What kind of consonant is called “stop” and what makes a stop different from a fricative?
a. Stop consonants are consonants that contain the following characteristics:
– One articulator is moved against another, or 2 articulators are moved against each other so as to form a stricture that allows no air to escape from the vocal tract
– After this stricture has been formed and air has been compressed behind it, it is released that is air is allowed to escape.
– If the air behind the stricture is still under the pressure, when the plosive is released, it is probable that the escape of air will produce noise loud enough to be heard. This noise is called plosion.
– There may be voicing during part or all of the plosive articulation
b. What makes a stop different from a fricative is that you can continue making fricative without interruption as long as you have enough air in your lungs. It means that fricatives are continuant consonants, plosives are not continuant.
