Patent number: 10839789Abstract: An acoustic coprocessor is provided. The acoustic coprocessor may include an interface for receiving at least one feature vector and a calculating apparatus for calculating distances indicating the similarity between the at least one feature vector and at least one acoustic state of an acoustic model read from an acoustic model memory. The acoustic coprocessor may also include an interface for sending at least one distance calculated by the calculating apparatus.Type: GrantFiled: August 8, 2018Date of Patent: November 17, 2020Assignee: Zentian LimitedInventors: Guy Larri, Mark Catchpole, Damian Kelly Harris-Dowsett, Timothy Brian Reynolds

Patent number: 9425826Abstract: A method of generating an interleaved symbol sequence location from a symbol location of a symbol sequence comprises determining the interleaved symbol location based on an interleaver sequence function which relates a linear symbol location to the interleaved symbol location. This is done by acquiring values of the interleaver sequence function in quotient and remainder form and then calculating the interleaved symbol location by performing operations of the interleaver sequence function in quotient and remainder form.Type: GrantFiled: November 2, 2012Date of Patent: August 23, 2016Assignee: BlackBerry LimitedInventor: Damian Kelly Harris-Dowsett
