SPEECH LANGUAGE AND HEARING, 2024 (ESCI)
Phonological processes are examples of normal simplified articulation seen in all children during the language and speech sound acquisition phase, and their frequency decreases and disappears with age. They are of concern when they are used beyond the expected time frames or when the simplification processes do not follow the typical substitutions. The aim of this study was to examine the phonological development and consonant acquisition of Turkish-speaking children with CI and compare the results with normative data. Comparisons were made according to the duration of CI use and also according to the age of CI. Therefore, 52 participants were analysed, first divided into 4 groups according to duration of CI use and then into 2 groups according to age of CI. Phonology skills were evaluated with the Bankson-Bernthal Phonology Test. In children with CI, 1373 consonant production errors were detected. There were 28 phonological processes corresponding to these errors. The most common phonological processes were Initial Consonant Deletion, Cluster Reduction, Final Consonant Deletion, Vowel Lengthening, Devoicing, Assimilation, Nasalization and Dentalization. The most errors occurred in fricative and voiced sounds, and the fewest errors occurred in bilabial consonants (/b,/p,/m/). This study demonstrated that CI performed before the age of three years and continued use of CI over an extended period of time have beneficial impacts on the development of phonological skills. This study is thought to enhance the existing research on the acquisition of consonants and phonological development in Turkish-speaking children with CI, a topic that currently lacks sufficient information.
