Pronunciation

How to pronounce “impact”

“impact” has two pronunciations: /ˈɪmpækt/ as a noun and /ˌɪmˈpækt/ as a verb — the part of speech decides which. The spelling never changes; the beat does, and the vowels reshape around wherever it lands. The transcription and syllable breakdown below describe the noun form.
Two pronunciations

“impact” is said two ways

As a noun

/ˈɪmpækt/

IM-pakt

The effect, or the collision. Beat on IM.

As a verb

/ˌɪmˈpækt/

im-PAKT

To strike, or to affect. Beat on PAKT.

Listen for the beat, not the letters

One syllable gets longer, louder and a step higher, and the other one collapses towards a schwa. Say the whole sentence rather than the word on its own and let the grammar pull the beat where it belongs.Both forms live in one sentence here: “Rate rises impact spending, and that impact reaches every shop.”

Each button plays a short phrase rather than the bare word: the model voice takes its stress from the words around it, so asking it for “impact” on its own would play one reading twice instead of the noun and the verb. Read the transcription as you listen.

Accents

American and British are not the same here

This is the noun form in two accents — a separate question from the two pronunciations above, which are the same accent saying two different words.

American

/ˈɪmpækt/

British

/ˈɪmpakt/

No audio here: sayit’s voice is American, so a British button would play the American word. Read the transcription instead.
