The [h] sound.
Let us first consider how the sound
[h] is produced. It is a good starting
point because {h} has a distinctive sound, produced at the glottis itself with
a puff of air. Therefore the place
of articulation is glottal. [h] is produced with the vocal cords pulled apart, therefore it
is voiceless. So we can
now determine that [h] is a voiceless glottal sound.
The [h] sound is also produced with
a continuous flow of air, therefore the manner of articulation is
fricative. Fricatives are
consonants that are produced with a continuous airflow through the mouth that
belong to a larger class of sounds called continuants.
Therefore [h] is a voiceless glottal fricative. It is produced when a puff of air is
emitted directly from the glottis with the vocal cords pulled apart and uses a
continuous airflow through the mouth.
