Americans pronounce constantly as KAHN-stuhnt-lee (/ˈkɑnstəntli/). In "constantly", the "t" is squeezed between other consonants and drops out — the surrounding consonants flow together without it — most natural in flowing, casual speech; in careful or formal speech, the T may be lightly present. This is called the Silent T in Clusters, and it's one of the defining features of casual American English. It comes out as KAHN·stuhnt·lee. Stress falls on the first syllable — keep everything else short and quick. You'll hear it in sentences like "The sand dunes shift constantly with the wind" or "The universe is constantly expanding at an accelerating rate" — more examples below.

k/k/

Raise the back of your tongue to touch the soft palate (velum). Stop the air, then release.

Mouth position for /k/ as in KEY
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.

Mouth position for FATHER Vowel
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.

Mouth position for /n/ as in NET
s/s/

Place your tongue tip near the roof of your mouth behind your top teeth. Push air through the narrow gap. No voicing.

Mouth position for /s/ as in SUN
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.

Mouth position for /t/ as in TEN
uh/ʌ/

Relax your lips, jaw, and tongue completely. Drop your jaw slightly and keep the tongue neutral.

n/n/
Syllabic

The schwa before N disappears — N becomes the vowel of the syllable. Go straight from the previous consonant to N.

Mouth position for /n/ as in NET
t/t/
Dropped

The T is skipped entirely. Your tongue doesn't make contact at the T position.

Mouth position for /t/ as in TEN
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.

Mouth position for /l/ as in LET
ee/i/

Pull the corners of your lips back slightly. Arch the middle-front of your tongue high toward the roof of the mouth.

Questions

Questions people ask about this.

How is "constantly" stressed in American English?
Stress falls on the first syllable — say "KAHN" with a longer, fuller vowel and keep every other syllable short and quick. The respell "KAHN-stuhnt-lee" marks the stressed syllable in capitals so the rhythm is easy to read at a glance.
Why does the second syllable in "constantly" 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 "KAHN-stuhnt-lee" shows the reduced form so you can hear the casual rhythm directly.
Is the American pronunciation of "constantly" 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 "KAHN-stuhnt-lee" reflects the casual American form; British dictionaries typically print a citation form with crisper consonants and different vowel choices.
