The open mouth's MVP, the sound that escapes when nothing gets in its way.

means A speech sound made with an open vocal tract so the breath flows freely (in English, typically a, e, i, o, u, and sometimes y), forming the core of a syllable.

from From Latin vocalis, 'vocal, sounding,' from vox, 'voice' — literally 'the sounding letter.' It reached English through Old French vouel before settling into 'vowel,' and vox itself is a deep relative of words like 'voice' and 'vocation.'
