I incorrectly typed ''You speak and listen'' and it was accepted? but Duolingo pointed out that ''you missed a space'' ?. ''I'' should have been in there, which completely changes the meaning of the sentence
Must have been a Duo glitch, or a peculiar way of giving you a (supposedly) "correct" answer, because "You speak and listen" is not one of the accepted translations. The Czech team has no control over technical issues of this type.
