This is the vowel space data from a single speaker, s01, whose
audio interview and transcription are part of the Buckeye Corpus
(Pitt et al. 2007). The transcript was realigned to the audio using the
Montreal Forced Aligner (McAullife et al. 2022) and vowel formant data
extracted with FAVE (Rosenfelder et al. 2022).

datasets

With bivariate data, it is possible to calculate
2-dimensional kernel density estimates that return polygons at given
levels of probability. 'densityarea' returns these polygons for
analysis, including for calculating their area.
