I’ll never forget watching a brilliant engineer present a safety protocol to an international team. His content was impeccable and his data was solid, but when he said “We need to focus on hell and safety,” the room went quiet for all the wrong reasons.
He meant “health,” of course. But that one missed sound changed how seriously people took his message.
I work with professionals from across Europe, and I can tell you with absolute certainty that having an accent doesn’t damage your credibility. What damages your credibility is when people can’t understand what you’re saying, or worse, when a mispronounced word changes your meaning entirely.
So let’s talk about the three pronunciation issues that actually matter when you’re presenting in English, and more importantly, what you can do about them.
It’s not about sounding British or American
Before we get into the specifics, I need to say this clearly, the goal isn’t to sound native. That’s an unrealistic and frankly unnecessary goal.
The goal is to be understood, to sound confident and clear and for your audience to focus on your ideas, not struggle to decode your words.
I’ve coached executives from different nationalities and the most successful ones were the ones who’ve learned to articulate clearly and project confidence, accent and all.
Mistake 1: Inconsistent word stress
English is a stress-timed language, which means certain syllables in words carry more weight than others. When you get the stress wrong, even a simple word becomes hard to recognise.
Take the word “present.” As a verb (to present), the stress is on the second syllable: pre-SENT. As a noun (a present), it’s on the first: PRE-sent. Use the wrong stress pattern, and your audience has to work harder to understand you.
This happens all the time with common business words:
- REcord (noun) vs. reCORD (verb)
- PROject (noun) vs. proJECT (verb)
- CONtent (satisfied) vs. conTENT (material)
When you’re presenting, you’re likely using dozens of these words. If the stress is off, your audience needs to make an extra effort to follow along.
What you can do about it:
When you’re preparing your presentation, mark the stressed syllables in any words you’re not 100% certain about. There are excellent online dictionaries that show you exactly where the stress falls.
Better yet, record yourself practising. You’ll hear immediately when a word doesn’t sound quite right. Then look it up, correct it, and practise it again.
The improvement is faster than you think. I had a client who spent just ten minutes a day for two weeks working on word stress. The feedback from his team was immediate: “You sound so much more confident now.”
Mistake 2: Silent letters that aren’t actually silent
English is full of letters that don’t get pronounced. The “k” in “know,” the “b” in “doubt,” the “l” in “salmon.” Native speakers learn these through years of exposure.
But here’s where it gets tricky for non-native speakers: sometimes you skip letters that should be pronounced.
The most common one I see? The final consonant sounds.
Words like “asked,” “fixed,” “helped” all end with a clear consonant sound. But I often hear “ask,” “fix,” “help” instead. It’s subtle, but it matters because those endings carry grammatical meaning. They tell your audience whether you’re talking about the past or the present.
“We fixed the issue yesterday” vs. “We fix the issue yesterday” – one sounds professional, the other sounds like something’s missing (because it is!)
What you can do about it:
Pay special attention to word endings when you’re speaking English. This is especially important in presentations where you need to sound polished.
Practice saying complete words, not abbreviated versions. “Asked” has three sounds at the end: k-s-t. Say them all. It feels unnatural at first, but it becomes automatic quickly.
And here’s a simple tip that never fails: slow down. When you rush, those final consonants disappear. When you give yourself time to finish each word properly, your clarity improves dramatically.
Mistake 3: The sounds that change your meaning entirely
This is the “health vs. hell” problem I mentioned earlier.
Certain English sounds, when mispronounced, create completely different words. And some of those words are… unfortunate in a professional setting.
The “th” sound is the classic example. It doesn’t exist in many languages, so speakers substitute it with “s,” “t,” or “d.”
“Think” becomes “sink” or “tink.” “Thirty” becomes “sirty.” “This” becomes “dis.”
Is it the end of the world? No. Will people usually figure out what you mean from context? Yes. But there are certain words where getting this sound right really matters.
If you’re presenting about a “public” initiative and it sounds like you’re saying something else entirely, that’s a problem. If you’re talking about “health and safety” and people hear something quite different, that undermines your message.
What you can do about it:
The “th” sound requires your tongue to be between your teeth. It feels strange. It looks a bit silly when you’re practising in the mirror. Do it anyway.
Practice with words you use often in your work. If you talk about “growth,” “health,” “method,” or “worth” regularly, those are the ones to focus on.
And here’s what I tell all my clients: you don’t need to perfect every “th” sound in casual conversation. But when you’re presenting? When you’re standing in front of clients or senior leaders? Those key words in your presentation deserve clear, confident pronunciation.
Mark them in your notes. Practice them specifically. It makes a bigger difference than you’d expect.
The one word you should never mumble
There’s one word in every presentation that must be pronounced clearly, and that’s the name of your company.
I’ve seen presenters gloss over their own company name because they’re not confident about how to say it. Or they rush through it. Or they mumble it.
Your company name should be said with pride and clarity. If you’re not sure how to pronounce it properly in English, ask a native speaker. Practise it until it feels natural.
The same goes for key technical terms, product names, or any terminology that’s central to your message. These aren’t words you can afford to stumble over.
This isn’t about perfection
Let me be very clear: I’m not asking you to eliminate your accent or speak like you were born in London or New York.
I’m asking you to be understood. I’m asking you to make sure that when you present in English, your audience focuses on your expertise, your ideas, and your recommendations, not on trying to decode what you just said.
The professionals I work with who’ve made these adjustments don’t sound like different people. They sound like themselves, just clearer. Just more confident.
And that confidence is what your audience notices. Not your accent. Your confidence.
Start with one thing
If you take nothing else from this article, take this: pick one area to work on.
Maybe it’s word stress. Maybe it’s those final consonants. Maybe it’s one specific sound that you know trips you up.
Work on that one thing for two weeks. Record yourself. Listen back. Adjust. Practice.
You’ll be surprised how much clearer you sound when you fix just one consistent issue.
And once that’s automatic, pick the next thing.
Clarity builds confidence. Confidence builds credibility. And credibility is what makes your presentations land.
