Patent number: 5751898Abstract: Speech recognition is achieved using a normalized cumulative distance. A normalized Dynamic Programming (DP) value is calculated by dividing a cumulative path distance by an optimal integral path length. The path length is calculated iteratively by adding 2 if the warping path is diagonal or by adding 3 if the warping path is horizontal or vertical. Distance may be calculated by measuring a difference between input power and average power. The power difference is weighted by a coefficient (.lambda.) between 0 and 1. A Mahalanobis distance is then weighted by (1-.lambda.) and added to the weighted power difference.Type: GrantFiled: February 22, 1994Date of Patent: May 12, 1998Assignee: Canon Kabushiki KaishaInventors: Tetsuo Kosaka, Atsushi Sakurai, Junichi Tamura

Patent number: 5621849Abstract: A voice recognizing method apparatus in which an input voice is recognized by obtaining a similar pattern by comparing the input voice and voice standard patterns. Voice standard patterns are stored into a memory. A voice is inputted. Voice duration lengths and distances are calculated by performing matching processes between the input voice and the standard patterns. The distance is corrected in accordance with the voice duration length so that the voice duration length having the best matching result is used as a reference, or such that the distance is small as the voice duration length is long. A recognition result is determined in accordance with the corrected distance. The matching is executed by a word spotting method. The input voice to be matched and the voice standard patterns are expressed by voice characteristic parameters.Type: GrantFiled: January 11, 1995Date of Patent: April 15, 1997Assignee: Canon Kabushiki KaishaInventors: Atsushi Sakurai, Junichi Tamura, Tetsuo Kosaka, Hiroshi Matsuo

Patent number: 5019907Abstract: Horizontal synchronizing signals included in a video signal are inputted to a PLL circuit. A counter as a divider in the PLL circuit outputs signals which are synchronized with the horizontal synchronizing signals. A gate pulse generator counts the output pulses of counter and produces a control signal for controlling a phase comparator as one of elements of the PLL circuit. The operation of phase comparator is stopped in vertical intervals in accordance with the control signal so that the phase comparator is not affected by signals which are included in the video signal and are not synchronized with the horizontal synchronizing signals. Thus, the PLL circuit produces pulses which are synchronized with the horizontal synchronizing signals in a wide frequency range.Type: GrantFiled: December 5, 1989Date of Patent: May 28, 1991Assignee: Kabushiki Kaisha Yamashita Denshi SekkeiInventors: Satoshi Murakoshi, Atsushi Sakurai
