目前语音功能比较出名的就是百度、讯飞语音，当然还有其他平台的语音功能，比如微信之类的。
目前我只用过百度、讯飞的语音，具体是讯飞的语音识别和百度的语音合成。很奇葩是吧，为啥要分开来用。要么就选讯飞的语音识别+语音合成，要么就选讯飞的语音识别+语音合成。老板要求的，这个理由够不够，哈哈哈~
回归正题，百度的语音合成，建个新工程再玩一下。
一、百度语音开放平台注册应用
百度语音开放平台：
百度语音-永久免费智能语音开放平台
二、Xcode导入相应的库
你点击你创建的应用，里面有对应的SDK供你选择。当处创建应用的时候，由于你只选了语音合成，所以只能下载语音合成的SDK。TTS就是语音合成。
导入必备的的库，并且把TTS对应的文件也拖进来。
三、开始使用TTS
