Speaking English Clearly in University Seminars and a Viva

A university seminar and a viva voce both ask something that ordinary conversation doesn't: think and speak at the same time, in front of people evaluating you, often in your second language, with no script to fall back on. That combination is genuinely harder than either prepared public speaking or casual conversation, and it deserves its own kind of practice rather than being lumped in with general fluency work.

30-second version: Rehearse defending a position out loud, unscripted, under a self-imposed time limit — that's the actual skill a seminar or viva tests, and it's trainable separately from knowing your material.

Why does knowing the material well not guarantee speaking about it well?

Because a viva or seminar tests real-time retrieval and explanation under pressure, not just understanding. You can know a concept thoroughly and still stumble explaining it live, the same way a software engineer can solve a problem silently but struggle to narrate the solution out loud under time pressure — the same gap shows up in technical interviews. The fix in both cases is rehearsing the explaining, separately from the studying, because they draw on different skills.

How should I practise for unpredictable follow-up questions?

Simulate them yourself. Pick a claim from your own work, state it out loud, then immediately ask yourself the obvious challenge — "why not the alternative explanation?" — and answer that out loud too, unscripted. This mirrors how a viva or seminar discussion actually unfolds: a position, then a probe, then a real-time defence. Recording this and listening back for pace is revealing, because most people speed up defensively under a challenge, which is exactly when clarity matters most.

What does an examiner or seminar audience actually listen for?

Whether you land on a clear position rather than a hedge-filled list of considerations, and whether your pace stays composed when a question is unexpected. sayit's consulting interview page describes a closely related skill — landing on a clear recommendation rather than a balanced list, and handling being interrupted or redirected mid-answer — which is nearly identical to what a strong viva answer needs, even though the setting is academic rather than professional.

A short rehearsal routine before a seminar or viva

1. 1.Pick three likely challenge questions to your own argument.
2. 2.Answer each out loud, recorded, in under a minute — force yourself to land on a position, not a survey of options.
3. 3.Listen back for pace, specifically whether it sped up on the hardest question.
4. 4.Repeat the hardest one at a deliberately steadier pace.

Does pronunciation actually matter in an academic discussion?

Less than pace and structure, but it still matters on the specific technical terms central to your work — the words you'll repeat throughout the discussion. A slipped sound on a term you use constantly compounds across a long viva in a way a one-off slip on an ordinary word never does, so it's worth a few dedicated passes on your own field's vocabulary specifically, the same logic that applies to a technical interviewer listening for consistent, jargon-free explanation.

How is a viva different from a seminar, practice-wise?

A viva is usually higher-stakes and more adversarial by design — examiners are specifically trained to probe weak points in your argument, where a seminar discussion is more collaborative and shared among peers. That difference matters for practice: rehearsing calm, composed delivery under a genuinely challenging follow-up question matters more for viva prep specifically, while a seminar rewards being comfortable thinking out loud in front of a group without every question being an attack on your position. Practising both — a friendly discussion and a harder cross-examination — covers the range you'll actually meet.
