实现MOS语音质量评估，目标文件和样本文件进行比较，并打分。-MOS voice quality assessment

采用阈值法对解调出的信号进行DFT评估，可以最大程度的恢复出原信号，提高了系统的准确性。-Using the threshold method demodulated signal DFT assessment can recover the maximum degree of the original signal to improve the accuracy of the system.

The purpose of this paper is to critically assess current developments in the ory and practice of supply management and through such an assessment to identify barriers, possibilities and key trends.-The purpose of this paper is to critically asse
