1.下载科大讯飞语音识别sdk(/sdk/dispatcher)选择语音听写SDK（如下图） ，下载前会让你先创建应用，创建应用后会得到一个appid。然后点“立即开通”去开通“语音识别”功能，之后就会跳出“SDK下载”的页面，然后就可以下载了（未注册账号的要先注册一个账号）。
2.如果是android开发选择android如果是ios选择ios平台(如图)
3.将下载好的sdk中的libs里面的msc.jar以及libmsc.so文件复制到自己创建的libs下面 (如图)
4.接下来将Manifest中添加一下权限并且创建appid时包名需要跟自己创建的工程包名保持一致 (例如 com.vice.android)并且在application中设置android:name以及bunid gradle里面配置sourceSets(如下图)
<!--获取手机录音机使用权限，听写、识别、语义理解需要用到此权限-->
<uses-permission android:name="android.permission.RECORD_AUDIO" />
<!--连接网络权限，用于执行云端语音能力--><uses-permission android:name="android.permission.INTERNET" />
<!--读取网络信息状态--><uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<!--获取当前wifi状态--><uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<!--允许程序改变网络连接状态--><uses-permission android:name="android.permission.CHANGE_NETWORK_STATE" />
<!--读取手机信息权限--><uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /><uses-permission android:name="android.permission.READ_CONTACTS" /><uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /><uses-permission android:name="android.permission.WRITE_SETTINGS" /><uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" /><uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /><uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
5. 具体代码目录结构
6.主要代码如下
