Phonetics is a branch of linguistics focused on the production, nature, and reception of speech sounds, including articulatory, acoustic, and auditory subfields. In contrast, phonology studies the systems and patterns of speech sounds within a specific language. The document outlines the differences between phonetics and phonology, emphasizing their distinct focuses on speech sounds and their characteristics.

2. Phonetics
Phonetics, a branch of linguistics is concerned
with the scientific study of the production, physical
nature, and reception of speech sounds.
Basically, it studies the medium of spoken
language.

3. The Things It Deals with
It deals with configurations of the vocal tract
used to produce speech sounds (articulatory
phonetics), the acoustic properties of speech
sounds, and the manner of combining sounds as to
make syllables, words, and sentences (linguistic
phonetics).

4. How Does It Look at Speech?
It looks at speech from three distinct but
interconnected viewpoints: it studies –
 the speech organs, which produce sounds of language;
 waves, the physical form in which sounds are
transmitted through air from one person to another;
 the way in which human beings perceive sounds through
the medium of ear.

6. Branches of Phonetics
1. Articulatory Phonetics, deals with the way in which speech sounds
are produced. Sounds are usually classified according to the position
of the lips and the tongue, how far open the mouth is, whether or not
the vocal cords are vibrating.
2. Acoustic Phonetics, deals with the transmission of speech sounds
through air form one person to another. When a speech sound is
produced it causes minor disturbances. Various instruments are used
to measure the characteristics of these sound waves.
3. Auditory Phonetics, deals with how speech sounds are perceived by
the listener.

7. Phonology
Phonology is the study of the system or pattern of speech sounds in a
particular language.
What is sound? How and where is it produced from? How is it received
by the ear? How and why is one sound different from the other?- questions like
these are the subject-matter of phonology.
