Question

________ is the sound when there is an explosive release of air after it comes in contact with parts of the speech mechanism

Answer 1

Aspirated consonant: When a plosive or fricative pronounced with a strong burst of air.

Aspiration is referred to as the strong burst of breath in phonetics

Consonants: The words which obstruct breath partially are referred to as consonants. They form syllables when they combine with vowels.  

Hence, Aspirated consonant is the sound when there is an explosive release of air after it comes in contact with parts of the speech mechanism.
