Question

我将尝试在没有带有RecognitionListener的Google对话框的情况下使用语音识别但是在启动应用程序时只能发出蜂鸣声。我已将权限音频记录和Internet添加到清单文件中。我希望你告诉我并帮我找错...我没有错误的日志猫...我当用户说出问候语时，我想做一个循环.Toast显示一个消息，然后一个列表视图显示结果。

 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) { }

  }

Answer 2

你错过了：

mSpeechRecognizer.setRecognitionListener();

该参数可以是实现侦听器的上下文，也可以是您创建的自定义侦听器。

目前您的代码未设置侦听器，您只需拥有侦听器代码。

编辑：如果您没有实施RecognitionListener，那么您可以这样做：

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

                                }

                            });
