Background of the Study
Phonological features such as intonation play a pivotal role in distinguishing meaning and expressing emotion in Nigerian indigenous speech. This study focuses on comparing the intonation patterns in Yoruba and Igbo, two of Nigeria’s major languages. Yoruba intonation is known for its melodic and tonal intricacy, while Igbo intonation, though also tonal, exhibits distinct pitch contours and stress patterns that reflect its unique linguistic heritage (Adebayo, 2023). By analyzing recorded speech samples from native speakers of both languages, the study aims to document the similarities and differences in intonation patterns. This comparative approach not only enhances our understanding of regional phonological diversity but also provides insights into how intonation contributes to cultural identity and effective communication in indigenous settings. The research further explores how modern influences, such as media and urbanization, are affecting these traditional intonation patterns, potentially leading to hybridized forms (Ibrahim, 2024; Olu, 2025).
Statement of the Problem
Despite the cultural significance of intonation in indigenous languages, there is limited systematic research comparing Yoruba and Igbo intonation patterns. Variations in intonation can lead to differences in meaning and affect mutual intelligibility among speakers (Adebayo, 2023). The absence of detailed comparative studies hinders efforts to preserve these phonological traditions amid modern influences (Ibrahim, 2024). This study addresses the gap by providing a comprehensive analysis of intonation patterns, thus offering insights into the maintenance and evolution of indigenous speech in Nigeria (Olu, 2025).
Objectives of the Study
To document intonation patterns in Yoruba and Igbo speech.
To compare and contrast the phonological features of both languages.
To assess the impact of modernization on traditional intonation.
Research Questions
What are the characteristic intonation patterns in Yoruba and Igbo?
How do these patterns differ between the two languages?
What external factors influence changes in intonation?
Significance of the Study
This study advances our understanding of Nigerian indigenous phonology by comparing Yoruba and Igbo intonation. Its findings will support language preservation efforts and inform teaching methods aimed at maintaining linguistic heritage in a modern context (Adebayo, 2023; Ibrahim, 2024; Olu, 2025).
Scope and Limitations of the Study
This study focuses exclusively on the intonation patterns of Yoruba and Igbo indigenous speech and does not cover other phonological features or languages.
