我試圖讓我的Android 2.3.3應用程序的語音識別工作,但缺少一些基本的東西。Android正在忽略RECORD_AUDIO權限和語音API實施
首先,我AndroidManifest.xml
文件的頂部,我有:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.myuser.myapp">
<uses-permission android:name="android.permission.RECORD_AUDIO" />
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
... remainder omitted for brevity
其中我相信應促使Android的詢問最終用戶是否要授予我的應用程序權限的話筒時,它啓動(如果沒有,請糾正我!)...
接下來,我有Activity
,其中有我的應用程序的語音識別功能的整個需要。基本上,我希望應用程序來檢測每當有人說出聲來,「轉到」:
public class SpeechActivity extends AppCompatActivity implements RecognitionListener {
private SpeechRecognizer speechRecognizer;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_speech);
int check = ContextCompat.checkSelfPermission(this, android.Manifest.permission.RECORD_AUDIO);
if(check != PackageManager.PERMISSION_GRANTED) {
throw new RuntimeException("Ya can't do that now, ya here.");
}
speechRecognizer = SpeechRecognizer.createSpeechRecognizer(this);
speechRecognizer.setRecognitionListener(this);
Intent speechIntent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
speechIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
speechIntent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE, "voice.recognition.test");
speechIntent.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS, 5);
speechRecognizer.startListening(speechIntent);
Log.i("SpeechActivity", "Speech Recognizer is listening");
}
@Override
public void onReadyForSpeech(Bundle bundle) {
}
@Override
public void onBeginningOfSpeech() {
}
@Override
public void onRmsChanged(float v) {
}
@Override
public void onBufferReceived(byte[] bytes) {
}
@Override
public void onEndOfSpeech() {
}
@Override
public void onError(int i) {
}
@Override
public void onResults(Bundle bundle) {
Log.i("SpeechActivity", "Speech was detected...");
String spoken = "";
ArrayList<String> data = bundle.getStringArrayList(SpeechRecognizer.RESULTS_RECOGNITION);
for (int i = 0; i < data.size(); i++) {
spoken += data.get(i);
}
Log.i(this.getClass().getName(), String.format("The word \"%s\" was detected.", spoken));
if(spoken.equalsIgnoreCase("go")) {
doSomething();
}
}
@Override
public void onPartialResults(Bundle bundle) {
}
@Override
public void onEvent(int i, Bundle bundle) {
}
}
我通過(通過USB)我的手機連接到我的筆記本電腦上運行我的三星Galaxy S7邊緣應用,點擊Android Studio中的運行(app)按鈕,然後選擇我的手機作爲連接的設備。
當應用程序在我的手機上啓動時,我注意到的第一件事是它不會提示我接受/拒絕應用程序使用麥克風的權限。這是一個預警信號,告訴我有什麼東西是錯誤的。
但是,當我瀏覽到SpeechActivity/activity_speech.xml
屏幕,我得到:
在運行此我得到:

是否有可能我需要下載和安裝,以插件或APK讓語音識別工作?爲什麼我的應用程序沒有要求使用手機麥克風的權限?語音識別器是如何開始/聆聽的,但似乎沒有聽到任何演講?
聲明清單中的權限是Mashmallow之前的方式,因爲您需要通過權限詢問用戶權限,以便在屏幕上顯示提示。你應該檢查這個鏈接:https://developer.android.com/training/permissions/requesting.html – vincenth
