Abstract Tongue motion in speech and swallowing is difficult to image because the tongue is concealed in the oral cavity. It is even more difficult to assess the extent of lingual motion quantitatively. Ultrasound imaging of the tongue in speech production and swallowing allows for a safe and non-invasive data acquisition. The paper describes the potentials and methodological problems of conducting ultrasound speech research using dynamic two-dimensional, static three-dimensional and dynamic three-dimensional ultrasound imaging.


Le mouvement de la langue pour la parole et la déglutition est difficile à mettre en image parce que cet organe est dissimulé dans la cavité buccale. Il est encore plus difficile d’évaluer l’ampleur du mouvement de la langue de manière quantitative. L’échographie de la langue lors de la production de la parole et de la déglutition constitue une méthode sécuritaire et non invasive d’obtenir des données. Le présent article décrit les possibilités et les problèmes méthodologiques pour mener des recherches sur l’utilisation de l’échographie dynamique en deux dimensions, statique en trois dimensions et dynamique en trois dimensions dans le domaine de l’orthophonie.
