Common Mistakes When Giving a Speech in Public (and How to Avoid Them)

By the MisXVPalabras team · Updated September 13, 2026 · 7 min read

Most speeches that "go wrong" at a wedding or quinceañera don't fail because of a lack of love or good intentions, but because of a handful of very common mistakes that, for the most part, are easy to avoid with a bit of preparation. Knowing them in advance is the fastest way to improve any speech, no matter who's writing it.

Mistake 1: making it too long

By far the most frequent mistake. The emotion of the moment makes you want to say everything, but a speech longer than seven or eight minutes starts to lose the room's attention, no matter how interesting the content is. The solution is simple, if uncomfortable: write the full speech, time it out loud, and cut whole content (not just stray words) until you land in the three-to-five-minute range.

Mistake 2: memorizing the text word for word

Memorizing the entire speech seems like the safest option, but it actually raises the risk: if you forget a single line, it's easy to freeze up entirely trying to recall the next exact word. It's safer to memorize the main ideas and a few key lines (the opening and closing, especially), letting the rest be said in your own words in the moment.

Mistake 3: using humor at someone's expense

Jokes about exes, embarrassing secrets shared without consent, or comments that could make a family member present uncomfortable are, without exception, a bigger risk than the payoff of an easy laugh. If you're unsure whether a joke might make someone uncomfortable, the answer is almost always yes, and it's better to replace it with a different idea.

Simple rule: if the joke only works because someone in the room gets exposed or embarrassed, don't use it. Good humor in a speech includes everyone; it doesn't leave anyone out or uncomfortable.

Mistake 4: not practicing out loud before the event

Reading the speech silently creates a false sense that it's "already done." A text can flow perfectly in your head and sound clumsy or too fast when said out loud. Practicing it, ideally in front of another person, at least twice before the event, reveals pacing and length problems that are impossible to catch just by reading.

Mistake 5: not having a clear closing

Many speeches lose steam right at the end, when the speaker isn't quite sure how to finish and keeps adding stray lines after reaching the most emotional moment. Having your exact closing line decided in advance, and saying it with confidence, avoids that "ending that never quite ends" effect.

Mistake 6: not coordinating with other speakers

When several people give speeches at the same event without coordinating, it's common for the same stories or central ideas to be repeated, which takes freshness away from each individual speech. A brief conversation beforehand among those who will be speaking — even just a few days before the event — avoids that repetition and lets each speech add something different to the night.

Mistake 7: ignoring the microphone

A technical but frequent mistake: speaking too far from the microphone, or moving it constantly while talking, which creates volume drops that distract the audience. If you're not familiar with the venue's sound equipment, it's a good idea to test it a few minutes before the event, or at least ask the sound technician how to hold it correctly.

How to review your own speech before the event

A practical way to catch these mistakes in your own text is to read it out loud and ask yourself: does it run under five minutes? does it have one clear central idea? could any joke make someone present uncomfortable? is the closing line exactly defined? If you answer yes to the first three and have the last one clear, your speech is very likely to work well in front of the audience.

Frequently asked questions about common mistakes

Is it a mistake to not use humor at all?

No. A completely sincere speech with no humor can work perfectly well, especially if that's your natural way of expressing yourself. The real mistake isn't the absence of humor, but forcing it when it doesn't fit your style or your relationship with the person being honored.

How bad is it to forget part of the speech in front of the audience?

Much less serious than it feels in the moment. Most guests don't even notice when someone skips a planned part, as long as the speaker continues naturally toward the close instead of stopping to explain the mistake.

Should I apologize if I feel my speech didn't go as planned?

Generally not necessary. Over-apologizing after a speech tends to draw more attention to a supposed mistake than the mistake itself. It's better to finish with confidence and let the love behind the message speak for itself.
