Abstract
This study analyses locus equations and regression lines relating to second and
third formants as a measure of co-articulatory influence of vowels following stop
consonants in EkeGusii. Coarticulation can be represented statistically using a schematic
representation of locus equations by tracking consonant-vowel (CV) transition as a useful
tool in the discrimination of place of articulation. Acoustic data was collected using Praat
version 6.0 from four males and four females, native speakers of EkeGusii. Locus
equations for the eight speakers were derived from CV words with intervocalic voiceless
bilabial /p/, voiceless alveolar /t/ and voiceless velar /k/ preceding vowel /i/, /a/ and /o/
contexts. Scatter plots of locus equation of F2 and F3 onsets-F2 and F3 midpoints revealed
patterns for each of the three voiceless stops in EkeGusii. The strongest degree of
coarticulation is reported for velars then bilabials and the least degree of coarticulation with
alveolars.
