學會使用 AVSpeechSynthesizer 講話

簡單製作一個注音符號發音器，讓大家重回小時候學國語的時光

執行步驟

1. 在畫面上準備每個注音符號，並於每個注音上設置一個按鍵，以IBAction到 speak 上

2. 新增可調整速度/音量的滑桿，並拉出 IBOutlet

@IBOutlet weak var rateSlider: UISlider!
@IBOutlet weak var volumeSlider: UISlider!

3. 將每個注音的按鍵其IBAction都指定到 speak 函式，在此利用按鍵上面的tag屬性分辨其所對應的注音符號

@IBAction func speak1(_ sender: UIButton) {
    let data = ary[sender.tag]
    
    print(data, rateSlider.value, volumeSlider.value)
    
    let speech = AVSpeechUtterance(string: data)
    speech.voice = AVSpeechSynthesisVoice(language: "zh-TW")
    speech.rate = rateSlider.value
    speech.volume = volumeSlider.value
    let synthesizer = AVSpeechSynthesizer()
    synthesizer.speak(speech)
}
