播放语音

1 2 3 4 5 6 7 8 9

let player = AVSpeechSynthesizer(); player.delegate = self; let u = AVSpeechUtterance(string: "今天天气不错"); u.voice = AVSpeechSynthesisVoice(language: "zh-CN"); u.volume = 1.0;//音量 [0-1] Default = 1 u.rate = 0.48;//播放速度 u.pitchMultiplier = 1.0;//播放基准音调 [0.5 - 2] Default = 1 player.speakUtterance(u);

在iPhone6以下rate设置为0.1否则会读的很快 iOS的坑啊
