What does phonetics mean?
Phonetics is the branch of linguistics that studies speech sounds as physical phenomena. It examines how the lips, tongue, vocal cords, and other parts of the speech apparatus produce sounds, as well as how listeners perceive differences among those sounds. Phonetic research can involve acoustic analysis, articulatory descriptions, transcription, and comparison of pronunciation across languages. The field is especially useful to students of languages, linguistics, speech therapy, education, and language teaching. Although phonetics and phonology are related, they have different emphases: phonetics focuses largely on the measurable and articulatory properties of sounds, while phonology examines the abstract patterns and contrasts that distinguish words in a particular language. Phonetics is therefore both a scholarly discipline and a practical foundation for understanding and improving pronunciation.
nounThe branch of linguistics concerned with the physical production and perception of speech sounds, including how sounds are articulated and how they vary between speakers, languages, and contexts.

Etymology of phonetics
The word comes from Greek phōnē, meaning “voice” or “sound,” combined with the adjective suffix -etikos, meaning “pertaining to” or “relating to.” Its modern sense developed through the tradition of linguistic study concerned with the pronunciation and articulation of speech sounds. The related word phonology was formed through a different suffix, -logia, meaning “study of,” and has traditionally focused more on the organization of sound systems.
