PURPOSE:
to compare and analyze the influence of the characteristics of the complex onset segments in the correct production in children with typical and atypical phonological development.
METHODS:
it was analyzed the speech data of 88 children, 44 with typical phonological development and 44 atypical, aged between 2:6 to 5:3 and 5:3 to 8:0, respectively. With a corpus of 524 words in typical development and 1310 in atypical. The dependent variable had variants: correct production of complex onset, simplification for Consonant¹-Vowel with and without change of obstruent, simplification for Consonant²-Vowel, obstruent change, substitution of liquid cluster, epenthesis, metathesis and others, as compensatory lengthening. Extralinguistic variables were: gender, age and type of development and the linguistic: tone, number of syllables, syllable preceding context and ensuing; position in the word, type of liquid complex onset; articulatory point, loudness and obstruent class. The statistical analysis was by computational package VARBRUL.
RESULT:
the statistical program selected for all groups at least one of the variables: articulatory point, loudness and class of obstruent. The type of liquid cluster was significant for the unique group and atypical and type of development, to produce correct and simplify Consonant¹-Vowel with obstruent change.
CONCLUSION:
the linguistic variables related to obstruent and liquid cluster were significant to the production of Consonant-Consonant-Vowel. The variable type of development was also relevant. Showing the evidence that the acquisition of complex onset can be guided by segment and there is a difference between typical and atypical children.
