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();
        }
    }
});

在onCheckedChange（）中调用initSpeech。否则有时可能会销毁speechReconginzer对象。

这可能对你有所帮助

如果发生Reconginzer忙错误，尝试销毁语句对象onError（）endOfSpeech（）和onResults（）
