Observations of velopharyngeal closure mechanism in horizontal and lateral direction from fiberscopic data
Résumé
The present study is concerned by the spatio-temporal
coordination between the movements of the lateral pharyngeal walls (LPW) and the movements of the velum. There are two objectives: first, to investigate velum and LPW movements, and second to determinate if there is a correlation between these movements in the production of the velopharyngeal mechanisms in speech. It was found that for our two subjects, there was a close correlation between velum and LPW movements. It was also discovered that the movements for opening the
velopharyngeal path for a nasal vowel was influenced by
the identity of the preceding oral vowel, independently
from the intervening consonant, and that there was vowel to vowel assimilation for what concerns the studied movements.
