Title: An improved rcelp coder
Inventor: KLEIJN WILLEM BASTIAAN
IPC: G10L19/00
Filed: 1996-08-14
Abstract: An improved method of speech coding for use in conjunction with speech coding methods wherein speech is digitized into a plurality of temporally defined frames, each frame including a plurality of sub-frames, and the digitized speech is partitioned into periodic components and a residual signal. For each of a plurality of sub-frames of the residual signal, the improved method of speech coding selects and applies a time shift T to the sub-frame by applying a matching criterion to (a) the current sub-frame of the residual signal, and (b) a sample-to-sample (sub-frame-to-subframe) pitch delay determined by applying linear interpolation to known pitch delays occurring at or near frame-to-frame boundaries of previous frames. The matching criterion is applied by minimizing .epsilon., where:               .epsilon. = .SIGMA.(r(n-T)-r(n-D(n)))2.     n (r(n-T)) is the residual signal of the current frame shifted by time T, r(n-D(n)) is the delayed residual signal from a previously-occurring frame, n is a positive integer, r is the instantaneous amplitude of the residual signal, and D(n) is the sample-to-sample pitch delay determined by applying linear interpolation to known pitch delay values occurring at or near frame-to-frame boundaries.
