The two situations are not the same
Chris Anderson's TED Talks and Dale Carnegie's work on effective speaking are genuinely good books. They are about performance: a prepared talk, delivered to an audience, rehearsed until it lands.
A speaking test is the opposite situation. It is unrehearsed, it is a conversation, and the examiner is specifically listening for evidence that you are producing the language now rather than reciting it.
What backfires
| Presentation technique | Why it costs you in a test |
|---|---|
| A rehearsed opening | A polished, memorised first thirty seconds followed by a sudden drop in fluency is the clearest possible signal that the opening was learned. It draws attention to the join. |
| A prepared answer, delivered regardless | The examiner asked a specific question. A recited Part 2 answer that does not fit it fails Task Response and reads as memorised. |
| Dramatic pauses | Pauses are measured for hesitation. A theatrical pause and a hesitation pause are hard to tell apart from the outside. |
| A performative, projected voice | It sounds like a speech, not an answer. The test is a conversation, and it is marked as one. |
| Rhetorical flourishes | Imagine a world where… in a Part 1 answer about your hometown reads as a rehearsed set piece. |
None of these are bad speaking. They are bad for this situation, which is a different thing.
What genuinely transfers
Now the good half, and it is worth a lot.
| From the books | Why it raises your band |
|---|---|
| Every talk needs one idea | The same is true of a two-minute answer. One idea, developed, beats four ideas listed — and development is exactly what Fluency & Coherence and Task Response reward. |
| Concrete examples beat abstractions | A specific, real detail is worth more than three general sentences. It develops your point, and it gives you something to say, which removes the hesitation caused by having nothing. |
| Structure before you speak | Point, reason, example. It is a smaller version of what Anderson calls a through-line, and it turns a rambling answer into a coherent one. |
| Tell a small story | Narrative is easy to produce fluently, because you are not searching for language — you already know what happened. It naturally generates past tenses and complex sentences. |
| Slow down | Carnegie is right, and so is the score: rushing produces stumbles, and stumbles produce hesitation inside phrases, which is what actually lowers Fluency. |
The delivery paradox
The books tell you to rehearse until the delivery is smooth. The test penalises rehearsal. That looks like a contradiction, so it is worth being precise about what your delivery should actually be.
Natural, and slightly imperfect. A real speaker thinking in real time restarts occasionally, says "um", and pauses to choose an idea. All of that is normal at every band, including the top ones. What is not normal — and what stands out immediately — is a first minute that sounds like a recording followed by four minutes that sound like a person.
This shows up in the measurements as well as to the ear. A rehearsed passage has a very different pause structure from spontaneous speech, and the transition between them is audible.
So: prepare ideas, not sentences. Practise the structure until it is automatic; never practise the wording until it is fixed. See how to stop hesitating.
For the test, and for real life
For the test: take the structure, the concrete example and the one-idea discipline. Leave the rehearsed delivery, the projected voice and the dramatic pause at the door. Sound like a person having a conversation, because that is what is being marked.
For real life: TED and Carnegie are among the best training available for presenting, and presenting is a skill that will matter to your career for decades after this test is forgotten. When you have a talk to give, rehearse it — properly, out loud, many times. That is exactly right in that room.
Two rooms, two modes. The books are not wrong; they are simply answering a different question from the one the examiner is asking.
Frequently asked questions
Can I use public-speaking techniques in IELTS Speaking?
Some of them. Structure, one clear idea, concrete examples and slowing down all raise your band. Rehearsed delivery, a projected performing voice and dramatic pauses all work against you, because a speaking test is an unrehearsed conversation and memorised language is penalised.
Is it bad to prepare answers in advance?
Prepare ideas, not sentences. Practising a structure until it is automatic is good preparation. Practising wording until it is fixed produces a recited answer — and a polished memorised opening followed by a sudden drop in fluency is one of the most detectable things in the whole test.
Should my delivery be smooth and polished?
It should be natural. Real speakers thinking in real time restart occasionally, hesitate and pause to choose ideas — all of which is normal at every band, including the top ones. What stands out is a first minute that sounds like a recording and four minutes that sound like a person.
Are TED Talks worth studying for English?
For presenting, yes — it is excellent training and a skill that lasts long after the test. For a speaking exam, take the structure and the concrete examples and leave the rehearsed delivery behind. The books are answering a different question from the one the examiner is asking.
