PROBLEM TO BE SOLVED: To eliminate the ambiguity of modification relation in a syntax analysis by determining the modification relation of the syntax analysis as to each voice section divided with a voiceless section, etc., and recognizing a spoken voice. SOLUTION: A detection part 30 for a voiceless section, etc., detects the voiceless section, etc., including a section based upon a pause, a redundant word, rhythmical information, etc., according to a time series of feature parameters outputted from a buffer memory 3, and outputs its detection signal to an LR purser 5. The LR purser 5 reads in data in the speech section of a section unit indicated with the inputted detection signal and performs a section-limited HMM-LR process using an HMM-LR method for the speech section. Consequently, the modification relation in the speech section of each section unit is determined, and then modification relation between words, phrases, or clauses in the speech sections of different section units is determined. |
