Title of the Invention AUTOMATIC SPEAKER VERIFICATION SYSTEMS EMPLOYING MOMENT INVARIANTS Abstract of the Disclosure In one preferred embodiment of the present invention there is provided a means for converting an electrical voice print into sampled digital values and a means for converting the sampled digital values into corresponding moment invariants. Storage means are provided for storing prior obtained moment invariants of the standard phrase uttered by the same person. A comparison means compares the moment invariant values stored in the storage means against the most recently converted moment invariants to determine the degree of correla- tion. A high degree of correlation is indicative of a voice match.
