How to pronounce “congestion”
Congestion is pronounced /kənˈdʒestʃən/. It has 3 syllables, and the beat falls on the second one — dʒes. Below: the syllable split, native audio in both accents, the mistake people actually make with this word, and every individual sound in it explained.
Syllables and stress
Split it into 3 beats. The highlighted syllable is the strong one: say it louder, longer and a touch higher in pitch, and let the others fall away. English is a stress-timed language, so getting dʒes in the right place matters more to a listener than getting every vowel perfect.
Stress pattern oOo — capital letters mark the stressed beats.
The common mispronunciation of “congestion”
✗ Often said: /ˈkɑːŋestɪɑːn/ — the spelling, read straight off the page.
✓ Actually: /kənˈdʒestʃən/
Why the two come apart: the stress lands on the second syllable (“dʒes”), not on the first one — putting the beat at the front is the mistake almost everyone makes; also, the unstressed vowels flatten all the way down to /ə/ — English swallows them, so they never sound the way they are written; also, a consonant letter takes an unexpected sound value here, so reading it "as written" comes out wrong.
This is why reading English aloud from spelling alone goes wrong so often: the letters of “congestion” are not a reliable map of its sounds. The IPA is — each symbol stands for exactly one sound, every time.
