ABSTRACT
In this chapter, I report the results of an acoustic case study designed to test the hypothesis put forth in earlier chapters, that the Guttural OCP constraint in Ju∣'hoansi has its basis in perception. That is, I explicitly test the hypothesis that all guttural vowels display a high degree of noise in their C-V transition and that guttural consonants display similar spectral noise in the C-V transition through guttural coarticulation. I investigate the dimensions of periodicity represented by the gamnitude of the first rahmonic peak (Hillenbrand et. al., 1994) and the PPQ measure of jitter (Davis, 1976), as well as the dimension of spectral slope represented by the difference between the amplitudes of the first and second harmonics (H1-H2) (Bickley, 1982).
