Detection Error Tradeoff curves are ROC (receiver operating characteristic) type curves showing the range of operating points of systems performing detection tasks as a threshold is varied to alter the miss and false alarm rates and plotted using a normal deviate scale for each axis. DET curves have the property that if the underlying score distributions for the two types of trials are normal, the curve becomes a straight line. They have been widely used to present the performance characteristics of speaker recognition systems.
