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.
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.
uh/ʌ/
Relax your lips, jaw, and tongue completely. Drop your jaw slightly and keep the tongue neutral.
k/k/
Raise the back of your tongue to touch the soft palate (velum). Stop the air, then release.
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.
p/p/
Press your lips together to stop the air, then release. No vocal cord vibration.
t/t/
Touch the tip or front edge of your tongue to the roof of your mouth just behind your teeth. Keep your jaw relaxed. Stop the air, then release with a puff.
er/ər/
Relax your mouth and lift the tongue back and up. Keep the lips neutral.

Common pronunciation mistakes in American English.
The textbook way isn't wrong — it's just not how anyone actually says it.
01
Releasing the final consonant with a puff of air.
In "helicopter", the "t" 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.
helicopter→HEH·luh·KAHP·ter
02
Stressing the wrong syllable.
Stress falls on the first syllable, not the others. Stretch HEH — keep everything else short and quick.
heh·LUH·KAHP·TER→HEH·luh·KAHP·ter
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.
HEH·LUH·kahp·ter→HEH·luh·KAHP·ter
04
Pronouncing the "R" too clearly.
Americans use a relaxed retroflex R — the tongue curls back rather than rolling. The R is one continuous sound with the vowel before it, not two separate sounds.
… (no R)→… r (curl the tongue)
Questions
Questions people ask about this.
How is "helicopter" stressed in American English?
Stress falls on the first syllable — say "HEH" with a longer, fuller vowel and keep every other syllable short and quick. The respell "HEH-luh-kahp-ter" marks the stressed syllable in capitals so the rhythm is easy to read at a glance.
Why does the second syllable in "helicopter" 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 "HEH-luh-kahp-ter" shows the reduced form so you can hear the casual rhythm directly.
How do I pronounce the R in "helicopter"?
Americans use a relaxed retroflex R: the tongue curls back rather than rolling, and the R is one continuous sound with the vowel before it — not two separate sounds. Don't try to pronounce a separate vowel followed by a separate R. Treat them as a single shape.
Is the American pronunciation of "helicopter" 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 "HEH-luh-kahp-ter" reflects the casual American form; British dictionaries typically print a citation form with crisper consonants and different vowel choices.
