Common pronunciation mistakes in American English.
The textbook way isn't wrong — it's just not how anyone actually says it.
Pronouncing the silent T after N.
In "interfered", the "t" right after N is dropped — the tongue skips the T stop and moves directly from the N position to the next sound. /t/ is completely silent — the tongue skips the T stop and moves directly from the N position to the next sound.
Releasing the final consonant with a puff of air.
In "interfered", the "" 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.
Stressing the wrong syllable.
Stress falls on the third syllable, not the others. Stretch FEERD — keep everything else short and quick.
Pronouncing the "R" too clearly.
Americans use a relaxed retroflex R — the tongue curls back rather than rolling. The R is one continuous sound with the vowel before it, not two separate sounds.
