我试图在谷歌眼镜中创建一个功能，允许我在卡片之间进行导航，而无需说出“ok glass”这个热门词汇。
我试着创建一个SpeechRecognizer，它会不断地侦听是否有人在说什么，如果提到正确的“命令”，应用程序将会相应地执行。
然而，onError方法告诉我
Error occured: RecognitionService busy.
和它抛出，说
Activity com.example.sw_stage.topfinder.MainActivity has leaked ServiceConnection [email protected] that was originally bound here

我目前使用这个项目来测试一些我想有功能的错误我最终申请。目前我使用
- 头部姿势导航
- 活卡和浸泡
- 为了使用shell命令的类simulate touch gestures
这里组合为I类写了SpeechRecognizer
package com.example.sw_stage.topfinder;
import android.content.Context;
import android.content.Intent;
import android.media.AudioManager;
import android.os.Bundle;
import android.speech.RecognitionListener;
import android.speech.RecognizerIntent;
import android.speech.SpeechRecognizer;
import android.util.Log;
import java.util.ArrayList;
public class SpeechDetector {
AudioManager mAudioManager;
SpeechRecognizer mSpeechRecognizer;
Intent intent;
issueKey mIssueKey = new issueKey();
public SpeechDetector(Context context)
{
Log.i("speechdetector", "calling speech detector");
mAudioManager = (AudioManager) context.getSystemService(Context.AUDIO_SERVICE);
mSpeechRecognizer = SpeechRecognizer.createSpeechRecognizer(context);
mSpeechRecognizer.setRecognitionListener(new listener(context));
intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
Log.i("package name", context.getPackageName());
intent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE, context.getPackageName());
mSpeechRecognizer.startListening(intent);
Log.i("111111","11111111"+"in");
}
class listener implements RecognitionListener
{
Context context1;
public listener(Context context)
{
context1 = context;
}
@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() {
mSpeechRecognizer.startListening(intent);
}
@Override
public void onError(int i) {
//3 Audio recording error.
//5 Other client side errors.
//6 - No speech input
//7 -No recognition result matched.
//8 RecognitionService busy.
//9 - vInsufficient permissions
if(i == 1 || i == 2 || i == 3 || i == 4 || i == 5 || i == 6 || i == 7 || i == 8 || i == 9)
{
Log.wtf("Error occured", "Error " + i);
mSpeechRecognizer.startListening(intent);
}
}
@Override
public void onResults(Bundle bundle) {
ArrayList data = bundle.getStringArrayList(SpeechRecognizer.RESULTS_RECOGNITION);
String result = "enter";
String reslt = "";
for (int i = 0; i < data.size(); i++)
{
reslt = reslt + " " + data.get(i);
}
switch(result)
{
case "next": mIssueKey.issueKey(22);
break;
case "previous": mIssueKey.issueKey(21);
break;
case "enter": mIssueKey.issueKey(23);
break;
case "leave": mIssueKey.issueKey(4);
}
}
@Override
public void onPartialResults(Bundle bundle) {
}
@Override
public void onEvent(int i, Bundle bundle) {
}
}
}
我在我的MainActivity onCreate（）方法中调用这个类。
private SpeechDetector mSpeechDetector;
@Override
protected void onCreate(Bundle bundle) {
super.onCreate(bundle);
mIssueKey = new issueKey();
mSpeechDetector = new SpeechDetector(getApplicationContext());
我改变
new SpeechDetector(MainActivity.this);
到
new SpeechDetector(getApplicationContext());
，我不得到泄露的错误了
无论其
显然泄漏错误和RecognitionService忙不相关。 所以我还是坚持了这样的事实，我的语音识别不起作用，因为它抛出一个RecognitionService busy错误
编辑 我只注意到它写入附加日志
03-03 13:11:13.252 20018-20018/? A/Error occured﹕ RecognitionService busy
03-03 13:11:13.260 825-825/? I/RecognitionService﹕ concurrent startListening received - ignoring this call
在你的MainActivity中，你有没有把你的'SpeechDetector'类实例声明为'static'？ – 2015-03-03 10:07:54
@ZygoteInit没有声明为静态。我只是用SpeechDetector类的声明和调用更新了我的代码 – NoSixties 2015-03-03 10:14:36
您是否需要服务始终运行或者仅与活动生命有关，如果它只在活动生命中有效，则停止并取消注册暂停或停止方法。 – 2015-03-03 11:03:18
