Run step1, step2, step3 and step4 under HTKSimpleDemo:

(take a copy, using the corresponding zip-file).

step1:  Feature-extraction (HCopy)
step2:  Whole-word Reestimation (Training) (HRest)
step3:  Recognition (HVite)
step4:  Evaluation (HResults)


The vocabulary consists of the five Danish words: 0, 1, 2, 3, 4

The result of step4 should be:
