How to pronounce incredible in American English
uhn·KREH·duh·buhl
Start here
Americans pronounce incredible as uhn-KREH-duh-buhl (/ənˈkrɛdəbəl/). In "incredible", 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, the kind of sound shift that makes everyday speech feel effortless. So instead of uhn·KREH·tuh·buhl, you get uhn·KREH·duh·buhl. Stress falls on the second syllable — keep everything else short and quick. You'll hear it in sentences like "The rover sent back incredible data from the surface of the planet".

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 "incredible", 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.
uhn-KREH-tuh-buhl→uhn·KREH·duh·buhl
02
Treating every L the same.
The L in "incredible" is a dark L — the back of the tongue rises toward the soft palate, adding a small "uh" quality before the L. Dark L adds a small schwa-like "uh" before the L. The back of the tongue lifts toward the soft palate.
incredible→uhn·KREH·duh·buhl
03
Stressing the wrong syllable.
Stress falls on the second syllable, not the others. Stretch KREH — keep everything else short and quick.
UHN·kreh·DUH·BUHL→uhn·KREH·duh·buhl

Pronouncing the first syllable too fully.

Questions
Questions people ask about this.
How is "incredible" stressed in American English?
Stress falls on the second syllable — say "KREH" with a longer, fuller vowel and keep every other syllable short and quick. The respell "uhn-KREH-duh-buhl" 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 "incredible"?
In American English, when /t/ sits between two vowels with the second one unstressed, it turns into a quick D-like flap. So "incredible" sounds closer to "uhn-KREH-duh-buhl" 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 "incredible" 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 "uhn-KREH-duh-buhl" shows the reduced form so you can hear the casual rhythm directly.
Is the American pronunciation of "incredible" 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 "uhn-KREH-duh-buhl" reflects the casual American form; British dictionaries typically print a citation form with crisper consonants and different vowel choices.
