问题描述

更新

我在另一台设备上安装了 iOS 13 GM,没有遇到这个问题。因此,我不再确定这是否特定于 iOS 13 GM,或者与我安装它的方式有关。在第一台设备(iPhone X)上,我进行了升级(通过 iTunes 中的“选项键 + 检查更新按钮”)。在第二台设备(iPhone SE)上,我进行了完全恢复。尚不确定是什么原因导致它进入这种状态。

原始问题

AVSpeechSynthesisVoice.speechVoices()报告说,当我在装有 iOS 13 GM 的设备上运行它时,没有可用的声音。事实上,当我尝试使用它加载语音时,AVSpeechSynthesisVoice(identifier:)它总是返回 nil。它在模拟器中工作。我不认为这是以前的 beta 版本的问题,它似乎在 iOS 13.1 beta 2 和 3 中有效。

有没有人遇到过这种情况,并想出任何解决方法?我没有看到任何有意更改此行为的文档,因此我怀疑这是一个错误。我打算提交雷达。但这对即将发布的 iOS 13 没有帮助。

这种行为在新创建的单视图项目中是可重现的,viewDidLoad在包含的视图控制器中添加了以下琐碎的功能。

override func viewDidLoad() {
    super.viewDidLoad()

    let voices = AVSpeechSynthesisVoice.speechVoices()
    print("Voice Count: \(voices.count)")
}

输出很长:

它重复了最后 7 行 39 次,大概对应于它应该知道的 39 个声音。

解决方案


我遇到了同样的 AVSpeechUtterance 问题,它似乎随着时间的推移在我的设备上自行解决了。在使用之前崩溃的应用程序或全新安装的应用程序一段时间后,我不再在 iOS 13 或 13.1 上崩溃。
