Picture this: your team lead says, “Can you walk us through your solution in the all-hands meeting tomorrow?” Your heart rate spikes. You know the code cold — but presenting it in English, in front of 30 people, feels like a completely different skill. For many Vietnamese developers, public speaking in English triggers a unique cocktail of fears: What if I mispronounce something? What if they don’t understand my accent? What if I blank out mid-sentence? These feelings are real, they’re common, and — with the right practice — they’re absolutely manageable.
🗣️ Key Phrases to Say Out Loud
Master these eight phrases. They work as anchors when your mind goes blank and signal to your audience that you’re in control.
1. “Let me take a moment to gather my thoughts.” /lɛt miː teɪk ə ˈməʊmənt tə ˈɡæðər maɪ θɔːts/ Để tôi suy nghĩ một chút. Use this when a question catches you off guard. It’s professional, not weak — it shows you think before you speak.
2. “I’d like to walk you through…” /aɪd laɪk tə wɔːk juː θruː/ Tôi muốn hướng dẫn bạn qua… Your go-to opener when presenting a system, diagram, or feature. “I’d like to walk you through our deployment pipeline.”
3. “To put it simply…” /tə pʊt ɪt ˈsɪmplɪ/ Nói một cách đơn giản… Bridges complex technical ideas to non-technical stakeholders. Use it when you’re about to give the 30-second version of something deep.
4. “Can everyone hear me okay?” /kæn ˈɛvrɪwʌn hɪər miː ˌoʊˈkeɪ/ Mọi người nghe tôi rõ chứ? Always open a remote presentation or large-room talk with this. It gives you two seconds to settle your nerves while the audience adjusts.
5. “I’ll take questions at the end.” /aɪl teɪk ˈkwɛstʃənz æt ðə ɛnd/ Tôi sẽ trả lời câu hỏi vào cuối buổi. Sets expectations and protects your flow. Say this right after your opening so people know the structure.
6. “That’s a great question — let me think about that.” /ðæts ə ɡreɪt ˈkwɛstʃən — lɛt miː θɪŋk əˈbaʊt ðæt/ Câu hỏi hay đấy — để tôi nghĩ xem. Buys you 3–5 seconds of thinking time without sounding lost. Use it honestly, not reflexively for every question.
7. “To summarize what we’ve covered…” /tə ˈsʌməraɪz wɒt wiːv ˈkʌvəd/ Tóm tắt lại những gì chúng ta đã đề cập… Your closing signal. Audiences pay more attention at the end — use this phrase to land your key points one more time.
8. “Does that make sense to everyone?” /dʌz ðæt meɪk sɛns tə ˈɛvrɪwʌn/ Mọi người có hiểu không? Invites engagement without putting anyone on the spot. Better than silence after a complex explanation.
📚 Vocabulary
Confident /ˈkɒnfɪdənt/ — tự tin “She gave a confident demo of the new API endpoints, handling every question without hesitation.”
Articulate /ɑːˈtɪkjʊlɪt/ — diễn đạt rõ ràng, mạch lạc “Being articulate about trade-offs is what separates a senior developer’s presentation from a junior one’s.”
Audience /ˈɔːdɪəns/ — khán giả, người nghe “Know your audience — a room full of engineers needs different framing than a product review with executives.”
Clarity /ˈklærɪti/ — sự rõ ràng “The architecture diagram lacked clarity, so he redrew it with cleaner labels before the presentation.”
Pace /peɪs/ — tốc độ (nói) “Slow your pace when explaining the core concept — rushing is the most common mistake in tech presentations.”
Enunciate /ɪˈnʌnsɪeɪt/ — phát âm rõ từng âm tiết “In a large meeting room, enunciate clearly — the back row needs to hear every word of your demo.”

Script: 90-Second Tech Feature Demo
Read this aloud — record yourself if you can:
“Good morning everyone. Can everyone hear me okay?
I’ll take questions at the end.Today I’d like to walk you through the new rate-limiting feature we shipped this sprint.
To put it simply: before this change, a single client could flood our API and slow it down for everyone. Now, each client gets a quota — 1,000 requests per minute — and if they exceed it, they get a 429 error instead of degrading our service.
The implementation uses a Redis sliding window counter. I chose this approach because it’s accurate under burst traffic and adds less than 2 milliseconds of latency per request.
To summarize what we’ve covered: we now have fair usage enforcement, the system is more resilient under load, and the rollout is behind a feature flag so we can disable it instantly if needed.
Does that make sense to everyone? I’m happy to go deeper on the Redis implementation if useful.”
Role-Play: Handling a Tough Question
Interviewer: “What happens to queued requests when Redis goes down?”
Your response:
“That’s a great question — let me think about that. Honestly, I don’t know the exact failover behavior off the top of my head. My assumption is we’d fall back to an in-memory counter, but I’d want to verify that in the code before giving you a definitive answer. Can I follow up with you after the meeting?”
This response is honest, professional, and shows engineering maturity. Never bluff — your audience will respect “I’ll verify and get back to you” far more than a confident wrong answer.
⏱️ 5-Minute Speaking Drill
Run this drill every morning this week.
Step 1 — Warm-up (30s) Loosen your jaw: open your mouth wide, move it side to side, then say “ma-me-mi-mo-mu” three times at normal speed, then fast.
Step 2 — Shadow this sentence 3x (30s) “I’d like to walk you through the deployment pipeline we built last sprint.” Match the rhythm. Stress “walk,” “through,” and “pipeline.”
Step 3 — Tongue twister 3x (30s) “Six slick slim slippery slides.” Go slow first, then faster. Clarity beats speed.
Step 4 — Record the demo script (2 min) Use your phone. Read the 90-second script above. Don’t stop for mistakes — keep going, just like a real presentation.
Step 5 — Review: did you sound confident? (1 min) Play it back. Ask yourself:
- Did I rush through the technical parts?
- Did I pause naturally at commas and periods?
- Was my pace slower than I expected? (Usually a good sign.)
🏆 Weekend Challenge
Find one opportunity this weekend to speak English out loud to a real person — or record yourself for 2 minutes on any tech topic you know well. Upload it to a private YouTube link and watch it once without cringing. The goal isn’t perfection. The goal is getting comfortable hearing your own voice in English. That discomfort is exactly where confidence gets built.
Public speaking is a skill, not a talent. Every confident presenter you admire was once the developer sweating through their first demo. The difference is repetition.
Start the timer.
