Abstract
Disclosed are a method for determining whether a person is drunk after consuming alcohol capable of analyzing alcohol consumption in a time domain by analyzing a voice, and a recording medium and a terminal for carrying out same. An alcohol consumption-determining terminal comprises: a voice input unit for generating a voice frame by converting an inputted voice signal and outputting the voice frame; a voiced/unvoiced sound analysis unit for determining whether the voice frame inputted through the voice input unit corresponds to a voiced sound, an unvoiced sound, or background noise; a voice frame energy detection unit for extracting the average energy of voice frames which have been determined as a voiced sound by the voiced/unvoiced sound analysis unit; an interval energy detection unit for detecting the average energy of intervals including a plurality of voice frames which have been determined as voiced sounds; and an alcohol consumption determining unit for determining whether a person is drunk after consuming alcohol by extracting a difference value among the average energy of neighboring intervals which have been detected by the interval energy detection unit, thereby determining whether a person is drunk after consuming alcohol by analyzing the voice signal in a time domain.
