| Abstract: | The communication of speech has the characteristics of a large amount of voice data in the VoIP (Voice over IP ). We study a variety of speech coding scheme. At the same time, we test the speech compression rate, coding rate and MOS(Mean Opinion Score) in the VoIP system. In result, the audio coding scheme of Speex(a kind of the audio compression coding format based on code excitation linear predictive coding), in the case of considering many factors , has a comparative advantage. |
