text-to-speech - 更新后某些用户的 iOS 13 文本转语音 (TTS - AVSpeechSynthesisVoice) 崩溃

Question

我们看到一小部分用户在更新到 iOS 13 后出现与 TTS 问题相关的奇怪崩溃。有人知道为什么会发生这种情况吗？有人遇到过同样的崩溃吗？

let voices = AVSpeechSynthesisVoice.speechVoices()

for voice in voices {
  if voice.name == storedName {
     synthVoice = voice
     break
  }
}

...

let utterance  = AVSpeechUtterance(string: text)
utterance.voice = self.synthVoice
self.synthesizer.speak(utterance)

崩溃日志:

Answer 1

更新:问题似乎已在 iOS 13.2 中修复!耶!

在某些运行 IOS 13 的设备上看起来像是一个错误(在我的例子中是 iPhone SE 上的 13.1.2)，

AVSpeechSynthesisVoice.speechVoices()

返回零。

此外，仅供引用，使用 AVSpeechSynthesisVoice 初始化程序设置语音，例如

AVSpeechSynthesisVoice(language: "fr-FR")

导致语音被设置为零，英语被用作后备/默认。

我已经就这两个问题提交了反馈...并且之前 this one 在 13 beta 期间修复了，但现在我不太确定...因为这个新问题要么取代它，要么是不同部门的工程师在交叉目的上工作的结果。
