Let me tell you about the time I said “cash” in a meeting when I meant “cache.” The client looked confused. I said it again, louder: “We need to clear the CASH.” They thought I was talking about payments. It took two minutes of awkward back-and-forth before someone said, “Oh, you mean the cache!” (pronounced “kash” — yes, but with that subtle vowel difference that my Vietnamese mouth just couldn’t produce).
This is Part 2 of my English for Tech Leads series. Today we fix pronunciation — not by making you sound American, but by making you understood.
The Truth About Accents
Let me be clear: you do not need to eliminate your accent. Many of the most successful tech leaders in the world speak English with strong accents — Indian, Chinese, German, French. The goal is intelligibility, not accent elimination.
What matters:
- People understand you on the first try (no repeating)
- Your pronunciation doesn’t distract from your message
- You can say key technical terms correctly
- Your rhythm and stress patterns are close enough to English norms
What doesn’t matter:
- Sounding “native”
- Perfect vowel sounds
- Hiding where you’re from
The 50 Most Mispronounced Tech Words
I’ve compiled this list from years of cringing at my own mistakes and hearing the same errors from Vietnamese and Asian colleagues. Learn these, and you’ll cover 80% of the pronunciation problems in tech meetings.

Vietnamese-Specific Pronunciation Traps
As Vietnamese speakers, we have specific sound challenges that other nationalities don’t:
1. The “th” Sound Problem
Vietnamese doesn’t have the English “th” sounds (θ and ð). We tend to substitute “t” or “d”:
- “think” becomes “tink” → Practice: stick your tongue between your teeth
- “this” becomes “dis” → Practice: the tongue barely touches the top teeth
- “three” becomes “tree” → Huge difference in meaning!
- “method” → the “th” is softer here, almost a “t” — that’s okay
Daily drill: Say these 5 times fast: “this thing thinks three thoughts through”
2. Final Consonants
Vietnamese words end in vowels or limited consonants. In English, final consonants are crucial:
- “walked” — don’t drop the “t” at the end
- “tasks” — all three final consonants matter: /tæsks/
- “months” — the “nths” cluster is genuinely hard. Simplify to “munts” if needed — better than “mon”
- “fixed” → needs the final “st” sound
Daily drill: Practice word pairs: “walk/walked”, “fix/fixed”, “test/tests”, “build/builds”
3. The R/L Confusion
This is the stereotypical Asian pronunciation challenge, and yes, it affects us too:
- “release” vs “rerease” — keep the “l” soft, tip of tongue behind top teeth
- “reliability” — four syllables, the “l” and the “r” are different motions
- “load balancer” — two “l” sounds, practice them
Daily drill: “Really reliable load balancers rarely release wrong results”
4. Word Stress Patterns
Vietnamese is a tonal language with level stress across syllables. English has strong stress patterns that carry meaning:
- DEV-elop-er (not dev-EL-oper)
- ar-chi-TECT-ure (not ar-CHI-tect-ure)
- AN-a-lyze (not an-A-lyze)
- com-MU-ni-cate (not com-mu-NI-cate)
The rule: If you stress the wrong syllable, native speakers often can’t understand you at all, even if every individual sound is correct.
5. Connected Speech
In natural English, words blend together. Vietnamese speakers tend to pronounce each word separately:
- “What do you think?” → native speakers say “Whaddya think?”
- “Going to” → “gonna”
- “Want to” → “wanna”
- “Should have” → “shoulda”
You don’t need to use contracted speech, but you need to understand it when clients use it.
The Shadowing Technique
Shadowing is the single most effective pronunciation practice method. Here’s how:
What is Shadowing?
You listen to a native speaker and repeat what they say in real-time, trying to match their:
- Rhythm (which syllables are long, which are short)
- Intonation (pitch goes up for questions, down for statements)
- Speed (don’t slow down — match their pace)
- Stress (emphasize the same words they emphasize)
How to Practice (10 Minutes)
-
Choose your material (2 min to find it):
- Tech conference talks on YouTube (I recommend: Fireship, Theo, ThePrimeagen)
- TED talks about technology
- Podcast: Syntax.fm, Software Engineering Daily
-
First listen (2 min): Listen to a 30-second clip without speaking. Note the rhythm.
-
Shadow (4 min): Play the same clip and speak along. Don’t worry about understanding — focus on sound.
-
Record and compare (2 min): Record yourself saying the same lines. Listen back. Notice the differences.
Best YouTube Channels for Shadowing
| Channel | Accent | Speed | Best For |
|---|---|---|---|
| Fireship | American | Fast | Short tech explanations |
| ThePrimeagen | American | Natural | Casual tech discussion |
| Computerphile | British | Moderate | Technical deep-dives |
| TED | Various | Measured | Presentation style |
| Google I/O | Various | Professional | Conference format |

Your 10-Minute Daily Pronunciation Drill
Here’s your exact daily routine:
| Time | Activity | How |
|---|---|---|
| 0:00 – 2:00 | Word drill | Say 5 words from the list above. Look up pronunciation on Forvo if unsure. |
| 2:00 – 4:00 | Tongue twisters | Pick one Vietnamese-problem tongue twister (see below). Repeat 5x. |
| 4:00 – 8:00 | Shadowing | Play a 30-second tech YouTube clip. Shadow it 3 times. |
| 8:00 – 10:00 | Record & Review | Record yourself explaining one sentence about today’s work. Listen back. |
Tongue Twisters for Vietnamese Speakers
Practice these daily — they target our specific weak sounds:
- Th sounds: “The thirty-three thieves thought that they thrilled the throne throughout Thursday”
- R/L sounds: “Red lorry, yellow lorry, red lorry, yellow lorry”
- Final consonants: “She sells six thick silk sheets”
- Word stress: “The developer determined the architecture’s reliability”
- Connected speech: “What do you want to do about the deployment?”
The “Good Enough” Standard
Here’s a framework for deciding which pronunciation errors to fix first:
Fix Immediately (Causes Confusion)
- Wrong word stress (people genuinely can’t understand you)
- Missing final consonants (changes meaning: “walk” vs “walked”)
- The th/t substitution when it changes meaning (“three” vs “tree”)
Fix Gradually (Sounds Non-Native But Understood)
- Vowel quality differences (your “a” sounds slightly different — that’s fine)
- R/L confusion in most contexts (context makes meaning clear)
- Intonation patterns (takes years to fully master)
Don’t Worry About (Accent Markers)
- Your accent on vowels that don’t cause confusion
- The exact way you say “er” at the end of words
- Perfect connected speech
Action Items for This Week
- Learn 10 words from the list above — focus on the ones you use most often
- Do the 10-minute drill every morning before work
- Record yourself explaining a technical concept and listen back
- Download Elsa Speak and do one 5-minute session
- Find one YouTube channel for shadowing that you enjoy
The goal is progress, not perfection. If you fix just 2-3 pronunciation errors per week, in two months you’ll sound noticeably more professional. Your clients won’t be able to pinpoint what changed — they’ll just understand you better.
