The standard pronunciation of “caricature” in English is:

  • UK: /ˈkær.ɪ.kə.tʃəː/ – roughly: KARR‑ih‑kə‑cher
  • US: /ˈker.ə.kə.tʃʊr/ – roughly: KAIR‑uh‑kə‑chur

So you can say it like:

  • “KARR‑ih‑kə‑cher” (more British)
  • “KAIR‑uh‑kə‑chur” (more American)

Both are correct; it just depends on your accent.
