Patent number: 6122361Abstract: The invention relates to an automated directory assistance system that utilizes a priori advisor for predicting the most likely requested locality. The automated directory assistance system includes a speech recognition dictionary containing a plurality of orthographies, each orthography corresponding to a locality name in which a subscriber whose telephone number is sought by the user of the automated directory assistance system may be residing. Upon reception of the spoken utterance, the system performs a first pass search scores on the basis of acoustics characteristics of the orthographies in the speech recognition dictionary, each orthography having a certain likelihood of being a match to the spoken utterances. The orthographies are then weighed on the basis of information indicative of the geographical location of the user. A final re-scoring operation may then be performed on the top N candidates in the weighed list.Type: GrantFiled: September 12, 1997Date of Patent: September 19, 2000Assignee: Nortel Networks CorporationInventor: Vishwa Gupta

Patent number: 6018708Abstract: The invention relates to a method and an apparatus for recognising speech, more particularly to a speech recognition system and method utilising a speech recognition dictionary supplemented by a lexicon containing frequently occurring word sequences (orthographies). In typical speech recognition systems, the process of speech recognition consists of scanning the vocabulary database or dictionary by using a fast match algorithm to find the top N candidates that potentially match the input speech. In a second pass the N candidates are re-scored using more precise likelihood computations. The novel method comprises the introduction of a step in the search stage that consists of forcing the insertion in the list of N candidates entries selected from a lexicon containing frequently used orthographies to increase the probability of occurrence of certain text combinations.Type: GrantFiled: August 26, 1997Date of Patent: January 25, 2000Assignee: Nortel Networks CorporationInventors: Jean-Guy Dahan, Vishwa Gupta
