Very interesting Keth and Óskar, thanks for the effort!

Yes; "og" is often pronounced [O], especially before a consonant.

You can even recognise the dialect. This is the boring Reykjavík
dialect most people speak. Some people (mostly in the southeast)
pronounce "hv" as [w^O] rather than [k^h]. Most poetry presumes
[w^O] pronunciation so it is important to know.

In the north "kápu" would be pronounced [k^hau:p^hY].
There are some very few people left who would pronounced
"veginum" as [vE:jInYm].

You notice that "að" is here pronounced [A].
This is similar to "og" being pronounced [O].

You see (from "ferðamanninn" and "kápunni") that the difference
between one and two n in the article is only in the spelling.
