摘要	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.	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.
