How is "impact" stressed in American English?

Stress falls on the first syllable — say "IHM" with a longer, fuller vowel and keep every other syllable short and quick. The respell "IHM-pakt" marks the stressed syllable in capitals so the rhythm is easy to read at a glance.

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.
