我已经对google离线语音识别进行了研究.但它在Google nexus 5(操作系统：-4.4)中工作正常,但是如果在三星Galaxy S5(OS：-5.0)中实现,则它不会识别并显示此错误：
8- ERROR_RECOGNIZER_BUSY.
以下是我的代码通过将此链接作为参考,我已经做出了http://www.truiton.com/2014/06/android-speech-recognition-without-dialog-custom-activity/的修改
没有互联网的声音必须承认.我已经在口袋狮身人面像上工作,但是它需要很多方面的声音,所以客户端已经拒绝了.

解决方法
当您没有密切关闭SpeechRecognizer时,通常会抛出ERROR_RECOGNIZER_BUSY.哟可能已经在使用SpeechRecognizer的一个实例了.
见这http://developer.android.com/reference/android/speech/SpeechRecognizer.html
