Question

我正在使用GDK偷看来构建应用程序，并且无法在沉浸式应用程序中使用语音识别功能。这是我的第一个android项目。

我试图遵循这个：How can I use speech recognition without the annoying dialog in android phones

在初步进展之后，我遇到了一个问题，其中RecognitionListener类抛出错误9，权限不足。

我使用的是GDK，即Android-15。

识别器的初始化在我的onCreate（）方法中：

sr = SpeechRecognizer.createSpeechRecognizer(this);       
sr.setRecognitionListener(new listener());

当我收到一个轻敲回叫时，我开始听：

private GestureDetector createGestureDetector(Context context) {
        GestureDetector gestureDetector = new GestureDetector(context);
        //Create a base listener for generic gestures
        gestureDetector.setBaseListener( new GestureDetector.BaseListener() {
            @Override
            public boolean onGesture(Gesture gesture) {
//              Log.info(gesture.name());
                if (gesture == Gesture.TAP) {
                    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,"voice.recognition.test");

                    intent.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS,5); 
                    sr.startListening(intent);
                    return true;
                }
                return false;
            }
        });

        return gestureDetector;
    }

这是我的监听器类的定义：

class listener implements RecognitionListener          
    {
        public void onReadyForSpeech(Bundle params)
        {
            Log.d(TAG, "onReadyForSpeech");
        }
        public void onBeginningOfSpeech()
        {
             Log.d(TAG, "onBeginningOfSpeech");
        }
        public void onRmsChanged(float rmsdB)
        {
             Log.d(TAG, "onRmsChanged");
        }
        public void onBufferReceived(byte[] buffer)
        {
             Log.d(TAG, "onBufferReceived");
        }
        public void onEndOfSpeech()
        {
             Log.d(TAG, "onEndofSpeech");
        }
        public void onError(int error)
        {
             Log.d(TAG,  "error " +  error);
//               mText.setText("error " + error);
        }
        public void onResults(Bundle results)                   
        {
             String str = new String();
             Log.d(TAG, "onResults " + results);
             ArrayList<String> data = results.getStringArrayList(SpeechRecognizer.RESULTS_RECOGNITION);
             for (int i = 0; i < data.size(); i++)
             {
                       Log.d(TAG, "result " + data.get(i));
                       str += data.get(i);
             }
//               mText.setText("results: "+String.valueOf(data.size()));        
        }
        public void onPartialResults(Bundle partialResults)
        {
             Log.d(TAG, "onPartialResults");
        }
        public void onEvent(int eventType, Bundle params)
        {
             Log.d(TAG, "onEvent " + eventType);
        }
    }

这是我的清单文件：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.medicalglass"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="15"
        android:targetSdkVersion="15" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name="com.example.medicalglass.MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

在触摸事件进入并且我调用start listen之后，立即调用侦听器的onError方法，错误代码为9，表示权限不足。如果有人有任何android语音命令或玻璃语音命令的经验，并知道为什么这会继续失败，我将非常感激。感谢。

Answer 1

首先更改此代码：

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,"voice.recognition.test");

到此代码：

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());
speechRecognizer.startListening(intent);

编辑：将此添加到您的清单：

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

如果您有错误，请通过您的LogCat。

Answer 2

现在应该使用API级别19和上面提到的两个权限。

Answer 3

语音识别无法离线使用（但？），请参阅此Google Glass请求的功能，以允许离线语音识别（Issue 305）

Answer 4

您必须请求从Android M开始的许可。

 if (ContextCompat.checkSelfPermission(activity, Manifest.permission.READ_CONTACTS) == PackageManager.PERMISSION_GRANTED && ContextCompat.checkSelfPermission(activity, Manifest.permission.GET_ACCOUNTS) == PackageManager.PERMISSION_GRANTED)
                    return;
                else {
                    if (ActivityCompat.shouldShowRequestPermissionRationale(activity, Manifest.permission.RECORD_AUDIO)) {
                        Toast.makeText(activity, "Record audio is required", Toast.LENGTH_LONG).show();
                    } else {
                        ActivityCompat.requestPermissions(activity, new String[]{Manifest.permission.RECORD_AUDIO}, RECORD_AUDIO);
                    }
                }

SpeechRecognizer与Glass的权限不足错误
