Timbre study on nasalics : Part I-Symbolic description of timbre-Patterns of generalized vocalics

In our paper titled “Memoirs on Nasalics,” we have already discussed the problem of nasals from various points of view. From our standpoint of speech­communication, we look at this problem having in mind the following three objectives. (1) To clarify the role of nasal-cavity system in formation of oral vocalics. (2) To obtain the timbre structure of nasal sounds of various kinds, interpreting thereby the role of buccal-cavity system on the nasal cavity performance. (3) To coordinate the timbre axis of nasality in genealogic display of timbre in general. The distinguishing mark of our study on nasals is that we present a joint study of (1) and (2). For this purpose we had to ultimately deal with the characteristic circuit performance of bifurcated nature as well as with actual nasal phonemes in the phonological sense.
