toggleButton.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
@Override
public void onCheckedChanged(CompoundButton buttonView,
boolean isChecked) {
initSpeech();
if (isChecked) {
progressBar.setVisibility(View.VISIBLE);
progressBar.setIndeterminate(true);
speech.startListening(recognizerIntent);
} else {
progressBar.setIndeterminate(false);
progressBar.setVisibility(View.INVISIBLE);
speech.stopListening();
}
}
});
在onCheckedChange（）中调用initSpeech。否则有时可能会销毁speechReconginzer对象。
这可能对您有所帮助
如果发生Reconginzer忙错误，请尝试销毁语句对象onError（）endOfSpeech（）和onResults（）
