Android的SpeechRecognizer网络错误 [英] Android SpeechRecognizer Network Error
问题描述
我想在Android 4.4系统来创建一个连续语音识别，简单的在一个TextView显示所说的话，就像是听写。我也跟着多教程，像<一个href=\"https://github.com/fcrisciani/android-speech-recognition/blob/master/VoiceRecognition/src/com/speech/fcrisciani/voicerecognition/ContinuousDictationFragment.java\" rel=\"nofollow\">https://github.com/fcrisciani/android-speech-recognition/blob/master/VoiceRecognition/src/com/speech/fcrisciani/voicerecognition/ContinuousDictationFragment.java,或<一个href=\"http://stackoverflow.com/questions/4975443/is-there-a-way-to-use-the-speechrecognizer-api-directly-for-speech-input\">Is有没有直接使用SpeechRecognizer API将语音输入，并实施了以下版本的方法：
I'm trying to create a continous speech recognition in Android 4.4, simple displaying the spoken words in a TextView, like a dictate. I followed multiple tutorials, like https://github.com/fcrisciani/android-speech-recognition/blob/master/VoiceRecognition/src/com/speech/fcrisciani/voicerecognition/ContinuousDictationFragment.java, or Is there a way to use the SpeechRecognizer API directly for speech input? and implemented the following version:
import java.util.ArrayList;
import android.app.Activity;
import android.content.Intent;
import android.graphics.PorterDuff;
import android.os.Bundle;
import android.speech.RecognitionListener;
import android.speech.RecognizerIntent;
import android.speech.SpeechRecognizer;
import android.view.KeyEvent;
import android.view.View;
import android.widget.ImageButton;
import android.widget.TextView;
public class VoiceReadActivity extends Activity {
private ImageButton mButtonSpeech;
private TextView mTextView;
private SpeechRecognizer mSpeechRecognizer = null;
private SpeechRecognizer getSpeechRecognizer() {
if (mSpeechRecognizer == null) {
mSpeechRecognizer = SpeechRecognizer.createSpeechRecognizer(this);
mSpeechRecognizer.setRecognitionListener(new RecognitionListener() {
@Override
public void onReadyForSpeech(Bundle params) {
mButtonSpeech.getBackground().setColorFilter( 0xFFFF0000, PorterDuff.Mode.MULTIPLY );
}
@Override
public void onBeginningOfSpeech() {
mTextView.append( "BEGINNING TO HEAR..." );
mButtonSpeech.getBackground().setColorFilter( 0xFFFFFFFF, PorterDuff.Mode.MULTIPLY );
}
@Override
public void onBufferReceived(byte[] buffer) {}
@Override
public void onEndOfSpeech() {
mTextView.append( "STOP HEARING..." );
mButtonSpeech.getBackground().setColorFilter( 0xFF00FFFF, PorterDuff.Mode.DST );
}
@Override
public void onError(int error) {
String message;
boolean restart = true;
switch (error)
{
case SpeechRecognizer.ERROR_AUDIO:
message = "Audio recording error";
break;
case SpeechRecognizer.ERROR_CLIENT:
message = "Client side error";
restart = false;
break;
case SpeechRecognizer.ERROR_INSUFFICIENT_PERMISSIONS:
message = "Insufficient permissions";
restart = false;
break;
case SpeechRecognizer.ERROR_NETWORK:
message = "Network error";
break;
case SpeechRecognizer.ERROR_NETWORK_TIMEOUT:
message = "Network timeout";
break;
case SpeechRecognizer.ERROR_NO_MATCH:
message = "No match";
break;
case SpeechRecognizer.ERROR_RECOGNIZER_BUSY:
message = "RecognitionService busy";
break;
case SpeechRecognizer.ERROR_SERVER:
message = "error from server";
break;
case SpeechRecognizer.ERROR_SPEECH_TIMEOUT:
message = "No speech input";
break;
default:
message = "Not recognised";
break;
}
mTextView.append("onError code:" + error + " message: " + mes sage);
if (restart) {
getSpeechRecognizer().cancel();
startVoiceRead();
}
}
@Override
public void onEvent(int eventType, Bundle params) {}
@Override
public void onPartialResults(Bundle partialResults) {}
@Override
public void onResults(Bundle results) {
ArrayList<String> text = results.getStringArrayList(SpeechRecognizer.RESULTS_RECOGNITION);
mTextView.append(text.get(0));
mTextView.append( ". " );
startVoiceRead();
}
@Override
public void onRmsChanged(float rmsdB) {}
});
}
return mSpeechRecognizer;
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mButtonSpeech = (ImageButton)findViewById(R.id.button_speech);
mTextView = (TextView)findViewById(R.id.text_slave);
mButtonSpeech.setOnClickListener( new View.OnClickListener() {
@Override
public void onClick(View v) {
if (mSpeechRecognizer == null) {
startVoiceRead();
} else {
stopVoiceRead();
}
}
});
}
public void startVoiceRead() {
Intent speechIntent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
speechIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
getSpeechRecognizer().startListening(speechIntent);
mButtonSpeech.getBackground().setColorFilter( 0xFFFFFF00, PorterDuff.Mode.MULTIPLY );
}
public void stopVoiceRead() {
if (mSpeechRecognizer != null) {
mSpeechRecognizer.destroy();
mSpeechRecognizer = null;
}
mButtonSpeech.getBackground().setColorFilter( 0xFFFFFFFF, PorterDuff.Mode.DST);
}
}
我已经添加权限，以我的Android清单：
I already added permissions to my Android Manifest:
<uses-permission android:name="android.permission.RECORD_AUDIO"/>
<uses-permission android:name="android.permission.INTERNET"/>
问题是，该RecognitionListener功能，如onBeginningOfSpeech（）是随机调用平均每第三次我要激活它扔按钮presses。此外，我没有收到任何效果，但错误code 2：网络错误，如果RecognitionListener被激活。尽管我也跟着教程，我是不是能够发现的差异，使我的code没有工作至今。我的LogCat中输出抛出下面的错误时，pressing按钮：
The problem is, that the RecognitionListener functions like onBeginningOfSpeech() is called randomly in average every third time I want to activate it threw button presses. Furthermore I don't receive any results, but ErrorCode 2: Network Error, if the RecognitionListener is activated. Even though I followed the tutorials, I wasn't able to spot the difference, making my code not work until now. My LogCat output throws the following errors when pressing the button:

不过，即使我想补充

的问题，如上所述，继续
the problems, described above, continue.
感谢您抽出宝贵时间来帮助。这一直是一道坎我一直没能得到还没有结束。
Thanks for taking the time to help. This has been a hurdle I haven't been able to get over yet.
推荐答案
据<一个href=\"http://stackoverflow.com/questions/22916633/use-of-speechrecognizer-produces-error-network-value-2\">Use的SpeechRecognizer产生ERROR_NETWORK（价值2），错误是由三星电子语音API（搭载Vlingo的）引起的。更改语音API在手机设置标准的谷歌API解决的问题。
According to Use of SpeechRecognizer produces ERROR_NETWORK (Value 2), the error was caused by Samsungs speech API (powered by Vlingo). Changing the speech API in the phone settings to standard Google API solved the problems.
