Acoustic Phonetic Analysis

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 onse

Discourse Completion Task

The discourse completion task (DCT) is an elicitation instrument widely used in pragmatics to gather data on how people perform speech acts such as requests, apologies, refusals, and compliments. Respondents read short descriptions of situations and write (or say) what they would utter in each, allowing researchers to

Language Attitude Survey

A direct language attitude survey measures what people think and feel about languages, dialects, and varieties by asking them explicitly. Using questionnaires built from Likert scales, semantic-differential items, and open-ended questions, the direct approach gathers respondents' self-reported evaluations of varieties

Munsell Soil Color

Munsell soil color recording is the standard method for describing the color of soils, sediments, and artifacts in archaeology and geoarchaeology using Albert Munsell's perceptually ordered color system. Rather than relying on subjective names like 'brown' or 'tan,' the analyst matches a sample to printed color chips a

Sociophonetic Analysis

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 correlat

Vowel Formant Analysis

Vowel formant analysis is the acoustic measurement workflow for characterizing vowel quality. Vowels are resonances of the vocal tract, and their identity is carried by the formants — the spectral peaks created by those resonances. The first formant F1 is inversely related to vowel height (low F1 for high vowels, high
