Section I

Why Speaking Skill Matters at the Tertiary Level

Public speaking is consistently ranked among the most important academic and professional competencies expected of university graduates (Lucas, 2020, p. 4). At the tertiary level, students are required to give seminar presentations, participate in oral examinations (vivas), contribute to panel discussions, and deliver research findings — all of which demand confident, organised, and intelligible spoken English (Bailey, 2018, p. 6).

Yet surveys consistently reveal that communication apprehension — commonly called stage fright — is among the most widely reported anxieties among students, including at Nigerian universities (Okafor, 2021, p. 34). This lecture addresses both the structural and psychological dimensions of effective public speaking.

Key Concept
Public Speaking
The process of communicating a prepared or semi-prepared message to a defined audience with a specific purpose — to inform, persuade, or inspire (Lucas, 2020, p. 6).
Communication Apprehension
A level of fear or anxiety associated with real or anticipated communication with others. It is a normal and universal experience, not a personal failing (McCroskey, 2019, p. 8).
Section II

Preparing a Speech — Structure and Planning

Effective public speaking begins long before a speaker stands before an audience. Preparation is the single most reliable strategy for reducing anxiety and improving delivery (Lucas, 2020, p. 22). A well-prepared speech has three essential components: a clear structure, audience awareness, and a defined purpose.

The Classical Three-Part Structure

Every effective academic speech or presentation follows the same fundamental structure — a structure that has been documented since classical rhetoric (Perloff, 2021, p. 44):

PartPurposeKey ElementsApproximate Length
Introduction Capture attention, establish credibility, state the topic and purpose, and preview the main points (Lucas, 2020, p. 180). Attention-getter · Thesis statement · Preview of main points 10–15% of total time
Body Develop the main arguments or information in a logical, organised sequence with supporting evidence (Bailey, 2018, p. 24). 2–4 main points · Supporting evidence · Transitions between points 70–80% of total time
Conclusion Signal the end, restate the thesis in different words, summarise the main points, and leave a memorable closing impression (Perloff, 2021, p. 52). Summary · Restatement of thesis · Memorable closing line or call to action 10–15% of total time
Audience Analysis
Know Your Audience
Before writing a word, ask: Who are they? What do they already know about this topic? What do they need to know? What will interest or concern them? Academic presentations for fellow students differ from those delivered to lecturers or external examiners (Lucas, 2020, p. 30).
Purpose
Every speech has one of three primary purposes: to inform (present new knowledge), to persuade (change attitudes or behaviour), or to inspire (motivate and move). The purpose shapes every other decision in the preparation process (Bailey, 2018, p. 14).
Section III

Delivery Techniques — Verbal and Non-Verbal

A well-structured speech delivered poorly will fail. Delivery is the vehicle through which the content reaches the audience, and it operates on two channels simultaneously — verbal and non-verbal (Lucas, 2020, p. 240).

Verbal Delivery

🎙️
Volume
Speak loudly enough to be heard by all audience members, including those at the back. Vary volume for emphasis — lowering the voice can be as powerful as raising it (Bailey, 2018, p. 34).
⏱️
Pace
Speak at a rate that allows the audience to absorb content — approximately 120–150 words per minute for academic presentations. Slow down for complex ideas; pause for emphasis (Lucas, 2020, p. 246).
🎵
Pitch and Intonation
Vary pitch to convey meaning and maintain audience attention. A monotone delivery — regardless of content — causes audiences to disengage within minutes (McCroskey, 2019, p. 52).
✂️
Clarity and Articulation
Pronounce words fully and clearly, particularly final consonants. Avoid mumbling, swallowing syllables, or running words together. Apply the phonological principles from Module 1 (Perloff, 2021, p. 62).

Non-Verbal Delivery

👀
Eye Contact
Maintain regular eye contact with different sections of the audience — not just the examiner or one person. Eye contact signals confidence and keeps the audience engaged (Lucas, 2020, p. 255).
🧍
Posture and Stance
Stand upright with feet shoulder-width apart. Avoid swaying, slouching, or pacing nervously. A grounded, open stance projects authority and confidence (Bailey, 2018, p. 42).
🤲
Gestures
Use purposeful hand gestures to reinforce key points, show size or direction, or emphasise contrast. Avoid repetitive, nervous gestures such as fidgeting or gripping the lectern (McCroskey, 2019, p. 60).
😊
Facial Expression
Your face must match your words. A speaker who discusses a problem while smiling sends a contradictory message. Facial expressions communicate emotion, sincerity, and engagement (Perloff, 2021, p. 68).
📌

The 7-38-55 Principle: Research by Mehrabian (cited in Lucas, 2020, p. 242) suggests that when verbal and non-verbal messages conflict, audiences rely primarily on non-verbal cues to determine meaning. Content alone is not enough — how you deliver it matters enormously.

Section IV

Managing Stage Fright

Communication apprehension — the anxiety of speaking before an audience — is experienced by over 75% of people at some point in their lives (McCroskey, 2019, p. 12). The goal is not to eliminate anxiety entirely — a moderate level of arousal actually improves performance — but to manage it so it does not disrupt delivery (Lucas, 2020, p. 58).

Strategy 1 — Preparation
Know your material thoroughly
The single most powerful anxiety-reducer is thorough preparation. When you know your content deeply, the fear of forgetting diminishes substantially. Practise your speech aloud at least three times before delivery (Lucas, 2020, p. 60).
Strategy 2 — Reframing
Reframe anxiety as energy
The physiological symptoms of anxiety — elevated heart rate, heightened alertness — are identical to the symptoms of excitement. Consciously reframe the feeling as positive energy and readiness, not threat (McCroskey, 2019, p. 20).
Strategy 3 — Audience Focus
Shift focus from self to audience
Most anxiety is self-centred — the speaker is focused on how they appear rather than on delivering value to the audience. Deliberately shifting focus outward to the audience and their needs reduces self-consciousness (Bailey, 2018, p. 52).
Strategy 4 — Physical Regulation
Use controlled breathing
Slow, deep diaphragmatic breathing before and during a speech reduces cortisol and activates the parasympathetic nervous system — the body's calming mechanism. Take three deep breaths before beginning (Perloff, 2021, p. 80).
Strategy 5 — Experience
Speak frequently and deliberately
Public speaking anxiety decreases with exposure. Every presentation — however imperfect — builds confidence for the next. Seek opportunities to speak: seminars, church, community meetings, student groups (Lucas, 2020, p. 65).
Section V

Practical Activity
Speaking Skills — 10 Scenario Questions

For each scenario or question below, identify the relevant speaking principle, strategy, or error. Write one sentence justifying your answer.

    Think: inform, persuade, inspire.
    3 Purposes

    What makes a memorable conclusion?
    Weak Conclusion

    Why does Module 1 (Phonetics) remain directly relevant to spoken academic presentations?
    Connect pronunciation competence to presentation delivery.

Section VI

Conclusion & Key Takeaway

Effective public speaking is not a talent — it is a skill built through deliberate preparation, structured delivery, and repeated practice. A student who structures every presentation with a clear introduction, body, and conclusion; who controls pace, volume, and eye contact; and who manages anxiety through preparation and audience focus will consistently deliver compelling academic presentations (Lucas, 2020, p. 70).


The phonological competence developed in Module 1 — clarity of pronunciation, correct stress placement, and appropriate intonation — is the acoustic foundation on which every delivery technique in this lecture depends. Good speaking integrates grammar, phonology, and rhetoric simultaneously (Bailey, 2018, p. 60).
