我尝试了很多但找不到它，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，但它不会显示对话框。
我已经写了一些代码，它工作得很好，但我的问题是识别器似乎停止了，LogCat 中没有任何错误或其他消息。
一个奇怪的事实是，“RecognitionListener”接口(interface)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说话，它会起作用。 但如果我等几秒钟就不会了。
使用的 API 是 4.0.3，我将它安装在 Nexus 7 上，版本为 4.2.1
如果您有一些好主意，我将不胜感激。
一些代码 fragment :
我的类(class):
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);
就这样开始了:
srSpeechRecognizer.startListening(iSpeechIntent);

最佳答案
可以肯定解决此问题的唯一解决方案是使用第 3 方服务。 4.1.1 和 4.2 都依赖于不遵守记录行为的语音识别服务版本，因为运行它的服务会默默地死掉。
如果您不希望使用 3rd 方 API，并且您需要以某种方式解决此服务死亡问题，则 是 可能的，但它并不漂亮或不理想。
一旦服务终止，以下方法将永远不会被调用:
但是如果在服务终止之前调用 onBeginningOfSpeech，您可以确定最终会调用 onError 或 onEndOfSpeech。
因此，如果您只想确保了解 Jellybean 中服务的生死，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
您的问题中没有直接说明，但有些人希望这样做，以便他们可以进行连续的语音识别。 这在 4.1.1 和 4.2 中并不是一个真正的好方法，因为 Google 的 SpeechRecognition 服务现在以非可选的“bloop”声音效果开始。似乎没有办法关闭此声音。 API 中没有列出任何东西来控制它。您的用户不会喜欢在 4 秒的重复循环中被“吹嘘”。
