Phonetics

Phonetics is the study of speech sounds as physical events: how they are produced by the vocal tract, transmitted through air, and perceived by listeners.

Articulatory phonetics: The study of how speech sounds are formed by movements and configurations of the vocal tract. It explains how tongue, lips, and other articulators produce the sounds phonetics describes.
Phoneme: A language-specific sound category that can distinguish words from one another. Phonetics studies physical sounds, while phonemes classify sound contrasts within particular languages.
Speech recognition: The computational conversion of spoken language into written or structured output. Recognition systems use acoustic patterns that phonetic analysis helps describe.
Phonology: The study of how languages organize speech sounds into systems and patterns. It explains sound patterns in language, complementing phonetics’ focus on physical realization.
Acoustic phonetics: The study of the physical properties of speech sounds as sound waves. It tracks how articulatory gestures become measurable patterns traveling through air.
Allophone: A context-dependent phonetic realization of a phoneme that does not change word identity. Allophones show how one phonological category can have multiple physical pronunciations.
Text-to-speech: Technology that generates spoken output from written text. Natural-sounding synthesis depends on modeling pronunciation, timing, and intonation.
Sociophonetics: The study of how social factors shape phonetic variation and speech perception. It connects measurable pronunciation differences with social identity and interaction.
Auditory phonetics: The study of how listeners hear and process speech sounds. It completes the production-to-perception chain central to phonetics.
Place of articulation: The location in the vocal tract where airflow is constricted to form a consonant. It organizes consonants by the articulators and surfaces involved in their production.
