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