180.n1-科大讯飞语音识别

可以参考科大讯飞官网的文件MSC Develop Manual for Android.pdf，参考其文件中的代码：

第一步：打入sdk，将开发包libs下面的文件夹拷贝到工程的lib下面的目录中

第二布：添加权限

<!-- 连接网络权限，用于执行云端语音能力 -->    <uses-permission android:name="android.permission.INTERNET" />    <!-- 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" />    <!-- 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" />    <!-- 读取联系人权限，上传联系人需要用到此权限 -->    <uses-permission android:name="android.permission.READ_CONTACTS" />

第三步：初始化，初始化即 创建 语音配置对象 语音配置对象 ，只有初始化 ，只有初始化 ，只有初始化 后才可以使用 后才可以使用 后才可以使用MSC的各项服务建议 将初始化放在 将初始化放在 在 程序入口处比如（Application,Activity的onCreate方法中），初始代码参考如下：

// 初始化语音引擎，将12345678换成您申请的appid，申请地址http://open.voicecloud.cn/SpeechUtility.createUtility(this, SpeechConstant.APPID + "=12345678");

添加几个布局按键

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent" >    <Button        android:id="@+id/button1"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_alignParentTop="true"        android:layout_centerHorizontal="true"        android:layout_marginTop="81dp"        android:onClick="listen"        android:text="开始听写" />    <Button        android:id="@+id/button2"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_below="@+id/button1"        android:layout_centerHorizontal="true"        android:layout_marginTop="40dp"        android:onClick="listenUI"        android:text="交互动画" />    <Button        android:id="@+id/button3"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_below="@+id/button2"        android:layout_centerHorizontal="true"        android:layout_marginTop="33dp"        android:onClick="read"        android:text="语音朗诵" /></RelativeLayout>
