In this paper, we summary the issues met during the high quality speech transmission in the wireless network, compare with current packet loss recovery technology, and highlight the introduction of the efficient packet loss recovery algorithm aimed at the low bandwidth, fluctuation, and high error code of the wireless network. At the same time, combined with AMB-WB, put forward the adaptive transmission mechanism, and then further improve the anti-packet loss ability and packet loss recovery to reach the aim of transmitting the high quality real-time speech in wireless network. Via the experiment and analysis, the algorithm mentioned in this paper reaches the great results in speech quality improvement.
