English has its own form of karaoke. It is ker-ee-OH-kee in the US and ka-ree-OH-kee in Britain, with the stress on OH and a final kee. Japanese speakers say kah-rah-oh-keh, with an even rhythm, and that is not the English form.
The word is Japanese. Kara means empty, and oke is short for okesutora, the Japanese word for orchestra. So karaoke means empty orchestra: the music plays without the singer.
Say the first two syllables quickly and lightly, stress the third, and finish with kee. Many learners say kuh-RAW-kee, which drops a syllable.
