Abstract: An example method includes: receiving a test phrase; comparing feature vectors of the test phrase to contents of a first database to generate a first score; comparing the feature vectors of the test phrase to contents of a second database to generate a second score; comparing feature vectors of the contents of the second database to the contents of the first database to generate a third score; comparing the feature vectors of the contents of the second database to a model of the test phrase to generate a fourth score; determining a first difference score based on a difference between the first and second scores; determining a second difference score based on a difference between the third and fourth scores; and generating a difference confidence score based on a lesser of the first and second difference scores.

Abstract: A method of encoding samples in a digital signal is provided that includes receiving a frame of N samples of the digital signal, determining L possible distinct data values in the N samples, determining a reference data value in the L possible distinct data values and a coding order of L−1 remaining possible distinct data values, wherein each of the L−1 remaining possible distinct data values is mapped to a position in the coding order, decomposing the N samples into L−1 coding vectors based on the coding order, wherein each coding vector identifies the locations of one of the L−1 remaining possible distinct data values in the N samples, and encoding the L−1 coding vectors.
