Abstract

_______________________________________________________________________________________________ Spatio-temporal coordinations in Moroccan Arabic ab(bi) sequences In this study using 3-dimensional EMA (AG500 Carstens Medizinelektronik) we tried to characterize the temporal relations between consonant and vowels in [ab(b)i] contexts. We found that, [bb] has a consonantal gesture (LowerLip_y) whose total duration and plateau phase are longer and the vertical target higher compared to [b]. We also found an anticipation of this consonantal gesture in [abbi] correlated with the shortening of the acoustic duration of [a] in this context. The time interval between the vowels [a] and [i] is longer in [abbi] compared to [abi]. This result, combined with other observations, seems to support the models (ex. Articulatory Phonology) suggesting a temporal coordination between the oral gesture of a consonant with that of the adjacent vowel.

Nos résultats montrent que, comparée à /b/, /bb/ a un geste consonantique (LLIPy) dont la durée totale et la phase plateau sont plus longues, et la cible verticale plus haute. Nous avons également relevé une anticipation du geste consonantique de (LLIPy) durant [abbi] qui semble être la cause de l’abrègement de [a] dans ce contexte. L’intervalle temporel entre la voyelle [a] et [i] est plus long dans [abbi] comparé à [abi]. Ce résultat, combiné à d’autres observations, semblent en faveur des modèles (exemple de la Phonologie Articulatoire) qui posent que le geste de la consonne est coordonné temporellement avec celui de la voyelle adjacente.

Ici, elle sera focalisée sur les différences entre les relations temporelles voyelle-voyelle et consonne-voyelle dans les suites [abbi] et [abi] : [ab(b)i]. Rappelons qu’au niveau acoustique, une occlusive géminée [CjCj] intervocalique se caractérise principalement par la durée plus longue de la tenue de son occlusion comparée à sa correspondante simple, et dont le rapport varie d’une langue à une autre 225 (de 1,5 à 3 selon Ladefoged et Maddieson, 1996). Les études perceptives (exemple, Lahiri et Hankamer, 1988) montrent que, cet allongement constitue l’indice majeur de la perception d’une occlusive géminée en position intervocalique, où elle est généralement attestée dans les langues (Ladefoged et Maddieson, 1996). La production des occlusives géminées intervocaliques s’accompagne, …
