Is it possible to use Google TTS with Australian voices?

Hello everyone. I’ve been looking for solutions and answers for the past few months before making a thread and bothering others, but I haven’t found anything that has worked. The default Google TTS American female voice functions perfectly. Changing the accent or dialect of it, particularly the Australian female voice, is where I’m hitting a wall. The Australian voice, even though I am probably spending far too much time trying to make it work, simply sounds better to me. Prior to switching to this amazing project, I always used this voice for my Google Assistant.

I’ve read posts from years ago with solutions (listed below), but, they don’t seem to work for me.

, the codes I’ve tried are:

{
   "max_allowed_core_version":21.2,
   "tts":{
      "module":"google",
      "google":{
         "lang":"en-au"
      },
      "lang":"en-us"
   }
}

Also tried

{
   "tts":{
      "google":{
         "lang":"en-au"
      }
   }
}

To no avail, the voice continues to be the typical American female Google voice. I’m not sure if I’m just doing it incorrectly or if Google TTS cannot be used on Mycroft to accomplish this. I would be grateful for any assistance.
