Abstract
The voice analysis device includes: a voice information acquiring unit that acquires a voice signal generated by plural voice acquiring units disposed at different distances from a speaking section of a speaker and acquiring voice of the speaker; and an identification unit that identifies the speaker corresponding to the voice having been acquired, on the basis of intensities of respective peaks in a frequency spectrum of a first enhanced waveform and a frequency spectrum of a second enhanced waveform. The first enhanced waveform is a waveform where a voice signal of a predetermined target speaker has been enhanced, and the second enhanced waveform is a waveform where a voice signal of a speaker other than the target speaker has been enhanced.
