15th International Congress of Phonetic Sciences (ICPhS-15)
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.
