I have a confusion with the pronunciation. The audio sounds like "chuaa". Is this correct. I also observed "k" being pronounced as "ch" in kylling.
This is a different 'k' than in 'kylling', which indeed sounds like 'ch' or 'sh'. Here the 'k' sounds very much like the 'ck' in 'cuckoo'. I think the pronounciation of 'kua' is very close to 'ckoo' (as in 'cuckoo') + 'ah' (with a silent 'h'). I can't think of any english words which would start with a similar sound to 'kua', hence the complicated example above. Hope this helps.
