AVSpeechSynthesizer语言

Question

在我的应用程序中，我使用的是AVSpeechSynthesizer，文本语音是俄语，问题是当我将系统语言更改为英语时，文本发音带有英语口音，听起来像俄语的转录。我该如何处理这个问题？

下面是一些代码

    utterance.voice = AVSpeechSynthesisVoice(language: "ru-Ru")
    synthesizer.pauseSpeaking(at: .word)
    utterance = AVSpeechUtterance(string: "Какой-то текст который нужно произнести")
    synthesizer.speak(utterance)

Answer 1

也许它会对某些人有帮助，我找到了解决方案，但它看起来像是在说话之前我改变了AppLanguage的变通办法，这是代码

    UserDefaults.standard.set(["ru"], forKey: "AppleLanguages")
    UserDefaults.standard.synchronize()
    utterance.voice = AVSpeechSynthesisVoice(identifier: "ru-RU")

同步之后，AVSpeechSynthesisVoice.currentLanguageCode()变成了"ru“，忽略了系统语言

以下是土耳其语的完整代码示例

导入UIKit

导入AVFoundation

类ViewController: UIViewController {

let synthesizer : AVSpeechSynthesizer = AVSpeechSynthesizer()
var utterance : AVSpeechUtterance = AVSpeechUtterance(string: "")

override func viewDidLoad() {
    super.viewDidLoad()
    UserDefaults.standard.set(["tr"], forKey: "AppleLanguages")
    UserDefaults.standard.synchronize()
}

override func viewDidAppear(_ animated: Bool) {
    super.viewDidAppear(animated)
    try? AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback, with: .interruptSpokenAudioAndMixWithOthers)
    utterance.voice = AVSpeechSynthesisVoice(identifier: "tr-TR")
    synthesizer.pauseSpeaking(at: .word)
    testSpeech()
}

private func testSpeech() {
    utterance = AVSpeechUtterance(string: "Çeviri için deney metni")
    speak()
}

private func speak() {
    if synthesizer.isSpeaking {
        synthesizer.pauseSpeaking(at: .immediate)
        return
    }
    synthesizer.speak(utterance)
}

}
