The topic of the present paper rises from our preceding experiments with natural sentences and it is a part of our longterm research concerning the role of duration and intensity in synthetic speech. We assume that these two parameters play a part not only on the rhythmical and phonostylistic levels, but also act, together with the intonation, on the modal level (difference between a statement, a question, an order etc.). We tested three short informative sentences with seven different intonation patterns in four variants for the presence/absence of variation of duration and intensity. The F0 curbs show a perception symmetricity shifted toward the assertive pole. As far as the role of duration and intensity is concerned, they turned out to contribute slightly to keeping the categories assertive/interrogative apart.
