Abstract:
A method for reconstructing an erased speech frame is described. A second speech frame is received from a buffer. The index position of the second speech frame is greater than the index position of the erased speech frame. The type of packet loss concealment (PLC) method to use is determined based on one or both of the second speech frame and a third speech frame. The index position of the third speech frame is less than the index position of the erased speech frame. The erased speech frame is reconstructed from one or both of the second speech frame and the third speech frame.
