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.

Mouth position for /l/ as in LET
ar/ɑr/

Open wide for the 'ah' vowel. Lift the tongue back and up while flaring the lips for the 'r'.

m/m/

Press your lips together. Air flows through your nose. Vocal cords vibrate.

Common pronunciation mistakes in American English.

The textbook way isn't wrong — it's just not how anyone actually says it.

01

Stressing the wrong syllable.

Stress falls on the second syllable, not the others. Stretch LARM — keep everything else short and quick.

UH·larmuh·LARM
02

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.

UH·LARMuh·LARM
03

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