Close-mid back rounded vowel to Glottal stop

The shift from the vowel [o] to a glottal stop [ʔ] is a universal phonetic process known as glottal reinforcement or 'hard attack'. It occurs when a word begins with the vowel, and the speaker inserts a glottal stop to clearly separate it from the preceding speech stream or to emphasize the word.
