Abstract

A method for identifying any one of a plurality of utterances using a programmed digital computing system, each utterance having an audible form representable by a sequence of speech elements each having a respective position in the sequence. In the computing system, a digital representation corresponding to each of the plurality of utterances is stored a designation respective identifying is assigned to each utterance. A table composed of a plurality of entries is created, each entry being associated with a unique combination of a particular speech element and a particular position in the sequence of speech elements of the audible form of an utterance and storing in each entry the identifying designation of each of the plurality of utterances whose audible form is represented by a speech element sequence containing the particular speech element at the particular position with which that entry is associated; converting an utterance to be identified and spoken by a person into a sequence of speech elements each having a respective position in the sequence; reading each table entry associated with a speech element and position combination corresponding to the combination of a respective position in the sequence of the spoken utterance and the particular speech element at the respective position in the sequence of the spoken utterance; and determining which identifying designation appears most frequently in the entries which have been read in the reading step.
