This paper is focused on the contribution of phonetic tools used in prosody analyzes for the study of stuttering. Three contrasted subjects (1 Non Stuttering Person, NPS and 2 Person Who Stutter, PWS with contrasted stuttering profiles) have been recorded while performing a map task under varying auditory feedback conditions (NAF, DAF 80, DAF 120 and DAF 160). The fluency index used (ISI) reveals differences between subjects and conditions, and therefore appears as a possible tool for use in further research aiming at a better understanding of stuttering and/or at the development of reliable assessment methods is discussed.
