"Phonetic" refers to the study of sounds in human speech. It focuses on how sounds are produced, transmitted, and perceived. Phonetics is essential for understanding languages, as it helps in analyzing the pronunciation of words and the differences between various dialects. In phonetics, there are three main branches: articulatory phonetics, which examines how speech sounds are made; acoustic phonetics, which studies the physical properties of sound waves; and auditory phonetics, which looks at how sounds are heard and processed by the brain. This field is crucial for linguists, language learners, and speech therapists.
