خلاصه	Sociophonetic analysis sits at the intersection of acoustic phonetics and variationist sociolinguistics. It applies the precise, quantitative measurement of phonetic variables — vowel formants, voice onset time (VOT), the spectral moments of /s/, and many others — to socially structured samples of speech, then correlates those measurements with social factors such as age, social class, gender, ethnicity, and region. The result is a fine-grained, statistically defensible account of how phonetic detail carries social meaning and how it patterns across communities and across time, increasingly built on large-scale, automated measurement.	Acoustic phonetic analysis is the empirical measurement workflow at the heart of experimental phonetics: it records speech, segments and labels the signal, and extracts quantitative acoustic parameters — the waveform, the spectrogram, fundamental frequency (F0), the formants, intensity, segment duration, and voice onset time (VOT). These measurements are interpreted through the source-filter theory of speech production, which models the output sound as a glottal source spectrum shaped by the transfer function of the vocal tract, turning the audible speech stream into reproducible numbers that can be compared, modelled, and related to articulation.
