This is an advanced and detailed study of timbre pattern of oral vowels, treating especially pattern shape from peak and glen structures, and, at the same time, endeavoring to clarify the meaning of the so-called formant in its broadest meaning. Our study of timbre pattern begins with the selection of two calling subjects having contrasting nasal cavity conditions: one in perfect free state and the other in an inherent partially blocked state. Thus we can fully investigate and discuss the problem of perfectiveness and imperfectness of absorbing performance of nasal cavity in formation of oral vowels issued exclusively through buccal-cavity passage. Conspicuous contrast is found between the timbre patterns of our two callers, particularly when timbre patterns are obtained under the condition of level forcing which is accompanied by pitch change.
