How to pronounce biologists in American English
bahy·AH·luh·juhsts
Start here
Americans pronounce biologists as bahy-AH-luh-juhsts (/baɪˈɑlədʒəsts/). In "biologists", 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, the kind of sound shift that makes everyday speech feel effortless. It comes out as bahy·AH·luh·juhsts. Stress falls on the second syllable — keep everything else short and quick. You'll hear it in sentences like "Marine biologists study the health of the ocean".

ahy/aɪ/
Start with your jaw open wide and your tongue resting low and flat. Glide the front of your tongue up toward the roof of your mouth as your jaw closes halfway.
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.
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.
j/dʒ/
Touch the front of your tongue to the roof of your mouth, then release into a 'zh' position. Add vocal cord vibration.

Common pronunciation mistakes in American English.
The textbook way isn't wrong — it's just not how anyone actually says it.
01
Pronouncing the T in a consonant cluster.
In "biologists", 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. /t/ is dropped entirely — the surrounding consonants flow together without the T.
biologists→bahy·AH·luh·juhsts
02
Stressing the wrong syllable.
Stress falls on the second syllable, not the others. Stretch AH — keep everything else short and quick.
BahY·AH·LUH·JUHSTS→bahy·AH·luh·juhsts
03
Pronouncing the unstressed syllable too fully.
Don't pronounce the second syllable too fully. The unstressed syllable reduces to a schwa — the lazy "uh" sound — in casual speech.
bahy·AH·LUH·juhsts→bahy·AH·luh·juhsts
Questions
Questions people ask about this.
How is "biologists" stressed in American English?
Stress falls on the second syllable — say "AH" with a longer, fuller vowel and keep every other syllable short and quick. The respell "bahy-AH-luh-juhsts" marks the stressed syllable in capitals so the rhythm is easy to read at a glance.
Why does the third syllable in "biologists" 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 "bahy-AH-luh-juhsts" shows the reduced form so you can hear the casual rhythm directly.
Is the American pronunciation of "biologists" 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 "bahy-AH-luh-juhsts" reflects the casual American form; British dictionaries typically print a citation form with crisper consonants and different vowel choices.
