Abstract
The learning history memory controls, based on the accumulated learning history, the word dictionary memory semantic/syntactic analysis grammar memory and a correction information memory to limit the syntactic/semantic language structure and range of vocabulary, which are not used frequently. Then, the speech recognition collator collates the feature vector with information, having high priority within the limited range, in the word dictionary memory and semantic/syntactic analysis grammar memory to recognize the speech.
