我尝试了很多但却找不到，所以我希望你能帮助我。
我正在尝试构建自己的语音识别应用程序，它不显示对话框。
我已经编写了一些代码并且它工作得很好，但我的问题是识别器似乎在LogCat中没有任何错误或其他消息停止。
一个奇怪的事实是，“RecognitionListener”接口中的“onRmsChanged”仍然一直被调用，但不再调用“onBeginningOfSpeech”。
如果我在语音识别开始后发言，那就有效了。 但如果我等了几秒钟就没有了。
使用的API是4.0.3，我使用版本4.2.1将其安装在我的Nexus 7上
如果你有一些好主意，我真的很感激。
一些代码段：
我的课程：
class SpeechListener implements RecognitionListener
{
public void onBeginningOfSpeech()
{
Log.d(TAG, "onBeginningOfSpeech()");
}
public void onBufferReceived(byte[] buffer)
{
Log.d(TAG, "onBufferReceived()");
}
public void onEndOfSpeech()
{
Log.d(TAG, "onEndOfSpeech()");
}
public void onError(int error)
{
Log.d(TAG, "onError(): " + error);
if(error == SpeechRecognizer.ERROR_NO_MATCH)
{
}
else if(error == SpeechRecognizer.ERROR_SPEECH_TIMEOUT)
{
}
else
{
tvOutput.setText("Error: " + error);
}
}
public void onEvent(int eventType, Bundle params)
{
Log.d(TAG, "onEvent()");
}
public void onPartialResults(Bundle partialResults)
{
Log.d(TAG, "onPartialResults()");
}
public void onReadyForSpeech(Bundle params)
{
Log.d(TAG, "onReadyForSpeech()");
}
public void onResults(Bundle results)
{
Log.d(TAG, "onResults(): " + results);
String str = new String();
ArrayList<String> data = results.getStringArrayList(SpeechRecognizer.RESULTS_RECOGNITION);
for(int i = 0; i < data.size(); i++)
{
str += data.get(i) + "\n";
}
tvOutput.setText(tvOutput.getText().toString() + "\n\n" + "Results: " + str);
}
public void onRmsChanged(float rmsdB)
{
Log.d(TAG, "onRmsChanged()");
}
}
我在MainActivity中的实现：
this.srSpeechRecognizer = SpeechRecognizer.createSpeechRecognizer(this);
this.srSpeechRecognizer.setRecognitionListener(new SpeechListener());
this.iSpeechIntent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
this.iSpeechIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
this.iSpeechIntent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE, "voice.recognition.test");
this.iSpeechIntent.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS, 10);
所以它开始了：
srSpeechRecognizer.startListening(iSpeechIntent);

