This paper investigates to what extent statements, Wh-questions, Yes/No-questions and declarative questions in Dutch can be automatically discriminated on the basis of global and local F0-parameters. Global parameters were the slope and mean pitch of upper and lower trend lines that were fitted through F0-curves; local parameters were onset and offset F0 of a terminal question-marking pitch rise. Results indicate that women mark the interrogative status of a sentence more often and perceptually more saliently. Generally, global downtrend parameters are better predictors of sentence type than parameters of the final rise.
