- 第一步：引入头文件
#import <AVFoundation/AVSpeechSynthesis.h>- 1
- 第二步：创建speechSynthesizer合成器实例
AVSpeechSynthesizer *speechSynthesizer = [[AVSpeechSynthesizer alloc]init];- 1
- 第三步：根据你要转换的文本，创建一个属于你的专属“代言人”
AVSpeechUtterance *utteranceNuoYi = [[AVSpeechUtterance alloc]initWithString:@"Attraper des étoiles "]; AVSpeechUtterance *utteranceLiuYe = [[AVSpeechUtterance alloc]initWithString:@"Noé, chéri "];- 1

- 第四步：根据你对代言人的要求，可以更改代言人的voice、pitch、rate
utteranceNuoYi.voice = [AVSpeechSynthesisVoice voiceWithLanguage:@"fr-CA"]; utteranceLiuYe.voice = [AVSpeechSynthesisVoice voiceWithLanguage:@"fr-CA"]; //音高pitch // [0.5 - 2] Default = 1,就是声音的粗细问题。 utteranceNuoYi.pitchMultiplier = 0.7; //说话的快慢 //Values are pinned between AVSpeechUtteranceMinimumSpeechRate and AVSpeechUtteranceMaximumSpeechRate. utteranceNuoYi.rate = AVSpeechUtteranceMinimumSpeechRate; //调整音量的高低。 // [0-1] Default = 1 utteranceNuoYi.volume = 0.8;- 1

- 第五步：把你的代言人 添加到你的整个流程上，之后就可以发言了。
- 根据API：If the synthesizer is speaking, utterances are added to a queue and spoken in the order they are received.说明你的代言人是可以有多个，并且你是以一种队列(FIFO)的方式管理他们的。
[speechSynthesizer speakUtterance:utteranceNuoYi]; [speechSynthesizer speakUtterance:utteranceLiuYe];- 1

以上就已经实现了文本转语音的功能。
