A family of Microsoft word processing software products for creating web, email, and print documents.
Change your Proofing language from English (US) to English (Canada) restart word and try again it should sound different. Sadly you cant use Aria or Jenny natural voices that way in word.
I was able to do this with my Windows 11 laptop a couple days ago, but the iOS mobile app only has the US english voices in the voice pack. But thank you for the reply!
