Big changes in both narrowband and wideband. Retrained LSP codebook,
replaced pseudo-multi-pulse by split codebook (no gain) for narrowband.
Changed gain-shape approach to gain-only split-VQ for wideband. Wideband
bit-rate goes down (31.3 kbps to 26.9 kbps). Narrowband is about the same
(now 15.1 kbps).
