Translation:Aloha e Kaʻiulani.
The ' is a glottal stop! It's pronounced sort of like a quick pause, and it functions like any other consonant. It's not a distinct speech sound in English, but it's the pause between the vowels in "uh-oh", for example, and in certain British dialects, it can replace t's.
I'm stressing the 1st syllable, then the 3rd syllable a bit less. But only because that sounds most Hawai'ian to me. And the ' on Hawai'i I've heard native Hawai'ian speakers say it as a pause at beauty pageants.
