I'd be curious to know whether a "generic" Norwegian speech recognition would work in that scenario. Windows SP 11 does have a Norwegian engine, but I don't know how well it handles different dialects.
In English there are different engines to try to better serve different English dialects, but a lot of other cultures still are stuck with one engine no matter what version of a language you speak.
Actually, I have a question for our German folks: Does the German engine struggle with some German dialects? I don't expect it to understand Swiss or anything extreme like that, but have you noticed whether it works better for certain German dialects than for others?
Post Script: If anyone is interested, users have recorded VC demos in a variety of languages (Dutch, German, Portuguese, Russian), while others are able to use VC in English despite having very strong accents.
