AVSpeechUtterance - Swift - 用短语初始化 [英] AVSpeechUtterance - Swift - initializing with a phrase

问题描述

所以我只是想在Swift中使用AVSpeechSynthesizer。我无法弄清楚如何为AVSpeechUtterance设置短语。

So I'm just trying to use the AVSpeechSynthesizer with Swift. I cannot figure out how to set the phrase for the AVSpeechUtterance.

@IBAction func buttonSpeakClicked(sender:UIButton)
    {
        var mySpeechSynthesizer:AVSpeechSynthesizer = AVSpeechSynthesizer()
        var myString:String = "This is the phrase to say"
        var mySpeechUtterance:AVSpeechUtterance = AVSpeechUtterance(string:myString)

        println("\(mySpeechUtterance.speechString)")
        println("My string - \(myString)")

        mySpeechSynthesizer .speakUtterance(mySpeechUtterance)
    }

First println - Nil

First println - Nil

Second println - 这是要说的短语

Second println - This is the phrase to say

文档说init（字符串字符串：字符串！），但我无法弄清楚把它放在哪里

Documentation says init(string string: String!), but I can't figure out where to put it

推荐答案

代码很好，语音字符串设置正确。但问题是AVSpeechUtterance在iOS 8 Beta上没有按预期工作。我建议在这里提交错误报告。

The code is fine, speech string is set correctly. However issue is that AVSpeechUtterance is not working as expected on iOS 8 Beta. I suggest file a bug report here.

代码在iOS 7.1设备和模拟器上正常工作。

The code works fine on iOS 7.1 device and simulator.
