This is just an observation, everyone feel to disagree. As a north american, I notice we have more boisterous voices in regular speech vs. Most Europeans and Brits. I had heard the accounting for that to be down to space.
Here we live with a general expanse of space. American style kind of leans to houses with bigger footprints. Lots of landscape and wilderness. Whereas in Europe cities have more density. Like Ina restaurant in Europe, tables are close together so the polite thing is to have a gentler voice and not have a full boisterous voice. In the US and Canada the restaurant tables are far and often have barriers for privacy. Going from the NA models to Europe .. I think it can lead to the loud American (Canadian) trope at restaurants. It's just a matter of not adjusting to the difference.
But I wonder if a similar effect plays out in normal speaking voices. The expectation is set by the environment we grow up in? I love a soft soothing voice....
Interesting take on it, you are maybe loud but you also pause a lot, as to have time to think and you do think a lot, most of the time how to avoid hurting someone's feelings, here we are not that advanced (not yet so many ppl in therapy)
also, the attitude is to be cheerful as much as possible, here in Europe we just don't do it, the values are about being humble, not to brag... you guys re the perfect opposites, it is expected that you brag and if you don't something is off with you
so I guess being soft-spoken might be part of being polite
what throws me off is that manbun Anne Marie looks very much macho like, very manly, he works in that way and then he opens his mouth and I am in awe, and suddenly I hear old nice lady speaking
Oops, I wanted to post a smiley... nice theory, but it doesn't really work, try going to Italy! And: the "neutral" British accent is often called "RP", Received Pronunciation.
but in the pub or even parliament in UK with all the old Etonians it sounds like a cowbarn
