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.
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.
f/f/
Lift your bottom lip to touch the very bottom of your top front teeth. Blow air through this contact point without voicing.
or/ɔr/
Start with the 'aw' jaw drop and rounded lips. Pull the tongue back and up while keeping the lips rounded for the R.
m/m/
Press your lips together. Air flows through your nose. Vocal cords vibrate.
z/z/
Same position as S, but add vocal cord vibration. Feel the buzz.

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 "platforms", 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.
platforms→PLAT·FORMZ
02
Stressing the wrong syllable.
Stress falls on the first syllable, not the others. Stretch PLAT — keep everything else short and quick.
plat·FORMZ→PLAT·FORMZ
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 "platforms" stressed in American English?
Stress falls on the first syllable — say "PLAT" with a longer, fuller vowel and keep every other syllable short and quick. The respell "PLAT-formz" marks the stressed syllable in capitals so the rhythm is easy to read at a glance.
How do I pronounce the R in "platforms"?
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 "platforms" 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 "PLAT-formz" reflects the casual American form; British dictionaries typically print a citation form with crisper consonants and different vowel choices.
