Swift playgrounds ios 10个文字转语音命令代码

Question

我在 iOS iPad 上使用 swift 游乐场来创建文本转语音命令。下面是代码。

import AVFoundation
let synthesizer = AVSpeechSynthesizer()
let utterance = AVSpeechUtterance (string: "Say     
Hello")
utterance.rate = 1
synthesizer.speak(utterance:   
AVSpeechUtterance)

//当我点击"run my code"。我收到错误消息 "Attempt to evaluate editor placeholder" 我不知道这个错误是什么意思。希望有人能提供帮助。谢谢你。

Answer 1

utterance: AVSpeechUtterance 只是一个编辑器占位符，告诉您应该放在那里的内容：

synthesizer.speak(utterance: AVSpeechUtterance)

您需要调用它并传递您创建的话语对象：

synthesizer.speak(utterance)

要让它说话，您还需要几行。这是完整的代码：

import AVFoundation
import PlaygroundSupport

PlaygroundPage.current.needsIndefiniteExecution = true

let synthesizer = AVSpeechSynthesizer()
let utterance = AVSpeechUtterance(string: "Say Hello")

utterance.rate = 0.5

synthesizer.speak(utterance)
