Acoustic quality evaluation device, sound quality evaluation method, and program

摘要

PROBLEM TO BE SOLVED: To estimate a MOS value from a PESQ value performing a little amount of calculation.SOLUTION: An acoustic quality evaluation device: obtains a first PESQ value for a first reference acoustic signal and a first evaluation object acoustic signal based on a signal including the first reference acoustic signal; and obtains a first MOS value by linearly converting the first PESQ value on the basis of linear relation between a second PESQ value corresponding to a second reference acoustic signal and a second evaluation object acoustic signal based on a signal including the second reference acoustic signal, and a second MOS value based on five-stage evaluation about the difference between reference sound corresponding to the second reference acoustic signal and evaluation sound corresponding to the second evaluation object acoustic signal.SELECTED DRAWING: Figure 13
