1. A method of determining user interactions comprising:

  • determining speech information;

    determining discourse functions and prosodic features in the speech information;

    selecting a predictive interaction model, the predictive interaction model developed by associating discourse functions and prosodic features of a training corpus of turn annotated speech with turn information of the training corpus of turn annotated speech; and

    determining an interaction turn, in the speech information, based on the predictive interaction model and the discourse functions of the speech information and the prosodic features of the speech informationwherein the predictive interaction model accepts the prosodic features of the speech information as one input and a current discourse function of the speech information as another input and determines a likelihood that a next discourse function is associated with the interaction turn.
