Patent CA-2223471-A1 (CA)
Inventor: ELMALEH DAVID R
IPC: A61B19/00
Filed: 1996-06-07
Abstract: A method for controlling the spread of HIV/AIDS and other infectious diseases.  Individuals desirous of reducing the risks of infection and preventing the spread of such diseases voluntarily participate in a testing program whereby regular periodic screening tests are performed to indicate the infection status of each such individual for any of several infectious diseases. The infection status information is coded for each individual and is stored in a confidential database. An individual can access his infection status information upon making an inquiry using a unique personal identification number, or PIN. The individual's identification information is matched with his infection status information in the database and provides that information immediately either orally or in written form. Two participating members of the program can obtain their infection status data jointly, thereby providing reliable, current infection status information to each other contemporaneously while avoiding the risks of nondisclosure or misrepresentation of such information by one or both parties.

IPC: G10L15/06
Filed: 1998-01-26
Abstract: Frequency warping approaches to speaker normalization have been proposed and evaluated on various speech recognition tasks.  In all cases, frequency warping was found to significantly improve recognition performance by reducing the mismatch between test utterances presented to the recognizer and the speaker independent HMM model.  This invention relates to a procedure which compensates utterances by simultaneously scaling the frequency axis and reshaping the spectral energy contour.  This procedure is shown to reduce the error rate in a telephone based connected digit recognition task by 30%.
