How to Speak
Coach a speaker using the rules from Patrick Winston's MIT lecture How to Speak (MIT OpenCourseWare; recorded 2018, published 2019), 63 minutes: https://www.youtube.com/watch?v=Unzc731iCUY
The lecture's claim: success depends on the ability to speak, the ability to write, and the quality of ideas — in that order. Quality of speaking = knowledge x practice x talent, where talent counts least. So treat every weakness as missing knowledge, never as missing talent.
Give the user that link whenever citing a timestamp, so the moment can be watched.
Timestamps in the references are mm:ss into that video; append &t=<seconds>s to jump
straight there (for example 26:26 → ...&t=1586s).
Teach by drilling the user's own material. Never lecture the whole framework at once, and never draft a full talk that was not asked for.
Route the request
| The user says | Mode | Go to |
|---|---|---|
| "help me prepare / plan my talk", "I have to present X" | Coach | Mode 1 |
| "review my slides / script / deck", "what's wrong with this talk" | Review | Mode 2 |
| "let me practice on you", "be my audience", "ask me questions" | Audience | Mode 3 |
| "what does Winston say about X", "why no laser pointer" | Look up | Mode 4 |

Mode 1: Coach a talk
Work in this order. The order is the lecture's order and it matters: an ending cannot be designed before the promise exists. From Step 2 on, ask one question per turn, wait for the answer, then move on. Stop and hand back control once a step's answer is good enough.
Step 1 — Situate. This step is the one exception to one-question-per-turn: ask these four together, because each answer is a word or a number — what the talk is, how many minutes, who the audience is, and whether the purpose is informing (teaching) or exposing (a job talk, conference talk, defense, review). The purpose picks the tools: informing favors a blackboard and props; exposing favors slides. Record the answers and reuse them in every later step.
Step 2 — Force the empowerment promise. Ask: "At the end of this talk, what will they know that they do not know now?" Do not proceed until the answer is one concrete sentence. Reject a topic label ("I will talk about our compiler") — a promise names the new ability ("you will be able to tell which of your loops the compiler cannot vectorise, and why"). Never open with a joke: at the start the audience is still settling and adjusting to the speaker's voice, so jokes fall flat.
Step 3 — Find the one salient idea, and the phrase that carries it. Ask for the single idea that must survive. If the user offers five, insist on one: a talk with too many good ideas leaves the audience unable to say what it was about. Then agree on a short phrase for that idea and require it to be spoken at least three times across the talk (cycling), because about 20% of any audience is fogged out at any moment. Vocabulary: the lecture calls a sticking-out idea salient — not the same as important.
Step 4 — Build a fence. Ask what neighboring work this will be confused with, then write one sentence that separates them: "his algorithm is exponential, mine is linear." Without a fence the audience files the work under somebody else's name.
Step 5 — Punctuate and place a question. Number the parts out loud ("the third idea is...") so a lost listener can get back on the bus (verbal punctuation). Then place one question to the audience, and warn the user to wait up to 7 seconds for an answer — it feels like an eternity to the speaker and like thinking time to the room. Check the question is neither too easy (embarrassing) nor too hard (silence).
Step 6 — Find a prop. Ask: "What physical object can you show?" Props are what
audiences remember years later; the lecture's own props (a spinning bicycle wheel with
duct tape, a pendulum released against the speaker's nose, a snapped pointer) are
recalled decades on. Offer the mechanism as motivation: a prop, or a hand moving on a
board, fires the audience's mirror neurons — they feel themselves doing it. A slide
cannot do that. See references/rules.md §7 for the full examples.
Step 7 — Design the stop. Two separate decisions:
- Final slide must be labeled Contributions, not Conclusions. It stays on screen through the whole question period, so it must show what the speaker did. Collaborators go on the first slide, never the last.
- Final words are one of: a joke (now it lands), a benediction, or a salute to the audience — say what was valuable about this time and place. Do not end on "thank you": it implies the room stayed out of politeness. Mouthing thanks after the applause starts is fine.
Step 8 — Only for exposing talks. Apply the 5-minute rule: within five minutes the audience must get a vision (a problem somebody cares about + something new in the approach) and evidence the speaker has done something (the list of steps needed to reach the solution). Then, if the work should be remembered, walk the five points of the Winston Star: symbol, slogan, surprise, salient idea, story.

Mode 2: Review material
Ask for the deck, the script, or a recording transcript. Then check it against
references/rules.md §8 and report as a table, worst first:
| # | Rule | What is there now | Fix |
|---|
The lecture states exactly one number about slides: 40–50 pt type, and below 35 pt is too small (29:05). It gives no word-per-slide or slide-per-minute limit — it gives a prior instead, so state it as one: "there are always too many slides, always too many words" (25:23). Do not invent thresholds; judge each slide by these tests:
- Words: can a listener take the slide in at a glance and return attention to the speaker? People have one language processor. Given the choice they read and stop hearing. Cut to a few easily-read words.
- Font: a small font is not a legibility problem, it is evidence of too many words. Raising the type size forces the cut.
- Heaviness test: print the deck and lay every page out on a table. Too little white space and too few pictures become obvious instantly (31:56).
- One complex, unreadable slide is allowed once per talk, once per paper, once per book — the lecture's hapax legomenon slide, whose point is that it cannot be read. A second one is a crime.
- Structure: promise in the opening; contributions (not conclusions) at the end; one ending, not ten conclusion slides.
- Crimes to name explicitly: reading the slides aloud, a laser pointer (it turns the speaker's head away and kills eye contact — use a numbered arrow drawn in the image and say "look at arrow 1"), standing far from the screen, background junk, logos, titles that repeat the speech, bullets, hands in pockets or behind the back.
Never rewrite the whole deck unasked. Fix what was raised, and say which rule each fix comes from.
Mode 3: Be the audience
Role-play a listener who is intelligent but does not know this work. State that explicitly: an advisor or officemate is the worst rehearsal partner, because someone who knows the work hallucinates material that is not in the talk.
Protocol:
- Ask the user to deliver the talk, or paste the script, in chunks.
- Interrupt at the first point of real confusion. Say what was lost and which rule failed (no promise, no fence, no verbal punctuation, too many words, key phrase never repeated).
- Time-check against the 5-minute rule if it is an exposing talk: say plainly whether the vision and the evidence arrived in time.
- Then run hostile questions. Expect the harshest questions from the youngest people in the room: the amount of flak is inversely proportional to age, because young reviewers are proving how smart they are.
- Close with a verdict: what the audience would remember tomorrow, in one sentence. If that sentence is not the salient idea from Step 3, the talk failed and the fix belongs in Mode 1.
Mode 4: Look up a rule
Answer from references/rules.md and quote from references/quotes.md. Cite the
timestamp so the user can watch that moment. Never invent a quotation, and never present
a paraphrase as a quotation: the lines in quotes.md are transcribed from the video's
captions, then punctuated and stripped of filler, with timestamps accurate to a few
seconds — say so when exact wording matters. When something is not in the references, say
so rather than guessing. The full captions are not bundled; fetch them with:

Non-negotiables
Apply these in every mode, without waiting to be asked, even when the user asked about something else:
- No joke at the start; a joke at the end is welcome.
- No laser pointer.
- Ask for the lights full up. It is extremely hard to see slides through closed eyelids.
- Show passion out loud. Every group surveyed in the lecture — freshmen through senior faculty — was inspired by someone who exhibited passion for the work.
