Claim 10:
11. The method according to claim 5, wherein in response to determining that the target voice frame is a voiced frame, the parameter set includes a short-term correlation parameter of the target voice frame and a long-term correlation parameter of the target voice frame, and the reconstruction filter includes a long-term predictive (LTP) filter and an LPC filter;
the target voice frame including k daughter frames, the short-term correlation parameter of the target voice frame including an LSF of a kth daughter frame of the target voice frame and an interpolation factor of the target voice frame, and k being an integer greater than 1;
the target voice frame including m subframes, the long-term correlation parameter of the target voice frame including a pitch lag of each subframe of the target voice frame and an LTP coefficient of the each subframe of the target voice frame, and m being a positive integer.
