I couldn't even tell if it was Swedish or English! I'm sure I'll figure it out with practice...
I studied English phonetics for a while so I'm going to try to tell you the difference between these to a's, I hope I can make this clear haha.
The a in the English word 'man' is sort of followed by an e (like in dress) so you actually kind of say maen, but sort of quikly so it's very subtle (the phonetic symbol for this a is actually æ). The a in the Swedish word 'man' is more 'just an a' like when the doctor says "say aaah" but then a little more flat.
I myself get confused by reading this but I hope you get something out of it!
Haha I was actually just joking, since they're so similar ;) My accent means that I pronounce it the same as Swedish anyway. But thank you even still! ^^
