Concepts of Voiced and Unvoiced sounds.

 In phonetics, sounds are divided into two main categories: voiced sounds (voiced) and unvoiced sounds (unvoiced). The difference between these two types of sounds lies in the vibration of the vocal cords when producing them.

Voiced sounds, also known as voiced sounds, are those in which the vocal cords vibrate when articulated. These vibrations create a resonant sensation in the throat, which gives them their "voice" characteristic. Examples of voiced sounds in English are /b/, /d/, /g/, /v/, /z/, /th/ as in "the", /l/, /m/, /n/, /ng /, /r/, /y/, /w/.

On the other hand, voiceless sounds, also known as voiceless sounds, are those in which the vocal cords do not vibrate when articulating them. These sounds tend to be higher pitched and less resonant than voiced sounds. Examples of unvoiced sounds in English are /p/, /t/, /k/, /f/, /s/, /sh/, /ch/, /th/ as in "think", /h/.

The distinction between voiced and unvoiced sounds is fundamental in the phonology of a language, since it affects the understanding and production of speech. In many languages, such as English, the presence or absence of vocal fold vibration can change the meaning of a word. For example, in English, the word "pat" (/pæt/) is distinguished from the word "bat" (/bæt/) only by the initial sound, in this case, the presence or absence of vocal fold vibration. . .
