摘要
The present invention defines a new regression function when predicting the subjective sound quality as an objective sound quality evaluation scale in the evaluation of sound quality of a mobile phone system, and uses the defined regression function to calculate an objective sound quality evaluation scale to more accurately predict the subjective sound quality. The present invention relates to a method for predicting subjective sound quality, wherein the present invention performs objective sound quality evaluation and subjective sound quality evaluation on a speech database, and uses the objective sound quality evaluation value and the subjective sound quality evaluation value thus obtained to minimize the subjective sound quality evaluation scale. Regression analysis is performed with a regression function that has the possible and maximum possible values as asymptotes. The objective sound quality is evaluated with respect to the distorted speech, and the objective sound quality evaluation value is substituted into the regression function and the result is output as a subjective sound quality prediction value.
