The prompt

Gemini

You are a professional speechwriter specialized in rhetoric and oral communication. Write a complete speech respecting the following parameters:

Context: [describe the event — e.g.: graduation ceremony, corporate conference, wedding, inauguration]
Audience: [describe the audience — e.g.: 200 colleagues, family and friends, investors]
Target duration: [e.g.: 5 minutes, about 750 words]
Tone: [e.g.: inspirational and warm / formal and institutional / humorous and personal]
Key messages: [list 2-3 central ideas the speech must convey]
Speaker: [briefly describe who is speaking — e.g.: CEO for 10 years, best man, professor]

Structure the speech as follows:

  1. Hook: a memorable opening (anecdote, quote, or rhetorical question)
  2. Body: development of key messages with smooth transitions, concrete examples, and at least one figure of speech (anaphora, extended metaphor, or climax)
  3. Emotional climax: a strong moment that crystallizes the central message
  4. Conclusion: a call to action or a striking closing sentence

Add stage directions in square brackets [pause], [look at the audience], [slower tone] to guide delivery. Use short sentences suitable for speaking. Avoid jargon unless the context requires it.

Why it works

This prompt leverages the expert role (professional speechwriter) to activate the model's rhetorical knowledge, while imposing a four-act structure that guarantees dramatic progression. The contextual parameters (audience, tone, duration) constrain the generation to produce an immediately usable result, while the stylistic requirements (figures of speech, stage directions) elevate the quality beyond simple informative text.

Expected result

You get a complete, structured speech ready to be delivered, with a captivating hook, argued development punctuated with rhetorical figures, and a memorable conclusion. The text includes stage directions in brackets and respects the requested duration, with a language register perfectly adapted to your audience.

FAQ

What speech length should I ask Gemini for optimal results?
Gemini handles speeches of 3 to 15 minutes (450 to 2250 words) very well. For short speeches, specify the number of words rather than the duration for more precision. Beyond 15 minutes, it's best to generate the speech in several sections to maintain coherence and quality for each part. Count about 150 words per minute of speech at normal pace.
How can I personalize the generated speech so it doesn't sound artificial?
The key is to provide personal elements in the prompt: lived anecdotes, references shared with the audience, expressions you naturally use. After generation, read the speech aloud and replace any word or phrase you wouldn't use spontaneously. You can also ask Gemini to rewrite passages by giving examples of your way of speaking.
Can Gemini adapt a speech to different formats (wedding, corporate, funeral)?
Yes, Gemini adapts remarkably well to different registers provided you clearly specify the emotional context and conventions of the format. For a eulogy, indicate the desired reflective tone. For a wedding speech, specify the acceptable level of humor. For a corporate presentation, mention the company culture. The more you detail the expected atmosphere, the more appropriate and respectful the result will be.
