How to Use Claude as a Speechwriter: Toasts, Wedding Speeches and Business Talks

10 Min. Lesezeit KissMySkills

Claude is useful for speeches in three places: finding the single story worth telling, cutting a draft to fit a slot, and marking the text up so you know where to breathe. It is weak at the one thing that makes a speech land, which is sounding like you. Its default is a polished essay that you would never say out loud. Work in four passes (intake, structure, draft, read-aloud revision), give it three to five sentences you have really spoken, and hand it a word budget instead of a minute count, because it cannot hear you talk.

What do you give it before it writes a word?

Ask for "a funny speech for my brother's wedding" and you get remarks anyone could give at any wedding. Four inputs are ones Claude cannot guess:

The room. Who is listening and who should not be embarrassed. Dana's room includes grandparents who do not know the story of the borrowed car.

The slot. The minutes you have been given, and whether there is a microphone or just a raised glass.

One true story. A real moment with a place and a name in it. Claude can shape a story, but it cannot remember one, and if you do not supply it, it will make one up.

Your voice. Three to five sentences you have actually said out loud: from a voice note, a text message you wrote in a hurry, a toast you gave once. These beat any adjective: "warm but funny" tells it nothing, while your own sentences show how long you let a thought run.

Start with an intake step so the draft is not built on assumptions:

You are my speechwriter. Do not write the speech yet. Interview me first. Occasion: [WEDDING TOAST FOR MY BROTHER] Slot: [3.5 MINUTES, STANDING WITH A GLASS, NO SLIDES] Audience: [90 GUESTS, BOTH SETS OF GRANDPARENTS, MIX OF FRIENDS AND COLLEAGUES] What the room should feel when I sit down: [LAUGHED, THEN A LUMP IN THE THROAT] Here are sentences I have really said (do not improve them): 1. [PASTE REAL SENTENCE] 2. [PASTE REAL SENTENCE] 3. [PASTE REAL SENTENCE] Ask me no more than 6 questions, numbered, one line each. Cover: the one story I want to tell, a detail only I would know (a place, a name, an object), anything I must NOT mention, who must be thanked, how I pronounce any hard names, and whether I am comfortable with laughter or want it dry. After my answers, summarise my voice in 5 bullets (sentence length, humour style, words I use, words I never use) and wait for my OK.

The cap on questions matters; without it Claude asks fifteen. The voice summary is the checkpoint: if it says "formal, eloquent", your samples were too clean, so paste a messier one.

How do you make a speech fit a ten-minute slot, or a three-minute one?

Do not tell Claude "make it three minutes". It has no clock and no mouth, and its estimate will drift by a minute or more. Measure yourself instead: read any 200 words of your own writing aloud, standing, at the pace you will use on the day, and time it. Divide to get your words per minute. Your number is the only one that counts, and a toast with pauses and laughter runs slower than a read-through. The AI Speech Generator below plans at 110 and 130 words per minute.

Then give Claude a word budget with two cut points:

Write to a budget, not to a duration. My measured pace: [120] words per minute reading aloud. Slot: [3.5] minutes. Subtract [30] seconds for laughter and pauses. So the spoken word budget is [___] words, hard maximum [___]. Rules: - Count the words in your draft and state the count at the end. - Mark two optional cuts, each removable without breaking the speech, with their word counts. If the best man runs long, I drop Cut A. If the toasts before me overrun, I drop both. - If you cannot hit the budget without losing the story, tell me which part to sacrifice instead of squeezing every sentence.

Two marked cuts beat any amount of trimming, because events run late and you will not rewrite on your feet. Check the word count yourself in a document.

How is a toast built differently from a keynote?

The same four paragraphs do not work for every occasion, and this is where a general chat tends to flatten everything into "opening, three points, closing".

A toast is one story and one turn: open on the image, tell the story with names and a place, turn it in one sentence toward the couple, then lift the glass. A wedding speech can carry more feeling but still only one thread. A business talk is built the other way round: the point first, because colleagues are checking their phones, then two or three proofs, then a call to act. A eulogy needs a plain voice and permission to go slowly.

Ask Claude to propose a structure and defend it before it writes prose:

Propose the structure for my [WEDDING TOAST] before drafting. Give me: (1) the through-line in one sentence, (2) a beat list with a word budget per beat, (3) where the single laugh line goes and where the quiet line goes, (4) the exact last line, kept under 10 words, ending on the couple and not on me. Use my story: [DESCRIBE IT IN 3-4 SENTENCES, INCLUDING THE PLACE AND THE NAME]. Do not add any fact, quote, date or memory that is not in my notes. If a gap needs a detail, write [ASK ME] in its place.

