Voice voice musical evaluation device, voice mimic voice evaluation method and program

摘要

PROBLEM TO BE SOLVED: To assume whose voice is imitated only by a voice signal to evaluate its similarity.SOLUTION: In a character database storage unit 16, the voice of an object speaker and a related text characterizing the object speaker are stored as a set. A speaker recognition unit 11 calculates a speaker recognition score representing similarity between input voice imitation voice and voice of the object speaker. A voice recognition unit 12 voice-recognizes the voice imitation voice to generate a recognition results text. A text retrieval unit 13 calculates test similarity representing similarity between the recognition results text and a related text. A similarity aggregation unit 14 calculates a voice imitation score aggregating the speaker recognition score and text similarity. An estimation evaluation unit 15 outputs voice imitation evaluation results based on the voice imitation score.SELECTED DRAWING: Figure 1
