语音合成和识别接口

第一步：导入jar包
再libs文件夹，导入Msc.jar和Sunflower.jar，还有so包（这个要看手机是什么芯片）。

第二步：代码
MainActivity:

package com.example.speechtest2;

import android.view.Menu;
import android.view.MenuItem;
import android.annotation.SuppressLint;

把以下代码放在后面

    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

    <uses-permission android:name="android.permission.WRITE_SETTINGS" />

语音识别返回的是json，如：

{"sn":1,"ls":false,"bg":0,"ed":0,"ws":[{"bg":0,"cw":[{"sc":0.00,"w":"有"}],{"bg":0,"cw":[{"sc":0.00."w":"搞"}],{"bg":0,"cw":[{"sc":0.00,"w":"啊"}]}]}{"sn":2,"ls":true,"bg":0,"ed":0,"ws":[{"bg":0,"cw":[{"sc":0.00,"w":"。"}]}]}
