IDENTIFYING VOICE CHARACTERISTICS AMONG VARIOUS ETHNICITIES THROUGH SPECTROGRPHIC ANALYSIS AND ACOUSTIC PHARYNGOMETRY

摘要

What characteristics of the human voice identify its unique print? Furthermore, what are the idiosyncrasies of an individual's body that create this unique voice print? An African-American man's physiology and anatomy will most certainly differ from the physiology of an Asian-American man. If two men from different ethnicities have different physiological compositions, could we expect to hear differences in their voices? Excluding dialectical differences, can we identify these differences in their voice prints? Among many variables, the physiology of the person's body may alter the results of a forensic spectrographic analysis, and will potentially appear in an acoustic pharyngometry test. In this paper, we will survey existing research on voice identification and our own spectrographic analysis, as well as research in the field of speech and voice anatomy to determine whether different ethnic groups have different physiological vocal resonators, and if this can be identified.
