According to this post it should be pronounced [so‿uk] or [soʲuk] (not sure which one would be correct, but I'd guess the first one). The "ǧ" is more or less silent, but I wonder why there isn't a "k" sound here. I do hear the "soǧu" part, though (at least I think that that is what I hear), which wouldn't be too different from the American pronunciation of English "so" ([soʊ]).
This has to do with context and what sounds ok in English. It takes a very specific context to say "a man is very cold." You have to have a group of context salient men, out of which only one of them is cold. It could be better to say "bir adam" in this case. :)
