How to practice a TEDx talk

Know the rules first

TEDx events run under rules set by TED, and a few of them shape how you prepare (TEDx rules):

• Time. TEDx talks are typically under 18 minutes, and TED notes that 3 to 9 minutes is often ideal for a focused idea. Your organizer gives you a slot, so plan to finish inside it with room to spare.
• No selling. Speakers cannot promote their own products, books or businesses, or their employer's.
• Claims need support. Scientific claims should rest on data that experts in the field have scrutinized.

Ask your organizer for your exact time slot and when their rehearsals happen, since many run their own.

Get your idea into one sentence

A TEDx talk is built around one idea. TED describes a good one as either something new and surprising, or a familiar idea argued in a way that challenges what people believe, and notes that a story or a list of facts is not an idea on its own (what is a TEDx talk). If you cannot say yours in a sentence, the talk will try to do too much. Write that sentence at the top of your script and check every section against it. If a part does not help the idea land, cut it, however good it is.

Build it around a story

Talks that land tend to move like a story, with something at stake and a turn, rather than reading as a list of points. A personal stake or a concrete example carries an idea further than a statistic on its own. You do not need a dramatic life story. You need one specific moment where the idea became real for you.

Write the opening and the ending early

The first 30 to 60 seconds decide whether people lean in. Open with a question, a scene, a surprising claim or what is at stake. Thanking the organizers, listing your credentials or walking through an agenda spends that window on something nobody came for.

The ending is what people repeat afterward. Land your idea on a line or an image worth remembering. A talk that trails off, or stops on a flat "thank you", gives away the moment you spent the whole talk building toward.

Rehearse out loud, again and again

Reading your script silently is editing. Rehearsing means saying it out loud, standing up, from the very first run.

TED's advice to organizers is that speakers should run through the talk until they no longer have to think about the fact that they are reciting a script (TEDx rehearsals guide). Remembering every word matters less than knowing the talk well enough that it sounds like you are thinking it for the first time. The same guide suggests recording yourself, transcribing it, editing and repeating. Hearing yourself is the quickest way to find the sentences you stumble over.

Time every run. If you are right at your limit in rehearsal, you are likely to run over on the day, because a live audience adds pauses that an empty room does not.

A rehearsal plan

Every event runs on its own schedule, so stretch or squeeze this to fit yours.

What to check on every run

• Time: are you inside your slot, with room to spare?
• Your idea: does it come through clearly enough that a listener could repeat it?
• Opening: does the first minute earn attention?
• Pace: do you slow down for the lines that matter? Our guide to speaking pace covers what to listen for.
• Pauses: do you stop after your key lines, or rush past them?
• Filler words: do they bunch up at your transitions? See how to stop using filler words.
• Close: does your last line land the idea?

How PitchCoach AI scores a TEDx talk

Pick TEDx talk as your speech type and PitchCoach AI grades your recording against what makes a TEDx talk work. Alongside the usual report you get five scores, each with a note:

• One Big Idea: is the whole talk built on a single idea you could state in a sentence?
• Narrative Arc: does it move like a story, with tension and a turn, rather than a list of points?
• Opening Hook: do the first 30 to 60 seconds earn attention?
• Emotional Resonance: does it make people feel something, through honesty and vivid specifics?
• Memorable Close: does the ending land the idea on a line worth remembering and repeating?

A session can run up to 20 minutes, so a full talk fits in one recording. Record each rehearsal, and every new report compares your scores with your average so far.
