A voice service quality assessment methods and apparatus

The present invention discloses a method for voice quality assessment methods and apparatus, the method comprising: obtaining network performance parameters; the network performance parameters of the signal pre-processing parameters to obtain an array Pre_data; an array of the principal component Pre_data extract, obtained PCA_data array, and the array contains the main ingredient within PCA_data parameters for voice quality assessment of the contribution exceeds a preset threshold and unrelated; using the array PCA_data get voice service quality evaluations. Embodiments of the invention, the network operators can obtain performance parameters based on a more rational data preprocessing methods to ensure the accuracy of the prediction voice quality; by extracting principal component parameters independently of each other to give a greater contribution and are not mutually parameters related to the elimination of the correlation between parameters, such that a more accurate assessment.
