A Judgment of Intoxication using Pitch Contour Compare Signal(PCCS)

초록

Research for estimating body condition through voice analysis has been carried out until now. One of the causes for the abrupt changes of body condition is the drinkmg. Drinking makes changes in the body and also to the voice. Those researches study about pitch and formant, the two parameters for determining drinking and characteristics such as variation in size of the sound. Moreover, sound before and after drinking is determined through the changes in high frequency and low frequency of the voice signal. This research tries to fmd how to determine drinking by comparing variation in voice signals before and after the drinking by analysing vocal cord which changes when drinking. © International Information Institute.
