N2 - A laryngectomy is the surgical removal of the larynx which results in the loss of phonation. The aim of this study was to characterize tongue and lip movements during speech produced by individuals who have had a laryngectomy. EMA (electromagnetic articulography) was used to derive movement data from the tongue and lips of nine speakers (four alaryngeal and five typical). The kinematic metrics included movement duration, range, speed, and cumulative path distance. We also used a support vector machine (SVM) to classify alaryngeal and healthy speech movement patterns. Our preliminary results indicated that alaryngeal articulation is longer in duration than healthy speakers. Alaryngeal speakers also use larger lateral tongue movements and move the tongue back at a slower speed than healthy speakers. The results from the SVM model also indicates that alaryngeal articulatory movement patterns are distinct from healthy speakers. Taken together, these findings suggest that there are differences in articulatory behavior that occur after the removal of the larynx. It may be helpful to consider the distinct articulatory motion patterns of alaryngeal speech in clinical practice and in the development of technologies (e.g., silent speech interfaces) that assist to provide an intelligible form of speech for this patient population.
