vowelspace.center: Computes the center of a vowel space.

In FredrikKarlssonSpeech/articulated: This package adds

Computes the center of a vowel space.

Description

Two methods are implemented. In the default method, a mean F_1 value are calculated in an initial stage, and separate F_2 means are then computed for points above a line y=mean(F_1), and one mean for values below that line. The F_2 value for the center point is then computed as the mean of the upper and lower mean F_2 values. The "wcentroid" method simply averages the F_2 and F_1 values and return that as the center point. The first method is preferable, as vowel spaces in a triangular shape are otherwise quite likely to have center points outside of the vowel triangle.

Usage

vowelspace.center(f1, f2, method = "wcentroid", na.rm = TRUE)

Arguments

f1	The F_1 values of vowels.
f2	The F_2 values of vowels.
method	The method to use. Could be either one of "centroid" or "twomeans" (the default).
na.rm	Boolean indicating whether NA:s should be removed in the calculations of mean values.

Value

A list containing the F_2 and F_1 values of the vowel space center.