The [ASK ME] instruction is how you stop invented memories. Without it, Claude will cheerfully supply that you "once drove six hours to a lake" because it makes a good beat.

How do you stop it sounding like a greeting card?

Ban the phrases by name. Claude's speech register is built from ceremonial writing: "we are gathered here today", "love is not just a feeling, it is a choice", a famous quote in the second paragraph. Tell it to avoid those, and require short sentences that survive a single breath.

Finish with the pass that matters most, the read-aloud revision. Draft, then paste it back:

Here is the draft. Act as a speech editor, not a rewriter. [PASTE DRAFT] 1. Flag every sentence that cannot be said in one breath at a slow speaking pace. Split it, using only my words where possible. 2. Flag every place where a listener who zoned out for 5 seconds would be lost. Add a short repeated phrase there (a callback to my opening line). 3. Flag any word I would stumble on out loud: tongue-twisters, three consonants in a row, names. Offer a plainer one. 4. Delete anything that sounds like a greeting card or a quotation website. List what you deleted. 5. Mark delivery: / for a short pause, // for a long pause, CAPS for the one word to lean on, [SLOW] where I must slow down, [LOOK UP] at the line to say to the couple. Do not tell me the speech is moving. Tell me what is loose.

Run the result aloud yourself, standing up, with a timer, and edit by hand. That step cannot be delegated.

Tom taught me to drive. // In a car park. / In the rain. / In a car that was NOT his. [SLOW] He stalled it eleven times. / He never raised his voice once. // [LOOK UP] Anna, / that is the man you are marrying. // Patient / when it makes no sense to be. / Glasses up. // Word count: 48 spoken / about 24 seconds at 120 wpm (illustration, not a measurement)

Where does Claude fail at this?

It invents the anecdote. Ask for "a personal story" and it writes one, with a lake, a sibling and a lesson, and you end up reading out a memory that never happened. Feed it real material only.

It cannot tell whether a joke works in a room. A joke about the in-laws that looks safe on the page can land very differently with the grandparents present. Have one honest person hear the speech first.

It writes for the eye. A sentence with two subordinate clauses reads well and leaves you out of breath at the second comma. That is why the read-aloud pass exists.

It smooths out your voice. If you speak in fragments and dry understatement, the draft drifts toward balanced, slightly grand prose. Re-paste your three real sentences whenever it feels like someone else's.

It cannot know what the room knows: that a topic is raw this year, that two guests are not speaking. These are your calls.

Its timing is a guess until you read the text aloud with a timer.

It over-quotes. A famous line from a poem or film in your closing is a cliche within seconds. If a quotation helps, you choose it and check the source.

For a eulogy, use Claude for structure and trimming only, and keep the memories and the wording yours.

Frequently asked questions

Is there a Claude skill for speechwriting?

Yes. Cosgrove - Speechwriter AI Skill ($19) interviews you for your real voice, proposes a structure for the occasion, writes a draft to your time slot and returns delivery notes with pauses and emphasis. For a quicker, cheaper route, the AI Speech Generator ($5) is a prompt that returns a marked-up speech with a word count and two cuts.

Can Claude write a wedding toast or best man speech?

It can draft and tighten one, but the story has to be yours. Give it one true anecdote with names and a place, three real sentences you have said, and a word budget. It will shape the structure and mark the pauses. It will invent a memory if you ask for a story without supplying one, so tell it to put [ASK ME] wherever a detail is missing.

How do I make Claude write a speech of an exact length?

Do not ask for minutes. Time yourself reading 200 words aloud to get your words per minute, then give Claude a word budget and ask for two optional cuts. Count the words yourself in a document and read the final text aloud with a timer, because Claude cannot hear your pace.

What is Claude bad at when writing speeches?

It invents anecdotes, cannot judge whether a joke works with a specific audience, writes sentences that look good but are hard to say in one breath, and pulls your voice toward generic ceremonial language. Re-paste your own spoken sentences, run a read-aloud revision pass and have one honest person hear it before the day.

Can I use Claude for a eulogy?

Use it for structure, trimming and a read-aloud check, not for the memories or the wording. Keep the draft short and plain, include only what you know to be true, and have a trusted person read it first. This guide is writing help, not a substitute for the support you may need around a loss.
