The Phonological Development in the Speech of Children of Collo at SkikdaSpeechCommunity

Abstract

This study investigates phonological acquisition patterns among preschool children (ages 3–5 years, n=20) from the Collo dialect region in Skikda, Algeria, applying Optimality Theory (OT) as the primary analytical framework. Speech data were gathered through standardized picture-naming tasks using 26 black-and-white line drawings depicting culturally familiar concrete objects—such as animals (dog, cat), food items (orange, carrot), and household goods (chair, cup, shoes)—alongside repetition of 10 carefully selected target words that varied systematically in syllable structure (CV, CVC, CCVC, CVCC) and included challenging phoneme sequences and consonant clusters typical of Collo Arabic. All samples received narrow phonetic transcription, enabling detailed descriptive analysis that identified seven distinct phonological processes: assimilatory types (consonant harmony, initial consonant voicing, manner assimilation) and non-assimilatory types (consonant cluster reduction, weak syllable deletion, vowel epenthesis, fronting, backing).Findings revealed pronounced age-based differences: younger children (3–4 years) displayed elevated frequencies of assimilatory processes—for instance, consonant harmony occurring at 100%—driven by markedness constraints that prioritize phonological simplification in immature grammars. In contrast, older children (4–5 years) demonstrated substantially reduced rates across nearly all processes, consistent with OT's core mechanism of constraint reranking, whereby faithfulness constraints progressively outrank markedness ones to produce increasingly faithful adult-like outputs. Non-assimilatory phenomena, including cluster reduction guided by the Sonority Sequencing Principle, persisted across groups but similarly declined with maturation, highlighting unique Collo dialectal characteristics.Although constrained by a modest sample size and single-session protocol, these results provide essential baseline descriptive data on Collo phonological development. They illuminate systematic progress toward target phonology and affirm OT's robustness in modeling dialect-specific acquisition trajectories.
