“…• Accuracy, recall, precision, and specificity: to test the efficiency of a suggested method in ASR field, the classification accuracy, recall (sensitivity) or commonly known as true positive rate (TPR), precision (known also as positive predictive value), and specificity (commonly known as true negative rate (TNR)) are often used as assessment criteria for experiment results, such as in [56,30,57]. The accuracy rate is defined as the proportion of properly assessed samples to the total number of samples.…”
