The "Č" is like "Cz" in "Czech". "á" is a long vowel, not a stress. The "ř", is some sort of mix between a rolled "r" and a "z", but I think it's basically unpronounceable for non-Czechs...
Czech is like Finnish with the stress always on the first syllable. You can't be me, I'm taken
Though most visitors are confused by the fact that every letter is pronounced: if there is a double t you can hear the difference with a single t etc. You can't be me, I'm taken
