Meghan Markle learning to be royal. Read description

I read online that Meghan is receiving lots of training in "how to be royal" before her wedding to Prince Harry. One of the areas is elocution lessons to tone down her American accent and change her vocabulary to English words so she is not saying things like trash or pants etc.

It's not that controversial, I just thought I'd see how people feel about it.

Do you think this is old fashioned and she should be accepted for the American she is? Or is it what she signed up for in becoming a royal? Is she disowning her own culture?
