Introduction
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 ((NAM;
SALTZMAN, 2003; GOLDSTEIN et al., 2007). 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.
Methodology
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) (ARTICULATE INSTRUMENTS,
2012).
Analysis
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.
