Mood and Speech Acts in Broadcast Media Discourse: A Case Study of Radio Nigeria’s Network News Bulletin

Language in broadcast news functions as a strategic tool for performing social actions, constructing authority, and guiding public behaviour. This study investigates how Radio Nigeria’s Network News Bulletin deploys speech acts to meet communicative and institutional goals. Anchored in Searle’s Speech Act Theory, it explores how news language simultaneously informs, persuades, regulates civic conduct, and legitimises authority. The research adopts a qualitative case study design to enable in-depth examination of speech acts within natural broadcast contexts. One month of news bulletins was purposively sampled, audio-recorded, and transcribed. Supplementary interviews with news anchors offered insider perspectives on intentional language choices and audience engagement. Data were analysed descriptively using Searle’s five categories—assertives, directives, commissives, expressives, and declaratives. Each utterance was coded to identify how language constructs factual reporting, encourages compliance, projects future action, expresses sentiment, or enacts institutional authority. Ethical procedures, including institutional permission and interviewee anonymity, were strictly followed. Findings reveal that assertives dominate, reflecting the centrality of factual reporting and epistemic authority, particularly in security alerts, government activities, and humanitarian updates. Indirect directives emerged prominently, guiding civic behaviour through persuasive appeals. Commissives and declaratives signalled institutional commitments, while expressives conveyed emotional solidarity. Future research should compare speech-act patterns across stations and programme genres. Received: 22 November 2025 / Accepted: 29 December 2025 / Published: January 2026
