Glottals
There is one sound that is produced without the active use of the tongue and
others parts of the mouth.
Consonant sound
Stops
A consonant sound where the airflow is stopped completely by the mouth and then
sharply released. Think of sounds like “p,” “k,” and “t.” All languages contain stops.
Fricatives
a consonant sound where the airflow becomes noisy and turbulent because it only
has a very small space to travel through in the mouth. Think of sounds like “f,” “s,”
and “sh.” Most languages have fricatives, but not all.
