The pronunciation of "acetaminophen" is typically:
- In American English: /əˌsiː.t̬əˈmɪn.ə.fən/ which sounds like "uh-see-tuh-MIN-uh-fen"
- In British English: /əˌsiː.təˈmɪn.ə.fen/ which sounds like "uh-see-tuh-MIN-uh-fen"
The stress is on the fourth syllable "min" in both pronunciations. The "t" sound can be a soft flap sound in American English (similar to the "d" in "cutting") and a clear "t" in British English.
In simpler phonetic terms: uh-see-TUH-min-uh-fen.
