Provided are a voice analysis apparatus, a voice analysis method, and a program that enable a steady tendency of a beat cycle to be specified with high accuracy. A sound volume correlation value calculation section (48) calculates, for each of a plurality of time intervals, a value indicating a degree of correlation in a sound volume of voices at two or more timings separated by the time interval, as a sound volume correlation value associated with the time interval. A beat cycle specification section (50) specifies the beat cycle of the voices on the basis of the sound volume correlation value associated with each of the plurality of time intervals.
