It seems to me that the letter L mid-word often sounds more like an R, specifically the tapped (alveolar) R. For example, in "Kan jeg få betale", the word "betale" sounds more like "betare" to me. It happens with a lot of words, at least in some peoples' pronunciation of it. I think there are also people who don't pronounce it like this. Is this a regional/dialectical difference? I know there is no official standard of Norwegian, but do you have a recommendation about whether to use it?
