Common pronunciation mistakes in American English.
The textbook way isn't wrong — it's just not how anyone actually says it.
Inserting a vowel before the syllabic consonant.
In "invention", the short unstressed vowel before "n" disappears — the schwa is absorbed and the "n" becomes the syllable nucleus on its own. Schwa is absorbed — consonant becomes the syllable nucleus.
Stressing the wrong syllable.
Stress falls on the second syllable, not the others. Stretch VEHN — keep everything else short and quick.
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.
