Abstract
To compare the tongue contour in different groups (children with typical, atypical phonological development and adults) in the production of fricative children, through ultrasound videos. The six participants were divided in three groups: Group DF - two children with phonological processes anteriorization of fricative (/ʃ/→ [s]), (both with seven years), group DT - two children with typical development of language (eight and nine years old) and group AD - two adults, all speakers of Brazilian Portuguese. The videos of the movement of the tongue in the production of target sounds inserted in the words /'sapo/, /'sika/, /'suko/, /'∫ave/, /'∫ike/ and /'∫uva/ were organized and evaluated by three judges speech therapists with experience in this area, guided in VAS. It has been observed that, for two of the judges, there was a significant difference between the words produced by children with DF and CT when compared with the words in contexts and vowel [i] and [u], and the productions of these children /∫/→[s] and /s/→[s], respectively, but not for words accompanied [a]. When comparing the data of children with DF and AD, there was statistically significant (p-value < 0.05) in the context of vowel [u]. The judges have detected articulatory differences between typical and atypical productions for children, as well as differentiation also as to the production of adults.
