Speaker Verification.
Abstract
A practical method of automatic speaker verification is developed, based on amplitude spectrum. Precise time registration receives primary emphasis. Verification is based on the similarity of six spectral/time matrices located with a test phrase with corresponding matrices defined during training. Each matrix is 0.1 second long and is precisely located by scanning the test phrase for a best match with the reference matrix. Reject rate for known speakers was plotted versus session number, at a nominal reject rate of 10 percent. Initial and final reject rates of 5 percent and 15 percent, respectively, indicate the necessity of adaptation in a practical system. (Modified author abstract)
