This paper presents the first results of a semantic-pragmatic model which assigns a specific label to the relevant words of dialogue utterances and predicts their F0 value. The originality of this work lies in the kind of utterances the model has been designed for: dialogue utterances. The labels of the model represent the degrees of both the expected/unexpected and known/unknown aspects of the lexical information while the predicted value of F0 represents the corresponding weight of that information. The aim of this work is 1) to observe the real values of F0 for each label and 2) to compare the prediction of the model to the real values. The real values correspond to the 3 relevant F0 indices (Maximum F0, DF0 and mean F0). In this paper, only the levels 2 and 3 are discussed because they represent most of the population.
