Stammering is a speech disorder involving difficulties and tensions during speech production, and characterised by episodes of audible disfluencies (repeated, prolonged or blocked sounds, disturbed rhythmic flow) (Mackay and Macdonald, 1984). Its aetiology is not yet well determined and appears to be multi-factorial (see Zmarich (2001, 2017) for a detailed review). Nevertheless, most current studies agree on the idea that it is a permanent (and not intermittent) disorder (Hultijn & Van Lieshout 1998), of neuro-motor origin (Civier et al., 2013; Max et al., 2004), modulated by various external factors such as stress, fatigue or cognitive load, ...) (Caruso et al., 1994). In this talk, I will present some of the work we have carried out as part of the StutNCo project, in collaboration with Anneke Slis, Pascal Perrier and Christophe Savarariaux. The first aim of this work was to characterise the speech gestures of people who stutter during, but also outside, episodes of disfluency, in order to identify the levels of production affected (breathing, articulation, laryngeal vibration), and to reveal any atypicalities in the coordination of these gestures, even when speech appears fluent.
