Judgment of intoxication using hybrid analysis with pitch contour compare (HAPCC) in speech signal processing

초록

Research on the estimation of body condition through voice analysis has been carried out to date. One of the reasons why your body suddenly changes is drinking. Drinking causes changes in the body and changes in the voice. Characteristics such as pitch, formant, and change of sound size are studied as parameters to discriminate between alcohol and alcohol, and voice before and after drinking is discriminated through high frequency and low frequency change of voice signal. In this paper, we investigated the alcohol discrimination method by comparing the change of voice signal before and after drinking using the changing vocal cord characteristics. By applying the pitch container to the musculature, the results of the drinking survey obtained various characteristics. © Research India Publications.
