Abstract
A speech recognition method implemented in a computer system recognizes words without requiring prior creation of models for such words based on spoken entries. A key word is entered in nonspoken form and a string of phonemes are defined by the speech recognizer to represent the new key word. A response signal is generated from each phoneme in the new key word model. Such response signals are utilized to define a multidimensional validity field for the new key word. Upon receipt of a spoken word from a user, a string of phonemes is assigned to represent the spoken word. A response signal from each phoneme in the model used to represent the spoken word is contrasted with the validity fields previously defined for the corresponding key word. A determination is made as to whether the spoken word is valid or not based on whether the response signals representing the spoken word lie within the validity fields.
