The impact of intergenerational transmission on phonological continuity in Yoruba in Osun State

The impact of intergenerational transmission on phonological continuity in Yoruba in Osun State

Background of the study
Intergenerational transmission is a vital process for the preservation and evolution of language, particularly in culturally rich communities such as the Yoruba in Osun State. This study investigates how traditional oral practices and familial language use ensure the continuity of phonological structures in Yoruba. As younger generations encounter modern influences, the mechanisms of language transmission are simultaneously challenged and reinforced through daily interactions and cultural rituals (Adekunle, 2023). The Yoruba language, known for its tonal complexity and rhythmic patterns, provides an ideal case study for exploring how phonological continuity is maintained across generations. Contemporary research has shown that despite the pressures of globalization, strong familial bonds and community practices play a crucial role in preserving linguistic norms (Opeyemi, 2024). This research contextualizes intergenerational transmission within sociocultural frameworks and examines the interplay between traditional education and modern media influences. It further investigates how language shift, when it occurs, impacts phonological integrity and contributes to the broader discourse on language preservation. The study’s findings are expected to highlight the resilience of indigenous phonological systems amidst socio-cultural change, thereby informing both linguistic theory and community-based language planning (Balogun, 2025).

Statement of the problem
Despite the acknowledged importance of intergenerational transmission in sustaining linguistic heritage, empirical data on its impact on Yoruba phonology remain limited. Many families in Osun State face challenges as modern lifestyles and media consumption alter traditional modes of language teaching (Adekunle, 2023). There is uncertainty regarding whether these changes facilitate a loss of phonological precision or whether they support a dynamic evolution of language. The existing literature often overlooks the subtle effects of familial language practices on phonological continuity, leaving educators and policymakers without clear guidelines for preservation (Opeyemi, 2024). This study seeks to address these gaps by examining how intergenerational transmission either reinforces or disrupts the phonological system of Yoruba, thereby contributing to improved language maintenance strategies (Balogun, 2025).

Objectives of the study:

1. To assess the role of intergenerational transmission in maintaining Yoruba phonological continuity.

2. To identify changes in phonological patterns attributable to modern influences in Osun State.

3. To evaluate strategies that support effective language transmission within families.

Research questions:

1. How does intergenerational transmission affect the phonological continuity of Yoruba in Osun State?

2. What modern influences are evident in the phonological adaptations observed among younger speakers?

3. Which familial and community practices most effectively preserve traditional phonological features?

Research Hypotheses:

1. Strong intergenerational transmission positively influences the maintenance of Yoruba phonological structures.

2. Modern influences contribute to subtle phonological shifts among younger speakers.

3. Traditional practices are critical in mitigating phonological erosion in the language.

Significance of the study:
The study is significant as it provides a comprehensive understanding of how intergenerational language practices influence Yoruba phonology. It offers valuable insights for educators and community leaders seeking to preserve linguistic heritage. The outcomes are expected to inform effective language planning and cultural preservation initiatives, ensuring continuity in a rapidly modernizing society (Adekunle, 2023; Balogun, 2025).

Scope and limitations of the study:
The study is limited to exploring intergenerational transmission and its effect on the phonological continuity of Yoruba in Osun State. It focuses on familial and community practices without extending to formal education settings or other regional dialects.

Definitions of terms:

1. Intergenerational Transmission: The process by which language and cultural practices are passed from one generation to the next.

2. Phonological Continuity: The consistent maintenance of sound patterns over time within a language.

Yoruba: An indigenous language of Nigeria known for its tonal and rhythmic features.
