Etude de disfluences dans un corpus linguistiquement contraint
Jean-Leon Bouraoui, Nadine Vigouroux.

This paper presents a study carried out on an air traffic control corpus which presents some specificity: apprenticeship situation, and the fact that the production is subordinate to a particular phraseology. Our study is related to the many kinds of disfluency phenomena that occur in this corpus, and the way they are or not affected by the nature of the corpus. We define 6 main categories of these phenomena. We then present the distribution of these categories. It appears that some of the occurrences frequencies largely differ from those observed in other studies. Our explanation is based on the corpus specificity: in reason of their responsibilities, both controllers and pseudo-pilots have to be especially careful to the mistakes they could do, since they could lead to some dramas.
