ios 15.0.2 how to change siri voice

Anyone else having problems with Siri Voice keep changing back to American? For years I've been using the Australian female accent but every few days, after changing back, it changes back to American when using CarPlay.

I have automations in shortcuts where I have them speak when I need to be hands free, the voices are now the stock voice and can't change them at all in addition to the Siri issue. I prefer the Australian Siri too, just sounds so much better.

I was on with support yesterday and they could not find any problems with my phone. They finally asked me to backup, wipe the phone and restore and try again. Really don’t want to go that dramatic yet. Is yours with car play ?
