Abstract
An electrical voice print is converted into sampled digital values which are converted into corresponding moment invariants (MI). A comparison of the moment invariant values of a standard phrase uttered by the same person and stored in the storage means against the most recently converted moment invariants determines the degree of correlation. A high degree of correlation is indicative of a voice match.
