Leaving out the ʻokina and kahakō changes the sound significantly. The ʻokina represents a glottal stop, the sound in the middle of "uh-oh". In Hawaiian, it's a letter of the alphabet. The kahakō (macron, the horizontal line over a vowel) means the vowel is long - as in pronounced for a beat longer. What we call long and short vowels in English should be considered different vowels because they are different sounds.
