Patent number: 9330660Abstract: A method and apparatus are provided for automatically acquiring grammar fragments for recognizing and understanding fluently spoken language. Grammar fragments representing a set of syntactically and semantically similar phrases may be generated using three probability distributions: of succeeding words, of preceding words, and of associated call-types. The similarity between phrases may be measured by applying Kullback-Leibler distance to these tree probability distributions. Phrases being close in all three distances may be clustered into a grammar fragment.Type: GrantFiled: March 4, 2014Date of Patent: May 3, 2016Assignees: AT&T Intellectual Property II, L.P., Nippon Telegraph & TelephoneInventors: Kazuhiro Arai, Allen L.
