介紹
? ? ? ?從IOS5開(kāi)始，IOS系統(tǒng)已經(jīng)在siri上集成了語(yǔ)音合成的功能，但是是私有API。但是在IOS7，新增了一個(gè)簡(jiǎn)單的API----AVSpeechSynthesizer來(lái)做這件事情。
案例
? ? ? #import<AVFoundation/AVFoundation.h>
- (IBAction)buttonClick {
AVSpeechSynthesizer * synthsizer = [[AVSpeechSynthesizer alloc] init];
AVSpeechUtterance * utterance = [[AVSpeechUtterance alloc] initWithString:@"aosika先生"];//需要轉(zhuǎn)換的文本
utterance.voice = [AVSpeechSynthesisVoice voiceWithLanguage:@"zh-CN"];//國(guó)家語(yǔ)言
utterance.rate = 0.4f;//聲速
[synthsizer speakUtterance:utterance];
}
語(yǔ)言類(lèi)別
IOS7包含了一組可以用來(lái)合成的聲音的嗓音，你可以自定義多種嗓音來(lái)合成。

總結(jié)
語(yǔ)音合成器非常簡(jiǎn)單，多語(yǔ)言方便使用，可以提高應(yīng)用的訪問(wèn)性。
