The aim of this paper is to show that prosody relates directly to discourse interpretation. In an experimental framework of 36 readings of a text, and using a segmented and labelled data base, we intend to show that speakers adapt their prosody, and especially F0 organization, rather precisely to the linguistic content of the significates and to the communicative situation. Among the various possibilities of comprehension that the text allows, one is selected by the speaker. Then the marks of personal interpretation that the speaker invests in the text are supplied by F0 structuration and by specific F0 indices. This paper shows the main F0 strategies of interpretation that speakers provide, using cocepts from linguistics and psycholinguistics.

Keywords: linguistic modelization, F0 indices, discourse interpretation
