Questions on Greek and Hebrew?

In Japanese, sentences are like 'IChi ni san shi go roku" and the langauge reminds me of bees buzzing. Chinese frequently using the "ng" sound and remidns me of babytalk. Spanish overuses the "O" sound at the end of words and sounds like a machine gun. What are Hebrew and Greek like in this sense? What syllables and vowels are msot common in Hebrw or Greek?
