Answer 1

This works for me

NSLocale *currentLocale = [[NSLocale alloc] initWithLocaleIdentifier:[NSLocale currentLocale].localeIdentifier];

 for (AVSpeechSynthesisVoice *voice in [AVSpeechSynthesisVoice speechVoices]) {
            NSString *languageLocalised = [currentLocale displayNameForKey:NSLocaleIdentifier value:voice.language];
            NSLog(@"%@ displayNameForKey %@: %@", currentLocale.localeIdentifier, voice.language, languageLocalised);
 }
