Who cares if the pronunciation is not 100% perfect? Maybe this is a way to tell the general public, that this is not an English speaking carrier and who cares as long as one understands what they are talking about?
Yes I know that our friend mandraskim, bless her heart, had difficulties understanding the gibberish that came out of the speakers (we never found out if it was English or Finnish or just sounds and I still don't know what the H happened over in that thread) but then again who cares? My partner is Finnish and she speaks English with a broad Finnish accent and tbh I would not have it any other way...
I think it's good that they have a Finnish native speaker to speak English through the pre-recorded announcements and same for the Swedish version.
I think it's charming...
