The process of removing voice, sound, or vocal qualities from something; in linguistics, removing voicing from a sound.
From de- (removal) + vocalisation (British spelling), from Latin vocalis (pertaining to voice, from vox meaning voice).
In phonetics, devocalisation is what happens when you whisper—your vocal cords stop vibrating, so a 'b' sound becomes more like a 'p' sound because you've removed the voicing.
