Question

如this answer by Iftah中所述，我可以通过将Uri从意图传递到以下内容来获取Android中语音识别记录的音频：

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

这里Intent data正是我想要的，没有问题。

这一切都完美无缺，但是该解决方案为用户提示何时发言，我不希望如此绕过我让我的活动实现RecognitionListener：

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，我无法弄清楚如何在第一个例子中得到Uri，因为这里：

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

我得到的Bundle results不包含Intent或Uri。我已经尝试查看捆绑中的所有密钥，并且没有URI或Intent存在，我也尝试过getIntent()但是没有返回任何内容。

我感谢任何帮助或推动正确的方向。

结果应该与密钥SpeechRecognizer.RESULTS_RECOGNITION捆绑在一起。

@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
    }

}

有关SpeechRecognizer的详细信息，请参阅Android开发人员文档。这种获取语音识别结果的方法也适用于#onPartialResults
