A network resource system includes a first server which can communicate with a client computer. The first server produces a speech signal representing speech from a user at the client computer, and context information which indicates the semantic context of the user's speech and a predefined format in which data are returned to the first server. A network knowledge server is in communication with and separated from the first server. The network knowledge server returns to the first server a text structure having one or more fields corresponding to the predefined format. The first server uses data from the one or more fields to determine a response to the user's speech.

A method and apparatus for recognizing an input identifier by comparing a recognized identifier based on the input identifier to a set of reference identifiers maintained in memory. When a match is found between the recognized identifier and one of the reference identifiers, a user is prompted with the matched reference identifier. If the user confirms that the matched reference identifier corresponds to the input identifier, a transaction is executed based on the matched reference identifier. If the user rejects the matched reference identifier, the recognized identifier is compared again to the set of reference identifiers, but for this comparison, the previously rejected reference identifier has been excluded from the set of reference identifiers.

Method and apparatus for performing a grammar-pruning operation

A production script for interactions between participants and an automated data collection system is created by selectively tuning an experimental script through successive trials until a recognition rate of the system is at least an acceptability threshold. The data collection system uses a semi-constrained grammar, which is a practical accommodation of a larger range of possible inputs than a menu. The data collection system collects data by recognizing utterances from participants in accordance with the production script.
