iOS: 讯飞语音的使用
一、介绍：
讯飞语音做的相当不错，容错率达到90%多，如果需要做语音方面的功能，它绝对是一个不错的选择。讯飞语音的功能很多：语音听写、语音识别、语音合成等，但我们最常用的还是语音听写。讯飞语音中包含界面的语音听写和不带界面的语音听写，下面我来演示一下。
二、准备工作：
(1)去讯飞语音开发平台注册账号并登陆，然后在控制台创建应用，获取对应的app id，这个以后使用它注册激活讯飞语音。
(2)下载讯飞语音SDK，将其拖入到项目中，然后添加需要所有的依赖库，另外还有新添加库Contacts.framework,编译运行即可。
(3)引入头文件，以及遵从代理,激活讯飞语音，并实现功能。
三、BitCode 设置
在 Xcode 7 默认开启了 Bitcode,Bitcode 需要工程依赖的类库同时支持。而语记 SDK 暂时还不支持Bitcode,所以可以先临时关闭。后续支持 Bitcode 请关注讯飞开放平台版本更新,QQ 群中也会醒。在 Targets - Build Settings 中搜索 Bitcode 即可,找 到相应选项,设置为 NO。
四、演示：
第一种不带界面的语音听写：
DDHomeSearchViewController.m
