Abstract
It is known that speech sounds formed on the basis of phonemes have acoustic properties such as strength and weakness. We perceive the loudness of the speech sound as loudness or lowness according to our hearing. Specifically, when we listen to the radio, we ask them to turn it up (louder) or down. In consonants and vowels, strength-weakness occurs in a unique way.
