  • Detection of inconsistent training data in a voice recognition system
    Publication number: 20020120446
    Abstract: A method for detecting inconsistent voice training in a speech recognition system includes a first step (202) of inputting data representing a first spoken phrase and a second spoken phrase defining a voice recognition training pair. A next step (206) includes comparing a representation of the training pair with a collection of data of previously stored valid training pairs. A next step (210) includes testing the comparison from the comparing step against a predetermined threshold to determine if the representation of the training pair is consistent. A next step (216) includes storing a combined representation of the training pair as a valid training pair if the training pair is found consistent.
