MORPHEME ANALYSIS DEVICE, METHOD AND PROGRAM THEREFOR, VOICE SYNTHESIS DEVICE, AND METHOD AND PROGRAM THEREFOR

PROBLEM TO BE SOLVED: To improve analysis accuracy in reading combination of words to be nominals (common nominals, proper nominals, prefixes, suffixes or the like) adjacent to each other in a text to be analyzed and are registered separately in a word dictionary.SOLUTION: In a first word dictionary 18, words which are selected in consideration of accuracy of morphological analysis are registered, and in a second word dictionary 20, words unregistered in the first word dictionary 18 are additionally registered. A word linking possibility determination section 16 registers combination of words which are nominals existing in a text included in a learning text corpus 34 while having a specific word such as a Japanese particle "no" interposed in between, and one of which is registered in the second word dictionary 20, in a word linking possibility table 24, and calculates and registers a deduction value with respect to another combination of nominals of which words registered in the first word dictionary 18 are different from the combination of nominals. In the morphological analysis of an analysis object text 32, a morphological analysis section 14 subtracts the deduction value from a link evaluation value of a combination of words being nominals adjacent to each other in the analysis object text 32, one of which is registered in the second word dictionary 20 and is not registered in the word linking possibility table 24.
