  • Patent number: 9943260
    Abstract: 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.

  • Patent number: 9916845
    Abstract: This method for determining alcohol use comprises the steps of: detecting an effective frame in an input audio signal; detecting a difference in signal within the original signal of the effective frame; performing a fast Fourier conversion on the difference signal to be transformed into a frequency domain; detecting high-frequency components within the difference signal subjected to the fast Fourier transform; and determining the state of alcohol use on the basis of a gradient difference between the high-frequency components. Accordingly, the present invention can identify the state and extent of alcohol use by a driver or an operator from a long distance and thus can prevent accidents caused by driving or operating vehicles and machines under the influence of alcohol.
