Ubbi dubbi works by adding -ub- /ʌb/ before each vowel sound in a syllable.[6] (A linguist would say "Insert [ˈʌb] after each syllable onset".)[7] The stress falls on the "ub" of the syllable that is stressed in the original word. So in "hello", which is stressed on the "-lo" syllable, the stress falls on the "lub" in "hubellubo".
