Abstract
A speech recognition device which can preferably be used for reducing the memory capacity required for speaker-independent speech recognition is provided. A matching unit loads speech models belonging to a first speech model network and a garbage model in a RAM, and gives a speech parameter extracted by a speech parameter extraction unit to the speech model in the RAM, and when an occurrence probability output from the garbage model is equal to or greater than a predetermined value, the matching unit loads speech models belonging to any of speech model groups in the RAM based on the occurrence probability output from the speech model belonging to the first speech model network.
