我从互联网上复制了这个,其他人说这是有效的,但是当我尝试的时候 说它没有做任何事情。

我尝试在方法onBeginingOfSpeech()之外编写有关意图的代码,但它确实有效。

public class Schermata extends ActionBarActivity implements RecognitionListener{

    SpeechRecognizer speechRecognizer;
    TextView test;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_schermata);
        speechRecognizer = SpeechRecognizer.createSpeechRecognizer(this);
        test = (TextView) findViewById(R.id.test);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_schermata, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();

        //noinspection SimplifiableIfStatement
        if (id == R.id.action_settings) {
            return true;
        }

        return super.onOptionsItemSelected(item);
    }

    @Override
    public void onReadyForSpeech(Bundle params) {
        test.setText("INIZIO");

    }

    @Override
    public void onBeginningOfSpeech() {
        test.setText("INIZIO");
        Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
        intent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE,getClass().getPackage().getName());
        intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
        speechRecognizer.startListening(intent);

    }

    @Override
    public void onRmsChanged(float rmsdB) {

    }

    @Override
    public void onBufferReceived(byte[] buffer) {

    }

    @Override
    public void onEndOfSpeech() {
        test.setText("FINE");
    }

    @Override
    public void onError(int error) {

    }

    @Override
    public void onResults(Bundle results) {
        ArrayList<String> res = results.getStringArrayList(SpeechRecognizer.RESULTS_RECOGNITION);
        String s = "";
        for (String result : res)
            s += result + "\n";
        test.setText(s);
    }

    @Override
    public void onPartialResults(Bundle partialResults) {

    }

    @Override
    public void onEvent(int eventType, Bundle params) {

    }
}

如果我理解正确,当在onBeginningOfSpeech()之外定义Intent时,这对你有用,那么简单地把它放在它之外,把它放在那里是错误的,我会解释。

函数onBeginningOfSpeech()(另外:onResults,onReadyForSpeech等等)在识别器开始工作后被调用,并且只是识别器听到人说话的事件的回调,所以你需要有在调用此函数之前,意图准备就绪并与识别器配对。

尝试创建一个'initialize()'函数,在调用

之前设置所有这些函数
speechRecognizer.startListening(intent);

换句话说,使用它,而不是'onBeginningOfSpeech()'上的内容

 public void initialize(){
    Intent intent = new   Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
    intent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE,getClass().getPackage().getName());
    intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
    speechRecognizer.startListening(intent);
}

除此之外,你正在以错误的方式使用onResults(),你应该只提取给你的ArrayList的第一个String,其他的只是同一个语音的最差结果。

<uses-permission android:name="android.permission.RECORD_AUDIO" />

确保清单中有RECORD_AUDIO权限,语音识别在没有它的情况下不起作用。
