Publication number: 20140303978Abstract: 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: ApplicationFiled: March 4, 2014Publication date: October 9, 2014Applicant: AT&T INTELLECTUAL PROPERTY I, L.P.Inventors: Kazuhiro Arai, Allen L.

Patent number: 8684531Abstract: An image signal storing unit stores an image signal provided from the outside. An image processing unit appropriately processes the image signal stored in the image signal storing unit in accordance with the instruction from an adjusting unit. A projecting unit projects, onto a display area, light corresponding to an image created by the image processing unit. A display size determination unit computes the display size of the picture plane displayed on a screen based on an image captured by the camera provided adjacent to the projection-type video-image display device. The display size determination unit then determines whether or not the display size of the picture plane is equal to or larger than a predetermined upper-limit size.Type: GrantFiled: December 28, 2010Date of Patent: April 1, 2014Assignee: Vision3D Technologies, LLCInventors: Ken Mashitani, Masutaka Inoue, Hideyuki Kanayama, Takashi Ikeda, Takahisa Ando, Kazuhiro Arai, Ryuhei Amano
