How to Use AI to Write a Speech for a Wedding or Birthday

You’ve been asked to say a few words at a wedding, a big birthday or a retirement do, and now there’s a blank page and a knot in your stomach. Most people aren’t short of love for the person. They’re short of structure, and they worry about rambling, freezing or telling the wrong story in front of Grandma.

An AI chatbot is a surprisingly good speech partner. It won’t know your best friend, so it can’t write the speech for you, but it can interview you, spot the strongest stories, give you a shape that works and help you cut it to time. This guide takes about an hour from blank page to a draft you can rehearse.

What you’ll need

• An AI chatbot such as ChatGPT, Claude, Gemini or Grok (free versions are fine)
• The basics: the occasion, your relationship to the person, the length you’ve been given (usually 3–5 minutes), and who will be in the room
• A handful of real memories, in-jokes, phrases they always say, and anything you must not mention
• A timer on your phone for rehearsing
• About an hour, spread over two or three sittings if you can

Step-by-step: write your speech with AI

1. Set the brief. Tell the AI the occasion, your role (best man, maid of honour, parent, friend, colleague), the tone you want and the time limit. A 3-minute speech is roughly 400–450 spoken words, so say how long you have.
2. Let it interview you. Ask the AI to question you one topic at a time (prompt 1). Answering questions is far easier than writing from scratch, and it pulls out details you’d forget, like the disastrous camping trip or the way they always remember everyone’s birthday.
3. Pick your stories. From your answers, ask the AI which two or three stories best show who the person is. Good stories are short, specific and kind. Inside jokes that only three people will get rarely land with a room of eighty.
4. Build the structure. Ask for an outline: a warm opening, who you are, the stories, a sincere bit about the person (and their partner at a wedding), and a toast. Structure is the part AI does best.
5. Write a first draft together. Ask for a draft in plain, spoken language using only the facts you gave it (prompt 2). Tell it not to invent anecdotes. Then rewrite each paragraph in your own voice. If a line doesn’t sound like something you’d say at the pub, change it.
6. Check the room. Ask the AI to read the speech as different guests would: an elderly relative, the couple’s new in-laws, a child. It’s good at flagging jokes that might embarrass someone or exclude people (prompt 3).
7. Cut it to time. Read it aloud with a timer. If it’s long, ask the AI to trim it by a set number of words without losing the best story. Shorter almost always feels better on the day.
8. Make speaking notes. Ask for a version as short bullet cues on one card, so you can look up and talk rather than read every word.

Copy-paste prompts

1. Interview me for my speech

I'm giving a [WEDDING / 50TH BIRTHDAY / RETIREMENT] speech for [NAME], who is my [RELATIONSHIP]. I have about [NUMBER] minutes and the audience is [WHO WILL BE THERE]. I want the tone to be [WARM AND FUNNY / MOSTLY HEARTFELT].
Interview me to gather material. Ask me one question at a time about memories, their personality, funny moments and what they mean to people. After about 10 questions, summarise the three strongest stories and explain why each would work for this audience.

2. Turn my notes into a draft

Using only the stories and details below, write a speech of about [NUMBER] words that I can read aloud. Use short sentences and natural spoken British English. Structure: opening line, who I am, two or three stories, a sincere section about [NAME], and a toast at the end.
Do not invent any anecdotes, names or facts. Where you need a detail I haven't given, write [ADD DETAIL] instead.
My notes: [PASTE YOUR ANSWERS AND NOTES]

3. Check it for the room

Here is my speech: [PASTE SPEECH]
Read it as these guests would: an elderly relative, a colleague who barely knows [NAME], and [PARTNER'S NAME]'s family. Flag anything that could embarrass someone, exclude people, or reference exes, money or drinking in a way that might go down badly. Suggest gentler alternatives that keep the humour.

4. Trim and make cue cards

My speech below takes about [NUMBER] minutes to read aloud and needs to be [TARGET] minutes. Cut it to about [WORD COUNT] words, keeping the [NAME OF BEST STORY] story and the toast. Then give me a cue-card version: no more than 12 short bullet points I can glance at.
[PASTE SPEECH]

Recommended tools

• ChatGPT: good at interviewing you and turning rough notes into a spoken draft; voice mode lets you rehearse aloud.
• Claude: strong at gentle rewrites and keeping your own phrasing intact.
• Gemini: handy if your notes are in Google Docs and you want help editing there.
• Grok: quick for brainstorming opening lines and toast ideas.
• Your phone’s voice recorder: record a run-through and listen back for the bits where you stumble.

Tips and mistakes to avoid

• Never let AI invent memories. A made-up anecdote will be spotted immediately by people who were there. Use only your own stories.
• Write for the ear, not the eye. Short sentences, one idea each. If you run out of breath reading a sentence, split it.
• Don’t overdo the jokes. One or two good laughs and a sincere moment beat a stand-up set. Ask the AI for gentler versions if in doubt.
• Mention the right people. At a wedding, check whether you’re expected to thank hosts, parents or bridesmaids. Ask the couple rather than guessing.
• Keep private details private. You don’t need to paste full names, addresses or anything sensitive into a chatbot. First names are plenty.
• Rehearse at least three times. Once alone, once to a friend, once with a timer. The words matter less than delivering them calmly.
• Bring a printed copy. Phones die and screens dim. A card in your pocket is reassuring even if you never look at it.

FAQ

Is it cheating to use AI for a wedding speech?

Not if the stories and feelings are yours. Think of AI as a friend who helps you organise your thoughts and tidy your wording. The guests want to hear you, so rewrite anything that doesn’t sound like you.

How long should a wedding or birthday speech be?

Usually three to five minutes, unless you’ve been told otherwise. That’s roughly 400–700 spoken words. Ask the host what they expect and plan to finish a little early.

What if I’m nervous about public speaking?

Practise with your cue cards, pause after the funny lines, and look at one friendly face. You can also ask the AI to role-play a rehearsal, giving you feedback on pacing from a transcript.
