Abstract
In this study, speech characteristics from before and after alcohol intoxication have been comparatively analyzed through speech analysis to obtain the degree of intoxication along with its parameters. The speech characteristics of an alcohol intoxicated person such as pitch and formant and changing of sound levels have been studied but the speech characteristics before and after alcohol intoxication cannot be analyzed because of the sensitiveness of environmental changes. Therefore, we need to find more precise parameters, especially, phonation threshold pressure, the high levels of which result in dehydration of the laryngeal mucous membrane after alcohol intoxication. Speech after alcohol intoxication is with low lung pressure and decreasing lung capacity. Thus, we study the speech characteristics from before and after alcohol intoxication using speech-rate in speech signal and lung capacity.
