Android 在实现 RecognitionListener 时获得意图

正如Iftah在回答中所述,我可以通过将Uri从意图传递给以下位置来获得Android中语音Recoginition录制的音频:

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    // the recording url is in getData:
    Uri audioUri = data.getData();
}

在这里,正是我想要的,没有问题。Intent data

一切都很完美,但是该解决方案为用户提供了何时说话的提示,我不想这样做,所以为了解决这个问题,我让我的活动实现RefisionListener,如下所示:

public class MainActivity extends AppCompatActivity implements RecognitionListener {

    private SpeechRecognizer speech = null;
    private Intent recognizerIntent;

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

        recognizerIntent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
        recognizerIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, "sv_SE");
        recognizerIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_PREFERENCE, "sv_SE");
        recognizerIntent.putExtra("android.speech.extra.GET_AUDIO_FORMAT", "audio/AMR");
        recognizerIntent.putExtra("android.speech.extra.GET_AUDIO", true);

        speech = SpeechRecognizer.createSpeechRecognizer(this);
        speech.setRecognitionListener(this);
        speech.startListening(recognizerIntent);
    }

    @Override
    public void onReadyForSpeech(Bundle params) {
        Log.d("Debug", "On ready for speech");
    }

    @Override
    public void onBeginningOfSpeech() {
        Log.d("Debug", "On beggining of speech");
    }

    @Override
    public void onRmsChanged(float rmsdB) {
        Log.d("Debug", "Rsm changed");
    }

    @Override
    public void onBufferReceived(byte[] buffer) {
        Log.d("Debug", "Buffer recieved");
    }

    @Override
    public void onEndOfSpeech() {
        Log.d("Debug", "On end of speech");
    }

    @Override
    public void onError(int error) {
        Log.d("Debug", "Error");
    }

    @Override
    public void onPartialResults(Bundle partialResults) {
        Log.d("Debug", "On partial result");
    }

    @Override
    public void onEvent(int eventType, Bundle params) {
        Log.d("Debug", "On event");
    }

    @Override
    public void onResults(Bundle results) {
        Log.d("Debug", "On result");
    }
}

这绕过了提示hovewer,我无法弄清楚如何像第一个示例中那样获取Uri,因为这里:

@Override
    public void onResults(Bundle results) {
        Log.d("Debug", "On result");
        // The results bundle don't contain the URI!
    }

我得到一个不包含意图或Uri的。我尝试过查看捆绑包中的所有密钥,并且没有URI或意图存在,我也尝试过,但这不会返回任何内容。Bundle resultsgetIntent()

我感谢任何帮助或朝着正确的方向前进。

结果应位于具有 键 的捆绑包中。SpeechRecognizer.RESULTS_RECOGNITION

@Override
public void onResults(Bundle results) {
    if (results != null && results.containsKey(SpeechRecognizer.RESULTS_RECOGNITION)) {
      List<String> resultsList = results.getStringArrayList(SpeechRecognizer.RESULTS_RECOGNITION);
      // most likely result is resultsList.get(0)
    } else {
      // no results
    }

}

请参阅 Android 开发人员文档,了解 SpeechRecognizer 对此进行了详细解释。这种用于获取语音识别结果的方法也适用于#onPartialResults
