Parameter prediction device and parameter prediction method for acoustic signal processing

摘要

PROBLEM TO BE SOLVED: To provide a parameter prediction device that, in optimization of a control parameter set for acoustic signal processing, is capable of: improving the accuracy of prediction of a control parameter set; and reducing a load or a time related to the optimization.SOLUTION: A parameter prediction device 100 that predicts a control parameter set for controlling acoustic signal processing includes: an environmental characteristic acquirer 101 that acquires an environmental characteristic quantity set which quantifies one or more characteristics of a sound collection environment for an acoustic signal; a target setter 102 that sets a target evaluation value set which provides one or more values obtained by quantifying one or more performances of the acoustic signal processing, or one or more evaluation values of a processed acoustic signal; and a first predictor 103 that inputs the environmental characteristic quantity set and the target evaluation value set as independent variables to a first prediction model, and predicts a control parameter set.SELECTED DRAWING: Figure 2
