Background of the Study
Tone and stress are critical suprasegmental features that significantly influence the delivery and reception of political speeches in Nigeria. This study examines how these phonetic elements are employed by political figures in public addresses, with a focus on the nuanced variations that distinguish formal rhetoric from everyday speech (Ibrahim, 2023). In Nigerian political discourse, tone and stress not only enhance the clarity and emphasis of key messages but also serve as markers of authority, emotion, and cultural identity (Adamu, 2024). The study compares political speeches across different regions to identify patterns and deviations that reflect regional accents, audience expectations, and rhetorical strategies. Through acoustic analysis and discourse examination, the research seeks to understand how tone modulation and stress placement contribute to persuasive communication in the political arena (Yakubu, 2025). By exploring these prosodic features, the study aims to uncover the interplay between language and power, and to highlight the role of phonetic variation in mobilizing public opinion and reinforcing political legitimacy.
Statement of the Problem
There is a notable gap in research concerning the systematic appraisal of tone and stress in Nigerian political speeches. While political discourse analysis often focuses on content and rhetorical devices, the critical role of prosody in shaping public perception remains underexplored (Abubakar, 2023). This oversight hampers a comprehensive understanding of how speech delivery affects voter engagement and message effectiveness. The lack of focused studies on the phonetic dimensions of political addresses limits insights into how regional accent variations and individual speaking styles influence audience reception. Without detailed acoustic and discourse analysis, policymakers and communication experts face challenges in developing training programs that optimize speech delivery for persuasive impact (Lawal, 2024). This study seeks to address these deficiencies by rigorously examining the role of tone and stress in Nigerian public addresses, thereby filling an important research gap (Suleiman, 2025).

The findings will benefit communication trainers, speechwriters, and political analysts by highlighting effective strategies for audience engagement and message clarity. The research contributes to the broader field of political communication by integrating acoustic analysis with discourse studies (Ibrahim, 2023; Suleiman, 2025).
