Disclosed is a method for drastically reducing the average error rate for signals under mismatched conditions. The method takes a signal (e.g, speech signal) and a set of stored representations (e.g, stored representations of keyword) and performs at least one transformation that results in the signal more closely emulating the stored representations. This is accomplished by using one of three techniques. First, one may transform the signal so that the signal may be better approximated by (e.g, is closer to) one of the stored representations. Second, one may transform the set of stored representations so that one of the stored representations better approximates the signal. Third, one may transform both the signal and the set of stored representations.
