< Figure of one part of element 1
of utterance japanese vowel "A">
In figure above, set of mark + represents one part of
element
1 of utterance japanese vowel "A." Comparing to a formula
consisted of exp * sin waves, it consists of waves of
which level and cycle is
unstable. Maybe, glottis movement (period of shut up, opening,
and shutting) may reflect its change.
If fundamental frequency wave information is lost in
communication transmission, it is able to be roughly gotten by
analysis of Element.
And localized portion of the wave can be approximated to a
combination of two sin waves of which frequency differs means
that the wave may be generated from spaces connecting each other.
Consisting of a
combination of two sin waves is important. Because by relation of
the two waves, it may be estimated what place of space the signal
occurs.
