ios - AVSpeechSynthesisVoice 未正确加载

我想在 iOS 上玩文字转语音，但我立即遇到了障碍。声音不想改变为不同的语言或口音。仅供引用，我正在运行 iOS 9 beta 3，可能只是一个错误，但这是我的代码:

    let utter = AVSpeechUtterance(string: "hello and good morning")
    let voice = AVSpeechSynthesisVoice(language: "en-au")
    utter.voice = voice

    if voice == nil {
        print("bad voice")
    }

    let synth = AVSpeechSynthesizer()
    synth.speakUtterance(utter)

它确实在控制台中给了我这个错误:

AXAlternativeVoices was unable to retrieve custom voice assets. This could possibly be caused by someone requesting voices they are not entitled to. Error: Error Domain=ASError Code=15 "The operation couldn’t be completed. (ASError error 15 - Unable to copy asset information)" UserInfo=0x13e662970 {NSDescription=Unable to copy asset information}

有没有其他人遇到过这个问题，我在网上找不到任何东西。谢谢。

代替"en-au"，试着说"en-AU"。
