How AI Became Public Speaking's Best Rehearsal Partner

The rehearsal deficit nobody talks about

Consider, for a moment, the strange economy of how we prepare to speak.

We will happily spend nine hours fussing over a slide deck, agonising over whether the font is friendly or merely smug, nudging a logo three pixels to the left and then, in a fit of doubt, three pixels back. We will rehearse, in our heads, the exact wording of an email. We will replay an awkward conversation from 2014 with the loving attention of a film restorer.

And then, for the actual act of standing up and saying the words out loud, we allocate roughly none of that care. We "wing it." We tell ourselves we will be "fine on the day." We treat the most nerve-wracking, opportunity-defining thing we will do all quarter as the one thing that requires no rehearsal at all.

This is the rehearsal deficit, and it is everywhere. The gap is not between the confident and the anxious. It is between those who have done the reps and those who have not. Confidence, it turns out, is not a personality you are issued at birth. It is a residue. It is what is left over after you have said the thing enough times that your mouth stops betraying you.

Why rehearsal is so hard to come by

If reps are the answer, you would think we would all be drowning in them. We are not, and the reasons are achingly human.

• Other people are expensive. A good coach costs money and patience, and they cannot be summoned at eleven at night when the nerves actually arrive.

• Other people judge. Or rather, we are certain they do, which amounts to the same thing. It is hard to fumble bravely in front of an audience whose good opinion you would quite like to keep.

• The mirror is a liar. Practising alone tells you nothing useful. You cannot hear your own filler words, you cannot feel your own pace galloping away, and you are far too kind to yourself about the long, dead pauses.

So the very people who most need to rehearse are the ones least able to. The stakes feel too high to practise, which guarantees the performance stays terrifying. It is a closed loop, and most people simply live inside it, quietly declining the chances that public speaking would otherwise have handed them.

Enter the patient, tireless, gloriously indifferent machine

Here is where artificial intelligence stops being a buzzword and becomes something rather lovely: a rehearsal partner with no opinion of you whatsoever.

That sounds like an insult. It is in fact the entire point. An AI coach does not raise an eyebrow when you stumble. It does not get bored on your fourteenth attempt at the same opening line. It will not, at any point, tell anyone how that run went. It simply listens to your pace, your pauses, your "ums" and "sort ofs," the places where your voice climbs into a nervous register, and it hands the information back to you without a flicker of judgement.

Why this matters here, in Singapore, right now

This is not an abstract concern, and it is not a niche one.

Singapore runs on communication. Pitches to investors, presentations to clients, vivas and oral defences, that terrifying first internship interview, the scholarship panel, the project showcase, the moment a quiet student in the back finally has something worth saying and no practised way to say it. Our schools and institutions, rightly, are placing more and more weight on how well young people can articulate, persuade, and present. The ability to speak well has quietly become one of the most consequential and least taught skills in the country.

Founded by Her: where the theory had to stand up and speak

We were reminded of all this very vividly, and rather publicly, a short while ago.

The occasion was "Founded by Her: Pitching Her Future," a pitch event organised by NUS Women In Business, and it was precisely the kind of room that separates a tidy idea from a confident one. A line-up of student founders, each with a few short minutes, a watchful panel of judges, and an audience. No second takes, no edit button, no kindly pause while you find the word you wanted. Just you, your idea, and the unforgiving honesty of a clock.

Our own Kason and Rachel took the stage to present pitchMe, and we are quietly thrilled to say they came away with third place. We will happily admit the bronze is lovely. What mattered more was the proof of concept hiding inside the afternoon. A pitch competition is, when you strip away the lanyards and the canapes, simply public speaking with the stakes turned up. The founders who connected were not the ones with the flashiest slides. They were the ones who had clearly said their words out loud, more than once, before they ever reached that stage. Every reason we are building pitchMe was sitting right there in the room, wearing a name tag.

The evening opened with a panel of founders, Dorothy Yuan, Vivian Lee, and Tina Chopra, who were refreshingly honest about a truth that pitch decks tend to airbrush out: the entrepreneurial road is rarely a straight one. What carries you down it, they suggested, is resilience and a clear sense of purpose. We would add one humble item to that list. Down a road like that, you will be asked to explain yourself, out loud, to strangers, over and over again, on days when you feel anything but certain. The founders who can do that with confidence are not braver than the rest. They have simply rehearsed more.

So our thanks go to the organisers at NUS Women In Business for building a stage worth being nervous on, to the judges for their time and candour, to the fellow founders who made the afternoon genuinely inspiring rather than merely competitive, and to the friends who came down in person to cheer. Evenings like that are exactly why we get up and keep building. They are also a neat little argument for the whole pitchMe project: confident speaking opens doors, and everyone, not just the naturally bold, deserves a fair chance to learn it.
