PiD, a person identification system using voice and face
USA Patent 5,412,738
The strategy used by the described system is based on Vector
Quantization ( see the paper Person
Recognition Using Multiple Cues,R. Brunelli and D. Falavigna).
The acoustic vectors are compared with the codebooks of the reference
speakers. The comparisons consists in the evaluation of a distance
between input vectors and codebooks. The obtained distances (one for
each reference user) are sent to the integration module.
