IPA: //ʌnˈvɔɪst//
KK: /ʌnˈvɔɪst/
Describing a sound that is produced without the vocal cords vibrating, or something that is not expressed in words.
The unvoiced consonants in English include sounds like 'p' and 't'.
Unvoiced → It is formed from "un-" (meaning not) and "voiced" (from Latin "vox", meaning voice). The word "unvoiced" means not having a voice or sound, often used in phonetics to describe sounds produced without vocal cord vibration.
Think of 'not' ('un-') having a 'voice' ('voiced') — that's why unvoiced means lacking sound.
