Apparatus and a corresponding method for processing speech signals in a noisy reverberant environment, such as an automobile. An array of microphones () receives speech signals from a relatively fixed source () and noise signals from multiple sources () reverberated over multiple paths. One of the microphones is designated a reference microphone and the processing system includes adaptive frequency impulse response (FIR) filters () enabled by speech detection circuitry () and coupled to the other microphones to align their output signals with the reference microphone output signal. The filtered signals are then combined in a summation circuit (). Signal components derived from the speech signal combine coherently in the summation circuit, while noise signal components combine incoherently, resulting in composite output signal with an improved signal-to-noise ratio. The composite output signal is further processed in a speech conditioning circuit () to reduce the effects of reverberation.

Method and apparatus for providing a standardized measure of accuracy of each biometric device in a biometric identity authentication system having multiple users. A statistical database includes continually updated values of false acceptance rate and false rejection rate for each combination of user, biometric device and biometric device comparison score. False acceptance rate data are accumulated each time a user successfully accesses the system, by comparing the user's currently obtained biometric data with stored templates of all other users of the same device. Each user is treated as an &ldquo;impostor&rdquo; with respect to the other users, and the probability of an impostor's obtaining each possible comparison score is computed with accumulated data each time a successful access is made to the system. The statistical database also contains a false rejection rate, accumulated during a test phase, for each combination of user, biometric device and biometric device comparison score.
