Is the щ in що always pronounced "shch"? When I visited Ukraine (many years ago) I thought people I heard said it like a single soft "sh" sound, without the "ch", like the Polish or Russian soft sh sounds.
The correct pronunciation is "shch," but in some dialects it is pronounced as "sh" in some words. The most common is "шо" instead of "що." Many people pronounce it like this in the colloquial speech.
I think the audio for this sentence is the perfect example of the correct pronunciation.
