How to pronounce documentary in American English
dah·kyuh·MEHN·tuh·ree
Start here
Americans pronounce documentary as dah-kyuh-MEHN-tuh-ree (/ˌdɑkjəˈmɛntəri/). In "documentary", the "t" right after N is dropped — the tongue skips the T stop and moves directly from the N position to the next sound. This is called the Silent T after N, the kind of sound shift that makes everyday speech feel effortless. It comes out as DAH·kyuh·MEHN·tuh·ree. Stress falls on the third syllable — keep everything else short and quick. You'll hear it in sentences like "We watched a documentary on television last night" or "The documentary provided a fascinating insight into the artist's life" — more examples below.

ah/ɑ/
Relax your lips and drop your jaw significantly. The tongue tip lightly touches behind the bottom front teeth and the back part of the tongue presses down a little to create more dark space in the back of the mouth.
k/k/
Raise the back of your tongue to touch the soft palate (velum). Stop the air, then release.
y/j/
Lift the middle of your tongue toward the roof of your mouth, but stop just short of touching. /j/ is an approximant, not a stop. The tongue tip stays down, lightly resting near the back of your bottom front teeth. Voice runs through the whole gesture, and the tongue glides smoothly down into the next vowel. The lips stay neutral or pre-shape for the upcoming vowel (rounding early for OO in <em>youth</em>, for example).
uh/ʌ/
Relax your lips, jaw, and tongue completely. Drop your jaw slightly and keep the tongue neutral.
m/m/
SyllabicThe schwa before M disappears — M becomes the vowel of the syllable. Go straight from the previous consonant to M.
eh/ɛ/
Drop your jaw moderately. Touch the tongue tip behind the bottom front teeth and lift the mid-front part slightly toward the roof.
n/n/
Touch the tip or front edge of your tongue to the roof of your mouth behind your teeth. Air flows through your nose.
t/t/
DroppedThe T is skipped entirely. Your tongue doesn't make contact at the T position.
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.
ee/i/
Pull the corners of your lips back slightly. Arch the middle-front of your tongue high toward the roof of the mouth.

Common pronunciation mistakes in American English.
The textbook way isn't wrong — it's just not how anyone actually says it.
01
Pronouncing the silent T after N.
In "documentary", the "t" right after N is dropped — the tongue skips the T stop and moves directly from the N position to the next sound. /t/ is completely silent — the tongue skips the T stop and moves directly from the N position to the next sound.
documentary→DAH·kyuh·MEHN·tuh·ree
02
Stressing the wrong syllable.
Stress falls on the third syllable, not the others. Stretch MEHN — keep everything else short and quick.
DAH·KYUH·mehn·TUH·REE→DAH·kyuh·MEHN·tuh·ree
03
Pronouncing the unstressed 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.
dah·KYUH·MEHN·tuh·ree→DAH·kyuh·MEHN·tuh·ree
Questions
Questions people ask about this.
How is "documentary" stressed in American English?
Stress falls on the third syllable — say "MEHN" with a longer, fuller vowel and keep every other syllable short and quick. The respell "dah-kyuh-MEHN-tuh-ree" marks the stressed syllable in capitals so the rhythm is easy to read at a glance.
Why does the second syllable in "documentary" 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 "dah-kyuh-MEHN-tuh-ree" shows the reduced form so you can hear the casual rhythm directly.
Is the American pronunciation of "documentary" 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 "dah-kyuh-MEHN-tuh-ree" reflects the casual American form; British dictionaries typically print a citation form with crisper consonants and different vowel choices.
