To provide a model evaluation method, a model evaluation device, an electronic equipment, a computer-readable recording medium, and a computer program product improving evaluation efficiency for a personalized voice synthesis model.SOLUTION: A model evaluation method: acquires M number of first audio signals synthesized by a first evaluation subject voice synthesis model and recorded N number of second audio signals; acquires M number of first voice print characteristics by carrying out voice print extraction to each of the M number of first audio signals; acquires N number of second voice print characteristics by carrying out voice print extraction to each of N number of second audio signals; acquires K number of first central characteristics by clustering the M number of first voice print characteristics; acquires J number of second central characteristics by clustering the N number of second voice print characteristics; acquires a first distance by calculating statics of a cosine distance between K number of first central characteristics and J number of second central characteristics; and evaluates the first evaluation subject voice synthesis model based on the first distance.SELECTED DRAWING: Figure 1
