首先仙畦，文字轉(zhuǎn)語音最簡單的方案就是使用系統(tǒng)提供的接口

一、AVSpeechSynthesizer

AVSpeechSynthesizer開放的接口數(shù)量少廉邑，很難滿足我們開發(fā)的各種需求哥蔚，這個時候第三方的語音就是我們比較好的選擇。蛛蒙。

文本轉(zhuǎn)語音技術(shù), 也叫TTS, 是Text To Speech的縮寫. iOS如果想做有聲書等功能的時候, 會用到這門技術(shù).
iOS7之后才有該功能
需要 AVFoundation 庫
AVSpeechSynthesizer: 語音合成器, 可以假想成一個可以說話的人, 是最主要的接口
AVSpeechSynthesisVoice: 可以假想成人的聲音
AVSpeechUtterance: 可以假想成要說的一段話

二糙箍、百度語音包

百度語音，我選擇的是百度語音包ＧＫ睢（盡管百度一直狠招黑）
2.1下載離線合成語音包
