If you have ever frozen mid-sentence because you were not sure how to pronounce “repository” or “deprecated”, this article is for you. Today’s session is pure speaking practice — no theory, just drills you can do out loud right now.
Why Shadowing Works
Shadowing means listening to a sentence and repeating it immediately, matching the speaker’s rhythm, stress, and intonation. It is how actors learn accents and how polyglots build fluency fast. For developers, the challenge is not just general English — it is the specific vocabulary of our field. Words like cache, queue, and schema trip up even fluent speakers because they look nothing like they sound.
This session targets the sounds that Vietnamese speakers find hardest: the th sound, short vowels, and final consonants that Vietnamese often drops.
🗣️ Key Phrases to Say Out Loud
Practice these phrases until they feel automatic. Say each one 5 times, slowly first, then at normal speed.
-
“I’ll push the fix to the branch shortly.” /aɪl pʊʃ ðə fɪks tə ðə bræntʃ ˈʃɔːrtli/ — Note: the before consonant = /ðə/, the before vowel = /ðiː/
-
“This function is deprecated — use the new API instead.” /ðɪs ˈfʌŋkʃən ɪz ˈdeprəkeɪtɪd/ — deprecated stress: DE-preh-KAY-ted
-
“We need to refactor this — the tech debt is piling up.” /wiː niːd tə ˈriːfæktər ðɪs/ — Final t in debt is silent: /det/
-
“Can you walk me through the architecture diagram?” /ˈɑːrkɪtektʃər ˈdaɪəɡræm/ — architecture: AR-ki-tek-cher (4 syllables)
-
“The cache is stale — we should invalidate it.” /ðə kæʃ ɪz steɪl/ — cache rhymes with cash, NOT cah-shay
-
“Let me merge your PR after the review.” /let miː mɜːrdʒ jɔːr piː ɑːr ˈæftər ðə rɪˈvjuː/
-
“I think there’s a race condition in this thread.” /ðɛərz ə reɪs kənˈdɪʃən ɪn ðɪs θred/ — thread: the th is voiced here — tip of tongue touches upper teeth
📚 Vocabulary
| Word | IPA | Meaning | Example |
|---|---|---|---|
| deprecated | /ˈdeprəkeɪtɪd/ | outdated, scheduled for removal | ”This method is deprecated in version 3.” |
| throttle | /ˈθrɒtl/ | limit rate of something | ”We throttle API calls to 100 per minute.” |
| schema | /ˈskiːmə/ | structure/blueprint of data | ”Update the database schema first.” |
| queue | /kjuː/ | line of items to be processed | ”The job queue is backed up.” |
| verbose | /vɜːrˈboʊs/ | producing too much output/detail | ”Turn off verbose logging in production.” |
| latency | /ˈleɪtənsi/ | delay in response time | ”High latency is killing the UX.” |
| rollback | /ˈroʊlbæk/ | revert to previous state | ”We had to rollback the deployment.” |
🔤 Tech-Themed Tongue Twisters
Read each line slowly, then speed up. Focus on clear articulation, not speed.
For the TH sound (/θ/ — voiceless, like “think”):
“The thread threw a thousand throttled throughput tests.”
For short vowels (ɪ vs iː):
“This ship’s script is shipped — it is distinct, isn’t it?”
For final consonants (Vietnamese often drops these!):
“Fixed bugs, test passed, git pushed, branch merged.” — Make sure every final consonant is clear: fi-X-T, te-S-T, pu-SH-T
For V vs W:
“The web server verifies every value in the view.” — Vietnamese /v/ is fine here, but make sure /w/ in “web” and “view” is a lip-rounding sound
🎯 Practice Now
Dialogue: Code Review Feedback
Read both roles out loud. Then record yourself as DEV and play back to check clarity.
LEAD: “I left some comments on your PR. The logic looks solid, but there are a few things I’d like you to address.”
DEV: “Sure, I saw the comments. The main concern is the database query inside the loop, right?”
LEAD: “Exactly. It’s causing N+1 queries. Can you move it outside and batch the calls?”
DEV: “Got it. I’ll refactor that part and push an update this afternoon.”
LEAD: “Great. Also, add a unit test for the edge case where the list is empty.”
DEV: “Will do. Should I request another review once I push, or are you okay to merge after that?”
LEAD: “Just ping me on Slack when it’s ready. I’ll take a quick look.”
⏱️ 5-Minute Drill
Do this drill out loud. Set a timer for 5 minutes.
Minute 1 — Warm up: Say the 7 key phrases above, once each, slowly and clearly.
Minute 2 — Tongue twisters: Go through all 4 tongue twisters, twice each.
Minute 3 — Vocabulary drill: For each word in the vocabulary table, say: the word → the IPA → the example sentence. Do not read — look at the word and recall.
Minute 4 — Dialogue shadow: Read the dialogue above out loud, playing both roles. Focus on final consonants.
Minute 5 — Free speak: Answer this question out loud for 60 seconds: “Describe the last bug you fixed — what was it, how did you find it, and what was the fix?”
No notes. No preparation. Just talk. If you pause or stumble, keep going. The goal is fluency, not perfection.
One Thing to Do Today
Pick one phrase from the Key Phrases section and use it in a real conversation — a Slack message, a code review comment read aloud, or a standup. Conscious practice in real contexts is what moves vocabulary from “I recognize it” to “I use it automatically.”
You already know the concepts. The English is just the packaging. Practice enough and the packaging becomes invisible — and your ideas come through clearly.
