我正在尝试在Google Glass中创建一个功能,该功能允许我在卡片之间进行导航,而不必说“ ok glass”这个热门字词。

我尝试创建了一个SpeechRecognizer,它将不断地监听是否在说什么,或者是否提到了正确的“命令”,该应用将相应地起作用。

但是onError方法告诉我

Error occured: RecognitionService busy.


并抛出一个错误,说

我目前正在使用该项目来测试我希望在最终应用程序中具有的某些功能。目前我正在使用


头部手势导航
现场直播卡和沉浸式游戏的结合
使用shell命令以便simulate touch gestures的类


这是我为SpeechRecognizer写的课程

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MainActivity onCreate()方法中调用此类。

private SpeechDetector mSpeechDetector;

@Override
protected void onCreate(Bundle bundle) {
    super.onCreate(bundle);

    mIssueKey = new issueKey();
    mSpeechDetector = new SpeechDetector(getApplicationContext());


我变了

new SpeechDetector(MainActivity.this);




new SpeechDetector(getApplicationContext());


而且我不再收到泄漏的错误

然而

显然,泄漏的错误与RecognitionService繁忙无关。
所以我仍然坚持我的语音识别不起作用,因为它会引发RecognitionService busy错误

编辑
我只是注意到它写了一个额外的日志

    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

最佳答案

您调用RecognitionService时,似乎已经在使用startListening()。我相信这是因为您已经在构造函数中调用了startListening(),然后在onEndOfSpeech()中再次调用了它。

确保在再次调用cancel()之前进行必要的startListening()调用。
