PROBLEM TO BE SOLVED: To perform voice evaluation that a user highly satisfies by a more diverse evaluation method than usual using data recorded on a CD for music etc., put on the market.SOLUTION: A voice evaluation device (10) comprises an evaluation object pitch extraction part (11), a reference pitch extraction part (12), and an evaluation part (20). The evaluation object pitch extraction part (11) extracts the pitch of a voice of voice data as an evaluation object pitch along a time axis. The reference pitch extraction part (12) extracts pitches of a plurality of sounds as reference pitches from audio data including the plurality of sounds along the time axis. The evaluation part (20) evaluates the voice data by comparing the evaluation object pitch with the plurality of reference pitches at each unit time along the time axis.SELECTED DRAWING: Figure 1 |
