ARTICULATORY BEHAVIOUR DURING DISFLUENCIES IN STUTTERED SPEECH

The aim of this study is to analyse articulatory movements that occur during Stuttering-Like Dis-fluencies (SLD) and to propose a new classification of SLD based on supraglottic articulatory gestures. To carry out this study, ElectroMagnetic Ar-ticulography (EMA) data were collected within two Persons Who Stutter (PWS) reading two texts. All pathological disfluencies were identified in the production of PWS categorized as blocks, repetitions and prolongations. Results show four articulatory patterns occurring during the SLD: Reiterations of series of movements leading to sound(s) or syllable repetitions, global maintain of the articulatory posture , anarchical movements and a combination of above. While the first category only concerns repetitions , the three others can concern SLD categorized as repetitions, prolongations or blocks.
