iOS7发布时增加了Text To Speech API，这里是它支持的语言，做个备忘，方便以后查。

iOS7将其封装在AVSpeechSynthesis一系列文件里，可以使用AVSpeechSynthesisVoice来查看它所支持的语言：

#import <AVFoundation/AVFoundation.h>
#import <AVFoundation/AVSpeechSynthesis.h>

// ...
NSArray* voices = [AVSpeechSynthesisVoice speechVoices];
for (AVSpeechSynthesisVoice* voice in voices) {
    NSLog(@"%@", voice);
}

运行结果：

  • Language: th-TH
  • Language: pt-BR
  • Language: sk-SK
  • Language: fr-CA
  • Language: ro-RO
  • Language: no-NO
  • Language: fi-FI

支持的语言还是挺多的。默认语音听起来质量并不差，说明它的语音文件应该不算小，假设一个语音文件要200m，那么只存语音文件就需要7个G，而它的系统文件也才几个G，能存储这36种语言的语音文件，实在有够NB。
