Abstract

The system and method are used for recognising a time-sequential input pattern (20), which is derived from a continual physical quantity, such as speech. The system comprises input means (30), which accesses the physical quantity and therefrom generates a plurality of input observation vectors. The input observation vectors represent the input pattern. A reference pattern database (40) is used for storing a plurality of reference patterns. Each reference pattern consists of a sequence of reference units, where each reference unit is represented by at least one associated reference vector νa in a set {νa} of reference vectors. A localizer (50) is used for locating among the reference patterns stored in the reference pattern database (40) a recognised reference pattern, which corresponds to the input pattern.
