Abstract: Subjects underwent speech-language pathology and audiology screening, and then data collection for acoustic analysis. For acoustic analysis, pseudowords in carrier phrases were used. We analyzed 624 productions from the subjects, and the results were statistically analyzed. Results: The parameters frequency band of higher concentration of noise and formant transition of the following vowel presented differences between groups. In the comparison between word positions, the parameters duration and cutoff frequen… Show more

“…In the Brazilian literature, authors such as Berti (2006Berti ( , 2010, Freitas (2007), Rodrigues (2007), Melo et al (2012) and Brasil et al (2012) described the presence of covert contrasts in the productions of children -with and without phonological disorders -, corroborating international studies on the omnipresence of covert contrasts (SCOBBIE, 1998). In general, the findings obtained from these studies revealed that acoustic cues used by children to mark contrasts may vary in terms of type and magnitude.…”

(KENT;READ, 1992, p.108). articulatory analysis, that the speaker is systematically producing differences to distinguish two phonemes (MACKEN;BARTON, 1980;SCOBBIE, 1998;HEWLETT;WATERS, 2004;BERTI, 2006;FREITAS, 2007;RODRIGUES, 2007;BERTI, 2010;MELO et al, 2011;BRASIL et al, 2012). Scobbie (1998) performed an extensive bibliographic survey of all the authors who described the presence of the covert contrast, both among children with typical development and among children with a phonological disorder.…”
