Debuccalization, or deoralization, is a sound change or alternation in which an oral consonant loses its original place of articulation and moves it to the glottis (, , or ). The pronunciation of a consonant as is sometimes called aspiration, but in phonetics, aspiration is the burst of air accompanying a stop. The word comes from Latin , meaning 'cheek' or 'mouth'.

Debuccalization is usually seen as a subtype of lenition, which is often defined as a sound change involving the weakening of a consonant by progressive shifts in pronunciation. As with other forms of lenition, debuccalization may be synchronic or diachronic (i.e. it may involve alternations within a language depending on context or sound changes across time).
