java - 使用 SpeechRecognizer 获取已识别数据的转录

Question

我使用 SpeechRecognizer 来实现“语音到文本”功能，她的工作结果是文本数据:

Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, 
RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);                
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, Locale.US.toString());
intent.putExtra("android.speech.extra.EXTRA_ADDITIONAL_LANGUAGES", new String[]{});
SpeechRecognizer recognizer = SpeechRecognizer.createSpeechRecognizer(getApplicationContext());
recognizer.setRecognitionListener(new RecognitionListener() {
  @Override
  public void onReadyForSpeech(Bundle params) {}

  @Override
  public void onBeginningOfSpeech() {}  

  @Override
  public void onRmsChanged(float rmsdB) {}

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

  @Override
  public void onEndOfSpeech() {}

  @Override
  public void onError(int error) {}

  @Override
  public void onPartialResults(Bundle partialResults) {}

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

  @Override
  public void onResults(Bundle results) {
    String result = null;
    ArrayList<String> arrOfResults = results.getStringArrayList(SpeechRecognizer.RESULTS_RECOGNITION);
    String command = arrOfResults.get(0);
  }
});
recognizer.startListening(intent);  

是否可以使用此方法获得已识别语音而不是文本的转录？
例如，它在 Google 翻译中实现:

或者，如有必要，请使用不同的方法。

我该怎么做？提前致谢。问候...

SpeechReocgnizer API 仅提供“文本”(我猜是正常的正字法文本)，以及可选的置信度分数，请参阅:https://developer.android.com/reference/android/speech/RecognitionListener.html#onResults(android.os.Bundle)
