    determining whether speech interference occurs according to a comparison result of an interval between the first time point and the second time point and the time threshold as well as a status corresponding to the first time point;

    filtering out the reference instruction and the current instruction if the speech interference occurs; and

    outputting one of the reference instruction and the current instruction if the speech interference does not occurs.
