摘要：
An alcohol consumption determination method includes detecting a plurality of effective frames of an input voice signal； detecting a difference in signal of within the original signal of each of the effective frames； detecting average energy of the original signal and average energy of the difference signal for each of the effective frames； and determining whether alcohol has been consumed based on a difference between the average energy of the original signal and the average energy of the difference between the signals for each effective frame. Accordingly, it is also possible to determine, from a remote location, whether a driver or an operator remote has consumed alcohol and the degree of inebriation by using a difference signal energy method using a voice signal, thus preventing an accident caused by a operation vehicles and machines under the influence of alcohol.
