Claim One:
1. In a continuous speech recognition system comprising an input pattern buffer memory for temporarily memorizing an input pattern A represented by a time sequence of input pattern feature vectors a.sub.i, I in number, as: EQU A = a.sub.1, a.sub.2,. .. , a.sub.i,. .. , a.sub.I, said input pattern being representative of a first predetermined number k of continuously spoken words, said first predetermined number being equal at least to unity; a reference pattern memory for memorizing reference patterns B.sup.n representative of a second predetermined number of words n, each reference pattern being represented by a time sequence of referene pattern feature vectors b.sub.j.sup.n, J.sup.n in number, as: EQU B.sup.n = b.sub.1.sup.n, b.sub.2.sup.n,. .. , b.sub.j.sup.n,. .. , b.sub.J.spsb.n.sup.n : and means responsive to said input and reference pattern feature vectors for recognizing said input pattern to be a concatenation of the reference patterns, k in number; the improvment wherein said means comprises a word number specifier for specifying the number K of words of said input pattern, said word number K being preselected for a predetermined duration to be equal at least to unity with reference to said first predetermined number; and recognition means responsive to said word number K and said input and reference pattern feature vectors for deciding said concatenation.
