Answer 1

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(); 
     } 
    } 
}); 

的onCheckedChange（）的内部呼叫initSpeech否则有时所述speechReconginzer对象可能被破坏。

这可能会帮助你

试图摧毁讲话对象的onError（）endOfSpeech（）和onResults（）如果Reconginzer忙中出错发生
