How to pronounce collaborated in American English
kuh·LA·buh·ray·tuhd
Start here
Americans pronounce collaborated as kuh-LA-buh-ray-tuhd (/kəˈlæbəˌreɪɾəd/). In "collaborated", the "t" between vowels sounds like a quick "d" — the tongue briefly taps the ridge behind the upper teeth. This is called the Flap T, and it's why Americans sound more relaxed than the textbook. So instead of kuh·LA·buh·ray·tuht, you get kuh·LA·buh·RAY·tuhd. Stress falls on the second syllable — keep everything else short and quick. You'll hear it in sentences like "He collaborated with researchers from different universities" or "He collaborated with professors from other departments on the project" — more examples below.

uh/ʌ/
Relax your lips, jaw, and tongue completely. Drop your jaw slightly and keep the tongue neutral.
l/l/
Place the tip of your tongue against the alveolar ridge just behind your top front teeth, the same contact point as /t/, /d/, and /n/. The difference is what happens to the air: for /l/, you let it flow continuously around the <em>sides</em> of the tongue (that's why /l/ is called a lateral). Turn your voice on the whole time. Lips stay relaxed, no rounding or flaring. For the Dark L variant at the end of a syllable, also pull the back of the tongue up and back toward the soft palate.
a/æ/
Drop the jaw noticeably. Keep the body of the tongue low and forward, and don't let the back of the tongue raise toward the soft palate. Pull the lip corners back slightly, almost a starting smile.
b/b/
Press your lips together, add vocal cord vibration, then release.
uh/ʌ/
Relax your lips, jaw, and tongue completely. Drop your jaw slightly and keep the tongue neutral.
r/r/
SyllabicThe schwa before R disappears — R becomes the vowel of the syllable. This is the 'er' sound without a distinct vowel before it.
ay/eɪ/
Start with your jaw slightly open and the front of your tongue forward and slightly up. Glide upward, your jaw closes a little more and your tongue arches higher toward the roof of the mouth.
t/t/
FlapQuickly bounce the front of your tongue against the roof of your mouth. Don't stop the airflow — just a quick tap.
uh/ʌ/
Relax your lips, jaw, and tongue completely. Drop your jaw slightly and keep the tongue neutral.

Common pronunciation mistakes in American English.
The textbook way isn't wrong — it's just not how anyone actually says it.
01
Saying a hard "T" in the middle.
In "collaborated", the "t" between vowels sounds like a quick "d" — the tongue briefly taps the ridge behind the upper teeth. /t/ or /d/ becomes a quick tap [ɾ] — sounds like a soft D. The tongue briefly taps the ridge behind the upper teeth.
kuh-LA-buh-ray-tuht→kuh·LA·buh·RAY·tuhd
02
Releasing the final consonant with a puff of air.
In "collaborated", the "d" is not released — the articulators get into position but hold without the burst of air. Air stops but there's no release burst — the articulators hold position.
collaborated→kuh·LA·buh·RAY·tuhd
03
Stressing the wrong syllable.
Stress falls on the second syllable, not the others. Stretch LA — keep everything else short and quick.
KUH·la·BUH·RAY·TUHD→kuh·LA·buh·RAY·tuhd
04
Pronouncing the first syllable too fully.
Don't pronounce the first syllable too fully. The unstressed syllable reduces to a schwa — the lazy "uh" sound — in casual speech.
KUH·LA·buh·ray·tuhd→kuh·LA·buh·RAY·tuhd
Questions
Questions people ask about this.
How is "collaborated" stressed in American English?
Stress falls on the second syllable — say "LA" with a longer, fuller vowel and keep every other syllable short and quick. The respell "kuh-LA-buh-ray-tuhd" marks the stressed syllable in capitals so the rhythm is easy to read at a glance.
Why doesn't the T sound like a T in "collaborated"?
In American English, when /t/ sits between two vowels with the second one unstressed, it turns into a quick D-like flap. So "collaborated" sounds closer to "kuh-LA-buh-ray-tuhd" than to a crisp-T pronunciation. This is the flap-T rule, one of the most distinctive sounds of casual American speech.
Why does the first syllable in "collaborated" reduce to "uh"?
Unstressed syllables in American English collapse toward a schwa — a lazy, neutral "uh" sound. The full vowel is what textbooks teach, but in actual American speech every unstressed vowel reduces. The respell "kuh-LA-buh-ray-tuhd" shows the reduced form so you can hear the casual rhythm directly.
Is the American pronunciation of "collaborated" different from British English?
American English uses different vowel shapes, a relaxed retroflex R, and connected-speech tricks like flap-T and glottal-stop T that British Received Pronunciation generally avoids. The respell "kuh-LA-buh-ray-tuhd" reflects the casual American form; British dictionaries typically print a citation form with crisper consonants and different vowel choices.
