PCT No. PCT/GB94/00714 Sec. 371 Date Oct. 11, 1995 Sec. 102(e) Date Oct. 11, 1995 PCT Filed Mar. 31, 1994 PCT Pub. No. WO94/23425 PCT Pub. Date Oct. 13, 1994A speech recognition system recognizes connected speech using a plurality of vocabulary nodes, at least one of which has an associated signature. In use, partial recognition paths are examined at decision nodes intermediate the beginning and end of the recognition path, each decision node having an associated set of valid accumulated signatures. A token received by a decision node is only propagated if the accumulated signature of that token is one of those in the set of valid accumulated signatures associated with that decision node.
