Abstract: Embodiments of the present invention provide a spoken language interface to an information database. A plurality of word N-grams from each entry in the information database may be generated. A corresponding probability score for each word N-gram included in the plurality of word N-grams may also be generated. Any one word N-gram from the plurality of word N-grams may be included in a distorted version of the entry generated based on a transformation rule. Duplicate word N-grams from the plurality of word N-grams generated from each entry in the information database may be identified. Corresponding probability scores for the identified duplicate word N-grams may be accumulated. One of the duplicate word N-grams and the corresponding accumulated probability score may be stored in a grammars database.

Abstract: The invention concerns a method and apparatus for processing a user's communication. The invention may include receiving a list of recognized symbol strings of one or more recognized entries. The list of recognized symbol strings may include a first similarity score associated with each recognized entry. From each recognized symbol string one or more contiguous sequences of N-symbols may be extracted. One of the extracted contiguous sequences of N-symbols may be matched with at least one stored contiguous sequence of N-symbols from a first database. A preliminary set of symbol strings and associated second similarity scores may be generated. The preliminary set of symbol strings may include one or more stored symbol strings from a second database that correspond to the at least one matched contiguous sequence of N-symbols. A third similarity score associated with the one or more stored symbol strings included in the preliminary set of symbol strings may be computed.
