Phonetic Analysis of Clicks, Plosives and Implosives of IsiXhosa: A Preliminary Report
This pilot study examined the effectiveness of locus equations in differentiating places of articulation among stop consonants (clicks, plosives and implosives) in IsiXhosa in the context of the vowel /a/. The results obtained showed that the slope values for the dental and the postalveolar clicks are similar and shallower than that of the lateral click. Velar stops (plosives, implosives and ejectives) exhibited a steeper slope than either the bilabial or the dental stops. These results suggest that locus equations may be effective at distinguishing places of articulation for a variety of stop consonants.
