treatment effect with a stimulability and segment complexity strata model with speech intervention software (SI FALA).
Analysis of the distinctive features and of the phonetic and phonological systems in different severities of phonological disorder
(ii) Do children with a phonological disorder
prefer to use any acoustic parameters?
The results of this study are consistent with previous research that has demonstrated that children with phonological disorders
perform more poorly on phonological awareness tasks than do children without phonological impairments (Bird et al., 1995; Catts, 1991a; Catts et al., 1999; Cowan & Moran, 1997; Larrivee & Catts, 1999; Magnusson & Naucler, 1993; Rvachew et al., 2003; Vellutino & Shub, 1992; Webster & Plante, 1992).
Thus, further research studies concerning that variable are suggested, distinguishing phonetic disorders from phonological disorders
so that the subject is elucidated.
Comparison of degrees of phonological disorders
in two moments, in Evaluations 1 and 2 Av2 Av2 Light 15,8% 31,6% Slightly moderate 21,1% 26,3% Moderately severe 26,3% 36,8% Severe 36,8% 5,3% Legend: (Av1) Assessment 1 and (Av2) Assessment 2.
These results also suggest that practitioners should consider the position of stress in words when working with children, as this may enhance progress in the treatment of children with phonological disorders
The sample  consisted of a corpus of speech samples obtained from the first phonological assessment of 58 individuals with phonological disorders
. A total of 21,619 words were analyzed using the VARBRUL 2S statistical package.
The explanation for this difference is that in the referred study , the author researched children with phonological disorders
, while our research is about children with typical phonological acquisition in a wide age group, in addition to differences in terms of methodological issues.
Measurement of phonological disorder
severity is an important information to be considered in clinical practice as it can be used to monitor the progress during therapy treatment.
