PROBLEM TO BE SOLVED: To analyze correspondence on a time base between a plurality of acoustic signals with high accuracy.SOLUTION: An acoustic analysis device 100 includes analysis processing means for specifying, for each of D acoustic signals Ato A, an analysis state series indicating the transition of a plurality of states by using a second left-to-right type Markov model in which are arranged the same number of states as, and in the order common to, a basic state series generated from a first ergodic Markov model capable of transiting between discretionary states and representing a basic structure common to D acoustic signals Ato A. |
