【正确答案】Phonetics is defined as the study of the phonic medium of language; it is concerned with all the sounds that occur in the world's languages. Phonetics looks at speech sounds from three distinct but related points of view. First, it studies the sounds from the speaker's point of view, i.e., how a speaker uses his speech organs to articulate the sounds. Then it looks at the sounds from the hearer's point of view, i.e., how the sounds are perceived by the hearer. Lastly, it studies the way sounds travel by looking at the sound waves, the physical means by which sounds are transmitted through the air from one person to another. These three branches of phonetics are labeled articulatory phonetics, auditory phonetics, and acoustic phonetics.
Phonology, however, is interested in the system of sounds of a particular language; it aims to discover how speech sounds in a language form patterns and how these sounds are used to convey meaning in linguistic communication. Phone, phoneme, allophone, phonemic contrast, complementary distribution, minimal pair, phonological rules, suprasegmental features, etc. are all to be investigated by phonologists.
