音識別與RecognitionListener 但不啓動時的application.I只能發出蜂鳴聲已添加權限音頻記錄和互聯網進入清單file.I希望你告訴我，幫我找錯了......我還沒有錯誤日誌上的貓......我想打一個循環，當用戶問好舉杯顯示了mesage Regognition OK和列表視圖中顯示結果。語音識別

public class MainActivity extends Activity implements RecognitionListener 
{ 

private ListView wordsList; 

private SpeechRecognizer mSpeechRecognizer; 
private Intent mSpeechRecognizerIntent; 


protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 

    mSpeechRecognizer = SpeechRecognizer.createSpeechRecognizer(this); 
    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()); 

    wordsList = (ListView) findViewById(R.id.listView1); 

    mSpeechRecognizer.startListening(mSpeechRecognizerIntent); 

} 


    public void onBeginningOfSpeech(){ } 

     public void onBufferReceived(byte[] buffer){ } 

     public void onEndOfSpeech(){ } 

     public void onError(int error){ 

      //mSpeechRecognizer.startListening(mSpeechRecognizerIntent); 

    } 

    public void onEvent(int eventType, Bundle params){ } 


    public void onPartialResults(Bundle partialResults){ } 


    public void onReadyForSpeech(Bundle params){ 


     Toast.makeText(getBaseContext(), "Voice recording starts", Toast.LENGTH_SHORT).show(); 

    } 

    public void onResults(Bundle results) 
    { 

     ArrayList<String> matches = results.getStringArrayList(SpeechRecognizer.RESULTS_RECOGNITION); 


     wordsList.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, matches)); 


     if (matches.contains("hello") { 

      Toast.makeText(getBaseContext(), "Recognision OK!!!", Toast.LENGTH_SHORT).show(); 

      } 

    } 

    public void onRmsChanged(float rmsdB) { }

嘗試在onResult中使用matches.get（0） – Meenal

我不認爲這是問題...因爲在演講開始時不顯示Toast「錄音開始」......我使用Samsung S4。 .. – user2342687

你已經錯過了：

mSpeechRecognizer.setRecognitionListener();

的參數將是要麼是其實現監聽，或你所創建的自定義偵聽範圍內。

目前你的代碼沒有設置監聽器，你只需要監聽的代碼。

編輯：如果你不執行RecognitionListener，那麼你可以這樣來做：

mSpeechRecognizer.setRecognitionListener(new RecognitionListener() { 

           @Override 
           public void onBeginningOfSpeech() { 
            // TODO Auto-generated method stub 

           } 

           @Override 
           public void onBufferReceived(byte[] arg0) { 
            // TODO Auto-generated method stub 

           } 

           @Override 
           public void onEndOfSpeech() { 
            // TODO Auto-generated method stub 

           } 

           @Override 
           public void onError(int arg0) { 
            // TODO Auto-generated method stub 

           } 

           @Override 
           public void onEvent(int arg0, Bundle arg1) { 
            // TODO Auto-generated method stub 

           } 

           @Override 
           public void onPartialResults(Bundle partialResults) { 
            // TODO Auto-generated method stub 

           } 

           @Override 
           public void onReadyForSpeech(Bundle params) { 
            // TODO Auto-generated method stub 

           } 

           @Override 
           public void onResults(Bundle results) { 
            // TODO Auto-generated method stub 

           } 

           @Override 
           public void onRmsChanged(float rmsdB) { 
            // TODO Auto-generated method stub 

           }

好mSpeechRecognizer.setRecognitionListener（聽者）;我必須爲聽衆提供什麼？ – user2342687

由於您的代碼'實現了RecognitionListener'，我認爲'this'將是正確的用法。我會編輯我的答案以另一種方式顯示。 – brandall

Ok works mSpeechRecognizer.setRecognitionListener（this）;非常感謝你！！！！！！！！！！！ – user2342687

很棒的答案。在android 6中，在使用語音API之前，需要權限'Manifest.permission.RECORD_AUDIO' –
