Android科⼤讯飞在线和离线语⾳听写效果图：
参考资料
项⽬⾥要⽤语⾳听写，想到了科⼤讯飞，参考上⾯的资料完成了最简单的在线有UI的语⾳识别，后⾯想要改成离线也可以使⽤。参考下⾯的⽂章
下载好语记和离线资源之后，想要改成有UI的RecognizerDialog离线语⾳听写，但是没成功，试了⼀下没有UI的SpeechRecognizer，发现可以，只需在设置参数的时候加上⼀句
recognizer.setParameter(SpeechConstant.ENGINE_TYPE,SpeechConstant.TYPE_LOCAL);//调⽤语记接⼝
就可以使⽤了。可能是RecognizerDialog带有UI界⾯，已经默认写成在线的了吧
下⾯只贴出主活动的代码，其他参考上⾯的资料

离线语⾳做了个简单的UI，效果如图：
完整代码如下，改动部分已注释：
error parse ample.administrator.voicerecognition;
import android.app.ProgressDialog;
