Compute the Vowel space density from formant values

Description

This function computes the Vowel space density from a vector of F_1 and F_2 measurements based on the algorithm of \insertCitationStory.2017.10.1121/1.4983342articulated.

Usage

VSD(F2, F1, resolution = 0.05, grid.res = 0.01, density.threshold = 0.25)

Arguments

F2

A vector of F2 formant frequency measurements, one for each measure vowel.

F1

A vector of F1 formant frequency measurements, one for each measure vowel.

resolution

The distance on the normalized F2-F1 space within which vowels will be counted towards the tally of vowels in close proximity for the point.

grid.res

The spectral resolution of the analysis.

density.threshold

The fraction of the maximum density of vowels below which the density will be considered zero.

Value

The vowel space area (in Hz^2).
