Acquisition of emphatic consonants by Ammani Arabic-speaking children

This article investigates the production of the emphatic consonants /?, d, s/ by typically developing Jordanian children. Sixty typically developing monolingual Ammani Arabic-speaking children (30 boys and 30 girls) with ages ranging from 2 to 7;11 years were recruited in a production experiment. In the experiment, they were asked to produce 18 minimal pair words with emphatic consonants and their corresponding plain coronals in all word positions. Contrary to Amayreh & Dyson (1998) and Hamdan & Amayreh (2007), >50% of Ammani Arabic-speaking children produced emphatic consonants by the age of 3, >75% produced them by the age of 4, and >90% produced them by the age of 5. Acoustically, they produce them in an adult-like manner at the age of 6 word-initially and medially and at the age of 7 word-finally. The acoustic measurements confirm that children's productions become increasingly adult-like with age. Compared with nonemphatic consonants, the appearance of emphatics tends to be delayed in Ammani Arabic. This delay in the production of emphatics, which are among the least frequently occurring consonants in Arabic, is likely due to their articulatory complexity, which involves a secondary co-articulation (the so-called pharyngealization). The current findings help clarify the developmental trajectory of children's acquisition of emphatic consonants and should be informative for both researchers and clinicians.

Automated summary

This article investigates the production of emphatic consonants by typically developing Jordanian children. The study found that more than 90% of Ammani Arabic-speaking children produce emphatic consonants by the age of 5 and their productions become increasingly adult-like with age. Compared to nonemphatic consonants, the appearance of emphatics tends to be delayed in Ammani Arabic, likely due to their articulatory complexity involving pharyngealization. These findings provide valuable insights for researchers and clinicians studying children's acquisition of emphatic consonants.
