Are the l and the t pronounced in zvlástní? (My keyboard does not have the caron sign).
BTW, the 'caron' sign is in Czech called 'a hook' - háček.
If you have a czech keyboard, š should be under 3
From what I understand, EVERY letter in Czech is pronounced. Also, I think if there are two of the same letter in a row, EACH is pronounced separately, rather than both being sort of run together as in English.
