Sorry if i misunderstood your question
Consonants are letters in the alphabet that make a sound when they are pronounced. These letters can be grouped into three broad categories:
Voiced consonants: These are sounds that are made with the use of the vocal cords. Some examples of voiced consonants are /g/, /k/, /b/, and /p/.
Unvoiced consonants: These are sounds that are made without activation of the vocal cords. Some examples of unvoiced consonants are /f/, /s/, /m/, and /n/.
Aspirated consonants: These are sounds that have a breath of air released when they are pronounced.
