摘要：
An alcohol consumption determination method includes: detecting an effective frame of an input voice signal； detecting a difference signal of an original signal of the effective frame； performing fast Fourier conversion on the original signal and the difference signal； and determining, in the frequency domain, whether alcohol has been consumed based on a slope difference between the fast-Fourier-transformed original signal and the fast-Fourier-transformed difference signal. Accordingly, it is also possible to determine whether a driver or an operator from a remote location has consumed alcohol and a degree of the consumption, thus preventing an accident caused by an individual operating a vehicle under the influence.
