AVSpeechSynthesizer * synthsizer = [[AVSpeechSynthesizer alloc] init];

AVSpeechUtterance * utterance = [[AVSpeechUtterance alloc] initWithString:@"aosika先生"];//需要轉換的文本

//設置語言類別（不能被識別，返回值為nil）@"zh-CN"國語@"zh-HK"粵語@"zh-TW"臺灣

//self.voiceType = [AVSpeechSynthesisVoice voiceWithLanguage:@"zh-CN"];

//self.utterance.voice = self.voiceType;

utterance.voice = [AVSpeechSynthesisVoice voiceWithLanguage:@"zh-CN"];//國家語言

//設置語速快慢?

utterance.rate = 0.4f;//聲速

[synthsizer speakUtterance:utterance];