答案 0 :(得分：19)
唯一可以解决此问题的解决方案是使用第三方服务。 4.1.1和4.2 依赖于语音识别服务的一个版本，该服务不遵守记录的行为，因为运行它的服务无声地死亡。
如果您不想使用第三方API，并且您需要以某种方式解释此服务死亡， 可能，但它不是很理想。
服务终止后，将不会调用以下任何方法：
但如果在服务死亡之前调用onBeginningOfSpeech，您可以放心，最终会调用onError或onEndOfSpeech。
因此，如果你想要的是确保你知道Jellybean中服务的生命和死亡，内置SpeechRecognizer中此问题的解决方法是执行以下操作：
为什么这不是维持连续语音识别设置的理想解决方案
在您的问题中没有直接说明，但有些人希望这样做，以便他们可以持续进行语音识别。 这在4.1.1和4.2 中实现这一点并不是一个好方法，因为Google的SpeechRecognition服务现在开始时带有非可选的“bloop”音效。似乎无法关闭此声音。 API中没有列出任何内容来控制它。您的用户不会喜欢在4秒重复循环中“泛滥”。
答案 1 :(得分：3)
您可以尝试提供以下RecognizerIntent个额外内容：
EXTRA_SPEECH_INPUT_COMPLETE_SILENCE_LENGTH_MILLIS EXTRA_SPEECH_INPUT_MINIMUM_LENGTH_MILLIS EXTRA_SPEECH_INPUT_POSSIBLY_COMPLETE_SILENCE_LENGTH_MILLIS 虽然它们都不适合这种情况。 Android根本不提供额外的“WAIT_UNTIL_I_START_SPEAKING”。这不是一个错误（在果冻豆或其他地方），它只是缺乏一个功能。即使在Android的未来版本中添加了这样的额外内容，也可能无法保证语音识别应用程序（例如Google语音搜索）实际上实现了这一点。 RecognizerIntent文档包含大量具有未指定行为的附加内容。
您最好的选择可能是在您onEndOfSpeech或onError后立即重新启动识别器。
答案 2 :(得分：3)
我制作了一个带有音频到语音识别器的服务，每次出现错误或结果时都会通过重新启动来模拟连续性。正如您所看到的，我的服务侦听广播接收器以启动/停止连续ASR（电池价格昂贵，因此我建议您仅在相关UI位于前台时运行此连续ASR服务）。 ASR的结果也会广播到应用程序的其余部分。你可以忽略广播，服务和识别器监听器是主要的想法。 不要忘记INTERNET权限和清单以及服务声明：
<service android:name=".speechRecognitionService" />
SpeechRecognitionService：
/**
* Created by Josh on 22/07/15.
* This service bears an Audio to Speech recognizer (ASR), once this service is started,
* it listens a broadcast called "asrService".
* the Service starts ASR when it receives a "START-ASR" value inside the "message" parameter of its broadcast receiver
* the Service stopss ASR when it receives a "STOP-ASR" value inside the "message" parameter of its broadcast receiver
Example:
Intent intent = new Intent("asrService");
intent.putExtra("message", "STOP-ASR");
LocalBroadcastManager.getInstance(context).sendBroadcast(intent);
Once the ASR Listener that this service bears is running, it will broadcast the results is gets.
To catch ASR results, implement a Broadcast receiver that listens to app.asrResult="ASRresult", for example:
private BroadcastReceiver ASRReceiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
String message = intent.getStringExtra("message");
if(message!=null) {
app.logwhite("ASR says: "+message);
}
}
};
LocalBroadcastManager.getInstance(this).registerReceiver(ASRReceiver, new IntentFilter(app.asrResult));
Unregister the broadcast receiver likewise:
LocalBroadcastManager.getInstance(this).unregisterReceiver(ASRReceiver);

答案 3 :(得分：0)
一段时间以来，我面临着同样的问题，我在任何地方都找不到正确的工作答案。
为了使聆听无限进行，请在重新实例化SpeechRecognizer并重新设置意图对象之后，再次发布onError()或onResults()我是在打电话给speechRecognizer.startListening(intent);。
但是正如您提到的，它最终在听了一段时间后就消失了。
这是我尝试过的方法，对我有用。
我只是确保在回想speechRecognizer.startListening(intent);之前先打电话给
speechRecognizer.stopListening();
speechRecognizer.destroy();
去做第一段中提到的事情。
到目前为止，对我来说一切正常。

我在Node.js库中遇到了同样的问题，这是我与团队的答复一起提交的问题。 https://github.com/googleapis/nodejs-speech/issues/667
TLDR； 设置您的配置如下（注意使用增强型）
const config = {
encoding: "LINEAR16",
sampleRateHertz: 16000,
languageCode: "en-US",
metadata: recognitionMetadata,
model: 'phone_call',
useEnhanced: true}
您将获得以下输出-注意替代方案，在我看来这有点误导性措词，但是哦：
[{"results":[{"alternatives":[{"words":[],"transcript":"I live in Boston","confidence":0.9128385782241821}],"channelTag":0,"languageCode":"en-us"},{"alternatives":[{"words":[],"transcript":" Boston is an amazing City","confidence":0.9128385186195374}],
