This software recognizes the isolate digits. It is possible to recognize digits 0-9. Particular digits’ templates are stored in folder “wav”. It is possible to change or extend these templates which is recommended especially in case the user is about to change a microphone (there can be problems with a channel distortion). To recognize the digit and to calculate a distance between template and unknown signal there was used algorithm of dynamic time warping. This software can be used to develop or test the classifiers, speech features or it can be used for education in the field of pattern recognition.
