Abstract
A speech recognition system and method having an increased recognition accuracy for a compound word composed of a first word and a second word. Standard information corresponding to each of the registered words is stored. The standard information includes predetermined feature information and time information with respect to each of the registered words. The time information represents a continuous time length for pronouncing each of the registered words at a normal speed. Feature information extracted from an input word is compared with the standard information to obtain a similarity between the feature information and the standard information corresponding to one of the registered words. A determination time is set to determine a result of recognition when the compound word is input and when a first degree of similarity is obtained from the first word at a first time and a maximum degree of similarity is obtained from one of the second word and the compound word at a second time. The determination time is set to a time prior to the second time, by the continuous time length which corresponds to the one of the second word and the compound word having the maximum degree of similarity.
