Background of the study
Dialect leveling refers to the reduction of distinct regional features in language as speakers converge towards a common, standardized form. In Nigerian urban centers, where diverse dialects converge due to migration and mass media influence, phonological differences are often leveled, leading to a more homogenized speech pattern (Adeniyi, 2023). This study assesses how dialect leveling affects phonological variation by analyzing speech samples from various urban centers across Nigeria. Acoustic analysis is used to measure changes in vowel quality, consonant articulation, and prosodic features among speakers from different dialectal backgrounds. The study also examines sociolinguistic factors, such as education and exposure to national media, that contribute to leveling processes. Understanding these effects is crucial for language preservation and educational policy, as dialect leveling may lead to the loss of regional linguistic identity while facilitating mutual intelligibility in urban settings (Ibrahim, 2024). The findings will contribute to debates on standard language ideology and regional linguistic diversity.
Statement of the problem
Despite observable changes in urban speech, there is limited empirical research on dialect leveling and its impact on phonological variation in Nigerian urban centers (Chinwe, 2023). The homogenization of dialectal features may compromise regional linguistic identity and affect communication clarity in diverse urban environments. This lack of systematic analysis restricts the development of targeted language preservation and education strategies. This study seeks to fill this gap by documenting phonological differences and analyzing the extent of dialect leveling, providing a basis for informed language policy decisions.
