Abstract

In light of Phonology Gestual the production of canonical syllables, like CV syllables, involves a pattern of coordination more stable between articulatory gestures incorporation of the consonant and vowel syllables. While the production of syllables more complexes, such as CCV, involves a gestural coordination pattern more complex and less stable. Although there are some reports in the literature that children often tend to simplify/reduce the syllabic pattern for CCV to CV, studies using acoustic-phonetic analysis have identified the presence of covert phonic contrasts in the speech of children who have not yet acquired effectively CCV syllable, which indicates that there is an effective reduction of CCV standard for the standard CV. The objective of the study is to investigate and describe, the perspective of dynamic (FonGest), the pattern of gestural coordination imbricated in the production of syllabic type CCV versus CV of children with typical and atypical phonological development. And even if the articulatory analysis provides these children the rescue of coordinations gestural imbricated in the production of consonant clusters. These project will analyse five children with phonological disorder (PD) and difficulties in the production of syllabic pattern CCV. Five children with typical language development will be analysed, according to their ages, gender and education level. The ultrasound production of each children will be analysed. Both ultrasound images of movements of the tongue and the audio signals are simultaneously obtained by means of the portable ultrasound device, coupled with appropriate equipment and software analyzed by AAA (Advanced Articulate Assistant). The results will be analyzed qualitatively as the gestural descriptors proposed by FonGest. In addition to contributions to the study of phonics acquisition it is also expected the discussion about the primitive phonological.
