Impromptu Speaking: A 30-Second Plan and a 7-Day Drill

Impromptu speaking is any speaking you do without time to prepare: answering a question in a meeting, giving an update when your name is called, or saying a few words when a leader turns to you. It feels harder than a prepared talk because you must choose the point, pick an order and speak all at once.

This page covers the workplace moment, not the contest format with assigned topics. If you have time to plan, the four-line opening for prepared talks is the better tool.

The 30-second plan is PREP with a clock: the answer first, one reason, one real example, then the answer restated. End on the restated point, then stop talking. In What / So what / Now what, the closing line is the next step instead.

0 s -------- 8 s -------- 16 s -------- 25 s ---- 30 s
|   POINT    |   REASON   |   EXAMPLE    | POINT  |
|  16 words  |  16 words  |   18 words   | 10 w   |

At 120 words a minute, our planning assumption (10 seconds is about 20 words), 60 words take 30 seconds.

Our recommendation for a pass test, run on a recording: the first sentence contains the answer, the example has a name, number or date, and you stop by 35 seconds.

Where do you find an example in 10 seconds?

Take the first of three places that gives you a name, a number or a date: a result from your own work, a client or team moment, or a mistake and what you changed. Do not hunt for the best. To choose and shape a longer story, use our guide to storytelling in public speaking.

Pause, breathe out slowly, and repeat the question in your own words: "So the question is whether we move the release." Those three seconds stop you from opening with filler, so your first sentence can be the answer. They also start the search for an example, which you finish while you give the point and the reason.

Our recommendation is to stay still while you do it, so the pause looks deliberate rather than nervous. Posture is covered in our body language self-audit. If nerves are the bigger problem, our ladder for long-term fear of speaking covers breathing and practice over weeks.

Our recommendation: use PREP (Point, Reason, Example, Point again) when someone asks for your view or a decision, What / So what / Now what when you are explaining something to a group, and Past / Present / Future when you are asked for a status.

The table below shows the match for each situation.

Matt Abrahams of Stanford Graduate School of Business teaches What / So what / Now what. What is your key idea, stated plainly. So what is why it matters to this audience. Now what is what you want them to think, feel, or do. A Toastmasters article from September 2023 applies it to speaking in the moment. Past / Present / Future, also taught by Toastmasters, covers how something was, how it is, and how it will be.

If two structures fit, pick the one whose first words you already know.

Pick one of four moves and say it calmly.

• Clarify: "Do you mean this quarter or the full year?"
• Bridge: "I do not have that figure to hand. What I can tell you is where the delay started."
• Say what you do know: "What I know is the vendor confirmed the ninth. I do not yet know whether the second batch is affected."
• Defer with a time: "I will check and send it by 5 p.m."

Here are four impromptu speaking examples, each about 60 words, roughly 30 seconds at 120 words a minute. All four are invented for illustration; every date and figure is made up.

How do you answer an unexpected question in a review meeting?

Your manager asks, "Why did this slip?" and you have no slide for it. Structure: Past / Present / Future. Sample answer (invented for illustration):

Pass check: The first sentence names the cause, a date appears, and the last sentence gives the dated commitment.

How do you answer on a client call when you have no notes?

The client asks, "Can you add the dashboard before launch?" Structure: PREP. Sample answer (invented for illustration):

Pass check: the answer, no, comes first; a comparable past job is named; and the last sentence restates the plan with a next step. If the client's new lead then asks who you are, use the script in how to introduce yourself professionally.

How do you speak when asked for a few words at a town hall?

A town hall is a meeting where leaders address a whole team or company. The leader says, "Would you say a few words about the migration?" Structure: What / So what / Now what. Sample answer (invented for illustration):

Pass check: the result comes first, one reason matters to the audience, the last sentence is the single next step, and you stop within 35 seconds.

How do you answer in a viva or when a teacher calls on you?

A viva (short for viva voce) is an oral examination. The examiner asks, "What is your main finding?" Structure: PREP. Sample answer (invented for illustration):

Pass check: the finding comes first, the limit of the evidence is stated, and the last sentence restates the point.

Record one answer a day on your phone, play it back, and score it on three pass or fail checks. Question prompts get 30 seconds, the length of the plan. Day 7 is framed as a short remark, so it gets 60 seconds. This is our recommendation, not a proven programme.

Score each recording, one point per check:

Day 5 has no answer or example to give, so it swaps checks 1 and 2 for one test: pass if your first sentence uses one of the four moves and you name what you will do next, with a time. Check 3 applies, so Day 5 is scored out of 2, not 3.

On Day 8, draw a new question prompt and run the same three checks. A pass is 3 out of 3, or 2 out of 3 if Day 1 scored 0 or 1.

Coaching is worth it when the drill passes at home but fails in front of people, or when the moment carries weight, such as a client pitch. You can build the skill alone; coaching shortens the feedback loop.

Impromptu speaking rewards order, not nerve. In the first three seconds, pause, breathe, and repeat the question. Then answer in 30 seconds: your point first, one reason, one real example, and your point again before you stop. If you do not know the answer, clarify, bridge, say what you do know, or defer with a time, and never bluff.

The shape becomes automatic only through repetition, which is why the seven-day drill matters more than any single tip. Record one answer a day, score it on the three checks, and retest on Day 8. Treat that first week as the test of whether this plan works for you.
