File Information

The digit recognition code plots the accumulated distance along the best alignment path for each of the 11 reference pattern matches with the test pattern, and chooses the reference pattern with the smallest accumulated distance as the recognized word.
The isolated digit speech recognizer uses a training/testing set of 5 occurrences of each of 11 spoken digits (spoken by a single talker as isolated digits), consisting of the set of isolated digits from 0-9 plus the word ’oh’. Each digit file was carefully hand-endpointed so that the remaining signal was the speech without any background noise or acoustic artifacts.
