标签: swift text-to-speech

我正在尝试将文本到语音的语言代码(在BCP 47中)转换为描述性字符串,以选择在应用程序中具有文本到语音功能的语言。

预期-

阿拉伯语(沙特阿拉伯)-ar-SA 中文(中国)-zh-CN 中文(中国香港特别行政区)-zh-HK 中文(台湾)-zh-TW 捷克文(捷克共和国)-cs-CZ

实际-

ar-SA(固定) cs-CZ(固定)

class func getListOfSupportedLanguages() {
        for voice in (AVSpeechSynthesisVoice.speechVoices()){
            print(voice.language)
            let language = Locale.init(identifier: voice.language)
            print(language.description)
        }
    }

我正在关注这个有用的网站,并获得了不同的结果。

@property (strong, nonatomic) NSArray *languageCodes;
@property (strong, nonatomic) NSDictionary *languageDictionary;
@property (strong, nonatomic) AVSpeechSynthesizer *synthesizer;

- (NSArray *)languageCodes
{
    if (!_languageCodes)
    {
        _languageCodes = [self.languageDictionary keysSortedByValueUsingSelector:@selector(localizedCaseInsensitiveCompare:)];
    }
    return _languageCodes;
}

// Map between language codes and locale specific display name
- (NSDictionary *)languageDictionary
{
    if (!_languageDictionary)
    {
        NSArray *voices = [AVSpeechSynthesisVoice speechVoices];
        NSArray *languages = [voices valueForKey:@"language"];

        NSLocale *currentLocale = [NSLocale autoupdatingCurrentLocale];
        NSMutableDictionary *dictionary = [NSMutableDictionary dictionary];
        for (NSString *code in languages)
        {
            dictionary[code] = [currentLocale displayNameForKey:NSLocaleIdentifier value:code];
        }
        _languageDictionary = dictionary;
    }
    return _languageDictionary;
}

多亏了Matt,我可以正常使用-NSLocale具有displayName,而Locale没有。根据下面的帖子

NSLocale Swift 3

这是代码-

   class func getListOfSupportedLanguages() {
         let current = Locale.current.languageCode

         for voice in (AVSpeechSynthesisVoice.speechVoices()){
              let language = NSLocale.init(localeIdentifier: current!)
              print(language.displayName(forKey: NSLocale.Key.identifier, value: voice.language)?.description as! String)
         }
   }

输出-

English (Australia)
English (United Kingdom)
English (Ireland)
English (United States)
English (South Africa)
