Two classes are used

AVSpeechSynthesizerAVSpeechUtterance

AVSpeechSynthesizer *av= [[AVSpeechSynthesizer alloc]init];av.delegate=self;//挂上代理AVSpeechUtterance *utterance = [[AVSpeechUtterance alloc]initWithString:@"你好！"];//需要转换的文字 utterance.rate=0.5;// 设置语速，范围0-1，注意0最慢，1最快；AVSpeechUtteranceMinimumSpeechRate最慢，AVSpeechUtteranceMaximumSpeechRate最快 AVSpeechSynthesisVoice*voice = [AVSpeechSynthesisVoice voiceWithLanguage:@"zh-TW"];//设置发音，这是中文普通话 utterance.voice= voice;[av speakUtterance:utterance];//开始

Avspeechsynthesizer defines a number of callback proxies that can detect some states

-(void) SpeechSynthesizer:(avspeechsynthesizer*) Synthesizer didstartspeechutterance:(avspeechutterance*) utterance{NSLog(@"---start playing");} -(void) SpeechSynthesizer:(avspeechsynthesizer*) Synthesizer didfinishspeechutterance:(avspeechutterance*) utterance{NSLog(@"---complete playback");} -(void) SpeechSynthesizer:(avspeechsynthesizer*) Synthesizer didpausespeechutterance:(avspeechutterance*) utterance{NSLog(@"---play Abort");} - (void) SpeechSynthesizer:(avspeechsynthesizer*) synthesizer didcontinuespeechutterance:(  avspeechutterance*) utterance{NSLog(@"---resume Playback");} - (void) SpeechSynthesizer:(avspeechsynthesizer*) synthesizer didcancelspeechutterance:(  avspeechutterance*) utterance{NSLog(@"---play Cancel");}
