What is another word for glottal plosive?
Pronunciation: [ɡlˈɒtə͡l plˈə͡ʊsɪv] (IPA) 
A glottal plosive is a sound produced by a sudden closure of the glottis, which then releases a burst of air. This sound is often represented in writing with the symbol '?'. There are several other terms for this sound, including glottal stop, glottal catch, and vocalic comma. In some languages, such as Arabic and Hebrew, the glottal stop is a commonly used consonant and is represented by a specific written letter. However, in English, the glottal stop is often used in informal speech, such as in the Cockney accent, but is not a standard sound in the language.
