Continued from the preceding article, the time series of clipped Japanese voiceless stop and fricative sounds are represented and compared with sonagrams and other data. As a result, it was recognized that clipped speech, to some extent, holds the important informations of hub of consonants, F_2 locus of following vowels, etc. . The sonagrams of stop and fricative sounds have the characteristic feature of spike fill or fill, but in clipped speech differentiated before clipping, by the character which dominant parts are emphasized, spike fill or fill generally do not appear and show distinctive feature like formant. The sub and F_2 locus of |p| are influenced by following vowels and, to some extent, give actual proof of the results obtained by vocal tract analog by Stevens and House. Mishearing may be due to the transition of following vowels as well as the distribution of turbulent parts and each cause of mishearing in clipped speech can be made clear. Turbulent parts of some stop as well as fricative sounds have time variation in the distribution of their zero crossing intervals.
