I want

GetAttribute(xyz)

to be something like:

GetAttribute("Language")

And then a language is returned as a string maybe, as I want to categorize dozens of voices that the user may have into categories based on their language, I want

GetAttribute("Language")

To return:
"eng-us"
or
"English - United States"
or
"German-Germany"
or
"Arabic-Saudi Arabia"
or
"Spanish-Spain"

So what should I use instead of "Language"?

And what if I want to know if it's a voice of a male or a female?

What I have tried:

SpObjectTokenCategory otc = new SpObjectTokenCategory();

            otc.SetId("HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Speech_OneCore\\Voices");

            ISpeechObjectTokens tokenEnum = otc.EnumerateTokens();

            

            foreach (SpeechLib.ISpeechObjectToken v in tokenEnum)
            {
                string s = v.GetDescription();// thid doesn't always return the language sometimes only the name of the voice
                string a = v.GetAttribute(/*what here?*/);
