Organs of Speech: Kadirova Aruzhan, Molzhigitov Maka, Vladimir Shilovskii

The document summarizes the main organs of speech, which are divided into three systems: 1) the respiratory system including the lungs, chest muscles, and windpipe; 2) the phonatory system including the larynx and vocal cords; and 3) the articulatory system including the nose, mouth, lips, teeth, hard and soft palates, and tongue. It then provides more details on the larynx, vocal cords, roof of the mouth, and how the state of the glottis and soft palate determine if sounds are voiced, voiceless, nasal, or nasalized.

Phonetics

❑ Phonetics is the study of the medium of spoken


language, that is, the production, transmission
and reception of the sounds of human speech.
❑ Spoken language is produced by the
movements of the organs of speech.
❑ All human beings have the same organs of
speech. So, theoretically speaking, every
normal human being can produce any of the
sounds of human speech.
The Organs of Speech

❑ The respiratory system, consisting of the lungs,


the muscles of the chest, and the windpipe
(trachea)
❑ The phonatory system, formed by the larynx
❑ The articulatory system, consisting of the nose,
the mouth (including the tongue, the teeth, the
roof of the mouth, and the lips)

The Organs of Speech
The larynx

❑ The air from the lungs comes through the


windpipe or trachea, at the top of which is the
larynx.
❑ In the larynx are two vocal cords, which are like
a pair of lips placed horizontally from front to
back.
❑ They are joined in the front, but can be
separated at the back, and the opening
between them is called the glottis.
The roof of the mouth

❑ The roof of the mouth can be subdivided into four


parts:
– the teeth-ridge or the alveolar ridge, i.e., the hard convex
surface just behind the upper front teeth
– the hard palate, i.e., the hard concave surface behind the
teeth-ridge
– the soft palate, i.e., the soft portion behind the hard palate
– the uvula, i.e., a small fleshy structure at the end of the soft
palate

The State of the Glottis

❑ When we breath in and out, the glottis is open.


That is, the vocal cords are drawn wide apart
producing voiceless sounds.
❑ If the vocal cords are held loosely together, the
pressure of the air coming from the lungs
makes them vibrate; that is, they open and
close regularly many times a second. Sounds
produced in this way are called voiced
sounds.
