How to pronounce susceptibility in American English
suh·sehp·tuh·BIH·luh·tee
Start here
Americans pronounce susceptibility as suh-sehp-tuh-BIH-luh-tee (/səˌsɛptəˈbɪləɾi/). In "susceptibility", the "t" between vowels sounds like a quick "d" — the tongue briefly taps the ridge behind the upper teeth. This is called the Flap T, and it's why Americans sound more relaxed than the textbook. It comes out as suh·SEHP·tuh·BIH·luh·tee. Stress falls on the fourth syllable — keep everything else short and quick. You'll hear it in sentences like "Genetics plays a significant role in susceptibility to certain diseases".

Common pronunciation mistakes in American English.
The textbook way isn't wrong — it's just not how anyone actually says it.
01
Saying a hard "T" in the middle.
In "susceptibility", the "t" between vowels sounds like a quick "d" — the tongue briefly taps the ridge behind the upper teeth. /t/ or /d/ becomes a quick tap [ɾ] — sounds like a soft D. The tongue briefly taps the ridge behind the upper teeth.
suh-sehp-tuh-BIH-luh-tee→suh·SEHP·tuh·BIH·luh·tee
02
Releasing the final consonant with a puff of air.
In "susceptibility", 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.
susceptibility→suh·SEHP·tuh·BIH·luh·tee
03
Stressing the wrong syllable.
Stress falls on the fourth syllable, not the others. Stretch BIH — keep everything else short and quick.
SUH·SEHP·TUH·bih·LUH·TEE→suh·SEHP·tuh·BIH·luh·tee
04
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.
SUH·sehp·tuh·BIH·luh·tee→suh·SEHP·tuh·BIH·luh·tee
Questions
Questions people ask about this.
How is "susceptibility" stressed in American English?
Stress falls on the fourth syllable — say "BIH" with a longer, fuller vowel and keep every other syllable short and quick. The respell "suh-sehp-tuh-BIH-luh-tee" marks the stressed syllable in capitals so the rhythm is easy to read at a glance.
Why doesn't the T sound like a T in "susceptibility"?
In American English, when /t/ sits between two vowels with the second one unstressed, it turns into a quick D-like flap. So "susceptibility" sounds closer to "suh-sehp-tuh-BIH-luh-tee" than to a crisp-T pronunciation. This is the flap-T rule, one of the most distinctive sounds of casual American speech.
Why does the first syllable in "susceptibility" 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 "suh-sehp-tuh-BIH-luh-tee" shows the reduced form so you can hear the casual rhythm directly.
Is the American pronunciation of "susceptibility" 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 "suh-sehp-tuh-BIH-luh-tee" reflects the casual American form; British dictionaries typically print a citation form with crisper consonants and different vowel choices.
