@ScoterD @ai6yr @AlaskaWx @transitionalaspect "x" is the phonetic symbol for the ch sound in Loch Ness, or L'chaim, and that's usually how it's used in transcribing American Indian languages. "š" = sh (Linguists in other countries use a different standardized symbol for this sound; apparently, American linguistics picked up a few bits of Czech spelling from linguists fleeing the Nazi invasion of Czechoslovakia.
"q" is a k sound prounced farther back (or lower) in the throat (which is found in Arabic); if you're trying to incorporate these words into an English sentence you can just say "k". The apostrophe glued on top of another consonant means "glottalization". A glottal stop is the sound you make in the middle of "uh-oh". To make another consonant "glottalized" you either say that at the same time as the base consonant or afterwards.
That's probably more information than you want!
But the "x" and "š" are pretty easy to do.
