ios 将文本转化成语音

啥都不说：

直接上代码

   AVSpeechUtterance *utterance = [AVSpeechUtterance speechUtteranceWithString:@"你好我使用台语发音跟你说话。"];
    //台语发音
    AVSpeechSynthesisVoice *voice = [AVSpeechSynthesisVoice voiceWithLanguage:@"zh-TW"];
    utterance.voice = voice;
    utterance.volume = 1.0;
    utterance.rate= 0.2;  //设置语速
    utterance.pitchMultiplier= 1.1;
    NSLog(@"%@",[AVSpeechSynthesisVoice speechVoices]);
    AVSpeechSynthesizer *synth = [[AVSpeechSynthesizer alloc]init];
    [synth speakUtterance:utterance];
