Android语音识别权限不足(错误码9)

Question

我正在尝试在没有标准对话的情况下实现语音识别(它在对话中运行良好)。

我一尝试开始收听就收到错误代码 9。

我的设备是 LG G Stylo(运行 Android 6.0)。

list :

<manifest package="example.com.myapplication"
      xmlns:android="http://schemas.android.com/apk/res/android">
<uses-permission android:name="android.permission.RECORD_AUDIO"/>
<application
 .....

(也尝试添加 INTERNET 权限，尽管这不是必需的，因为离线识别应该有效)

build.gradle:

compileSdkVersion 23
buildToolsVersion "23.0.2"

defaultConfig {
    applicationId "example.com.appname"
    minSdkVersion 19
    targetSdkVersion 23
    versionCode 1
    versionName "1.0"
}

语音识别代码:

private SpeechRecognizer speechRecognizer;

protected void onCreate(Bundle savedInstanceState) {
  speechRecognizer = SpeechRecognizer.createSpeechRecognizer(this);
  speechRecognizer.setRecognitionListener(new speech_listener());
  Intent intent = new intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
  intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
     RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
  intent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE,
       getApplication().getPackageName());
  intent.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS, 1);
  intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, Locale.ENGLISH);
  speechRecognizer.startListening(intent);

监听器(内部)类:

class speech_listener implements RecognitionListener
{
  public void onReadyForSpeech(Bundle params){}
  public void onBeginningOfSpeech(){}
  public void onRmsChanged(float rmsdB){}
  public void onBufferReceived(byte[] buffer){}
  public void onEndOfSpeech(){}
  public void onError(int error){
    Log.d("Speech", "error: " + error);
  }
  public void onResults(Bundle results)
  {
    ArrayList data = results.getStringArrayList(SpeechRecognizer.RESULTS_RECOGNITION);
    String answer = (String)data.get(0);
    processAnswer(answer);
  }
  public void onPartialResults(Bundle partialResults){}
  public void onEvent(int eventType, Bundle params){}
}

如有任何见解，我们将不胜感激。

在 Android 6 上，此权限是危险权限之一，这意味着您需要要求用户确认(实际获取)。检查this和 this了解更多详情。
