Phonological skills in English language learners

Area of Science:

• Linguistics
• Speech-Language Pathology
• Developmental Psychology

Background:

• English language learners (ELLs) often face challenges in acquiring native-like English phonology.
• Understanding the developmental trajectory of phonological skills in ELLs is crucial for effective intervention.
• Existing models, such as Flege's speech learning model, provide a framework for predicting phonological acquisition.

Purpose of the Study:

• To longitudinally investigate the English phonological skill development in young English language learners (ELLs).
• To analyze changes in sound class accuracy, whole-word accuracy, and phonological pattern occurrence over five time points.
• To explore the relationship between sociolinguistic variables and phonological skill acquisition in ELLs.

Main Methods:

• A longitudinal study tracking 19 ELLs aged 5;0 to 7;6.
• Assessment of sound class accuracy, whole-word accuracy, and phonological pattern frequency.
• Correlational analyses examining sociolinguistic factors like age of arrival and age of exposure.

Main Results:

• Phonological accuracy, particularly for sound classes, exceeded 90% and improved over time.
• Whole-word accuracy was high and demonstrated an increasing trend.
• Most phonological patterns occurred infrequently (<5%), with exceptions for cluster reduction, stopping, and final consonant deletion.
• Age of arrival, age of exposure, and chronological age significantly correlated with phonological skill development.

Conclusions:

• The findings support Flege's speech learning model, indicating that phonological skills in ELLs develop over time and are influenced by early exposure.
• Speech-language pathologists (SLPs) can anticipate and expect improvements in ELLs' phonological abilities, mirroring patterns seen in monolingual children.
• This study provides valuable longitudinal data for SLPs to interpret assessments of phonological skills in ELLs.
