Viva voce

Also called Viva · Oral examination · Authorship interview

A viva voce is an oral examination in which you are asked to discuss and defend work you submitted, used in academic misconduct procedures to establish whether you can account for what you wrote.

Last reviewed 15 August 2026 · The HumanFlow team

In plain English

A conversation about your own essay, with someone who has read it, asking why you made the choices you made.

It is not a memory test. Nobody expects you to recite your bibliography.

A worked example

The kinds of question that actually get asked, and what each one is testing.

"Why did you structure it this way rather than chronologically?"
        → tests whether the structure was a decision

"This source on page four — what does it actually argue?"
        → tests whether the sources were read

"You changed position between sections two and four. Why?"
        → tests whether you know your own argument

"What did you cut, and why?"
        → tests whether there was a drafting process at all

Every one of these is answerable in a sentence or two by someone who did the work, including someone who found it difficult and did it badly.

The last question is the most revealing and the hardest to anticipate. Anyone who wrote a real draft threw something away and remembers being annoyed about it.

Notice that none of them asks you to prove a negative. That is the structural advantage of a viva over a detection score: it examines what you know rather than what a number implies.

Why it matters for AI detection

Where a viva is available, it is usually the fairest route open to you, and it is worth asking for one. A conversation produces evidence about your understanding; a percentage produces an inference about your text.

It is also increasingly the recommended procedure. Guidance in this area has moved towards treating detection output as a trigger for enquiry rather than as evidence in itself, and an oral examination is the enquiry.

Prepare by rereading your own work and your notes, not by rehearsing answers. The questions are about decisions you made, and the honest recollection of a decision sounds different from a rehearsed one.

Commonly confused with

Appeal
A viva is a way of gathering evidence, usually before or during a decision. An appeal challenges a decision that has already been made. Being offered a viva is not a finding against you.
Thesis defence
The same words describe the doctoral examination, which is a scheduled academic milestone rather than an integrity procedure. Context tells you which one is meant, and confusing them causes unnecessary alarm.
