• To devoice — To deprive of sound, echo, or sonorous properties; to transform a voiced sound into a voiceless one by stopping the vibration of the vocal cords. In modern acoustic engineering, the term is used very rarely to describe the complete attenuation of sound emissions.
• Devoicing — The act of devoicing or deadening sound; the process of transforming a voiced sound into a voiceless one by stopping vocal cord vibration during articulation. In audio engineering, it describes the extreme attenuation of sound waves or the mitigation of resonance within an acoustic chamber.
