Conclusion
In phonetics and phonology, articulation is
the movement of the tongue, lips, jaw, and other speech organs in
ways that make speech
sounds.
Sound
is produced simply by expelling air from the lungs. However, to vary
the sound quality in a way useful for speaking, two speech organs
normally move towards each other to contact each other to create an
obstruction that shapes the air in a particular fashion. The point of
maximum obstruction is called the place
of articulation,
and the way the obstruction forms and releases is the manner
of articulation.
For example, when making a p sound,
the lips come together tightly, blocking the air momentarily and
causing a buildup of air
pressure.
The lips then release suddenly, causing a burst of sound. The place
of articulation of this sound is therefore called bilabial,
and the manner is called stop (also
known as a plosive).
Articulation
can be shown with magnetic
resonance imaging to
demonstrate how the tongue, lips and jaw move and the rise and fall
of thesoft
palate.
Such movement alters resonant properties of the vocal tract, and
imposes a "time-varying formant structure" onto the speech
signal. The
study of articulation in making speech is called articulatory
phonetics.
