Abstract
Various techniques for speech coding and decoding are disclosed. For example, speech data generated from a speech signal may be decoded by receiving the speech data in a format that has at least one main pulse in a subframe of the speech data, and generating a first predicted pulse that has a lower gain than the main pulse. A second predicted pulse may also be generated as a mirror image of the first predicted pulse on a reverse time scale, on the other side of the main pulse in the subframe of the speech data. The the speech signal may be reconstructed using the first predicted pulse and the second predicted pulse.
