Phonetic refers to the sounds of language or speech. It involves the way words are pronounced and the different phonemes that make up a language.
Phoneme: A unit of sound in a language that distinguishes one word from another. For example, "cat" and "bat" differ by only one phoneme (/k/ vs /b/).
Articulation: The physical process of producing speech sounds.
Pronunciation: The way in which a word or language is spoken, including its accent, stress patterns, and intonation.
