k/k/
Raise the back of your tongue to touch the soft palate (velum). Stop the air, then release.
s/s/
Place your tongue tip near the roof of your mouth behind your top teeth. Push air through the narrow gap. No voicing.
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.
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.
ay/eɪ/
Start with your jaw slightly open and the front of your tongue forward and slightly up. Glide upward, your jaw closes a little more and your tongue arches higher toward the roof of the mouth.
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.

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 SEH — keep everything else short and quick.
UHK·seh·LUH·RAYT→uhk·SEH·luh·RAYT
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.
UHK·SEH·luh·rayt→uhk·SEH·luh·RAYT
Questions
Questions people ask about this.
How is "accelerate" stressed in American English?
Stress falls on the second syllable — say "SEH" with a longer, fuller vowel and keep every other syllable short and quick. The respell "uhk-SEH-luh-rayt" marks the stressed syllable in capitals so the rhythm is easy to read at a glance.
Why does the first syllable in "accelerate" 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 "uhk-SEH-luh-rayt" shows the reduced form so you can hear the casual rhythm directly.
Is the American pronunciation of "accelerate" 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 "uhk-SEH-luh-rayt" reflects the casual American form; British dictionaries typically print a citation form with crisper consonants and different vowel choices.
