| 摘要: | 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. | |
