我尝试在我的应用程序 TTS 中集成，但如果单击按钮，则没有音频输出。这是按钮代码：

struct VocabDetailView: View {
//...
    var body: some View {
//...
        HStack{
            Button("Play") {
                readOut(text: "test")
            }
        }
    }
}
//The code from readOut is:

func readOut(text: String) {
    let utterance = AVSpeechUtterance(string: text)
    utterance.voice = AVSpeechSynthesisVoice(language: "en-US")

    let synth = AVSpeechSynthesizer()
    synth.speak(utterance)
}

每次我单击按钮时，Xcode 的输出字段中都会显示：
