Patent number: 7953594Abstract: A method and an apparatus for selecting a vocabulary closest to an input speech from among lexicons stored in memory, wherein a centroid lexicon representing lexicons belonging to a predetermined lexicon group is generated. Two lexicons, having a longest distance therebetween in the lexicon group, are selected using the centroid lexicon from the lexicon group, and a node indicating the lexicon group branches based on the two selected lexicons. A node having low group similarity is selected from among current terminal nodes, including branch nodes, and the above procedure is repeatedly performed on a lexicon group indicated by the selected node.Type: GrantFiled: January 31, 2006Date of Patent: May 31, 2011Assignee: Samsung Electronics Co., Ltd.Inventors: Sang-bae Jeong, In-jeong Choi, Ick-sang Han, Jeong-su Kim
