How to know gender of system voice

I would need to know which gender is used by the iOS system for speechSynthesis.

I have tried

            let aVoice = AVSpeechSynthesisVoice()
            print(#function, #line, aVoice.gender.rawValue)

But always get 0, for unspecified

I've searched extensively but could not find how to.

So I use a workaround: I test gender for each supported language (out of app) and use this information to adapt to the app selected language.

But not sure that will be robust over time.
