Pronunciation of också
I've never heard anyone pronounce it this way before and I feel pretty sure that it was just because of influence from L1, but I met a Norwegian on a train recently and he spoke pretty good Swedish, however he kept pronouncing också as if it were åsså. I understand that in Norwegian også is pronounced that way, but I just wanted to make sure that I'm not unaware of some regional variant of Swedish in which också is pronounced like it is in Norwegian. I don't think it's too farfetched that it could be, but I wonder how strange it would be to say it in a place like Stockholm.
There's actually a pretty wide range of perfectly fine pronunciations for such a short word. I have absolutely no data to back this up, but I'd wager a small sum on åsså being the most common way. It doesn't really sound out-of-place anywhere in Sweden that I can think of, even where it might not be the default option.
To me, the "åsså" pronunciation would be reserved for "och så" though, while "också" would keep a K-sound in there.
I did a big online survey a few years ago and it was one of the questions. It is certainly a common pronunciation and I hear it often in Skåne.
Most of the responses come from Skåne so there is a small bias, but I took a short look at the answers and most responses were definitely from Skåne and Västergötland.
I had this neighbour from rural Skåne and we’d have these awkward conversations in the hallway where I said: Allt bra? and he said Jadå, du åsså? and that was it.
Where I grew up in Östergötland, everyone would pronounce the k like you said, so it was a bit new to me, but you hear it often in Skåne.
I'd say it's reasonable to assume that också is pronounced like this in many places closer to the Norwegian border. I know it's not unusual to hear icke instead of inte sometimes.
