Abstract

Effects on the slope of introducing error in the F2 Hz values in locus equations (LEs) and of using fewer than ten vowels were investigated. For each of the initial consonants /b, d, g/, 2000 simulated sets were generated using Monte Carlo techniques. The sets were altered with 50, 100, or 200 Hz error being randomly applied to each F2 value within a set. Selected vowels were then removed from the sets and the effects on the slopes were measured. Results suggest that the LE slopes are generally resistant to error and reduced number of vowels. Effects of adding 50 Hz of random error to the F2 values in sets using eight or ten vowels were minimal, yielding a mean absolute change in slope less than 0.07.
