摘要

PROBLEM TO BE SOLVED: To obtain a language model having high estimation precision and a voice recognition device having high recoginition precision.;SOLUTION: A learning text data tree structure clustering means 2001 conducts a tree structure clustering to hierarchically divide learning text data 1001 so as to have a linguistically similar nature and generates a tree structure learning text data cluster 2002. A language model generating means 1004 generates a tree structure cluster language model 2003 employing each learning text data which belongs to the cluster 2002.;COPYRIGHT: (C)2002,JPO
