Abstract:
1. A method of decoding speech data in digital form generated from an analog speech signal, the method comprising: receiving the speech data having at least one main pulse in a subframe of the speech data; generating a first predicted pulse, based on the at least one main pulse, on one side of the main pulse in the subframe of the speech data, wherein the first predicted pulse has a lower gain than the main pulse, and wherein the first predicted pulse is at a first distance from the main pulse; generating a second predicted pulse, 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 wherein the second predicted pulse is at a second distance from the main pulse, and wherein the first distance is equal to the second distance; and reconstructing the analog speech signal using the at least one main pulse, the first predicted pulse and the second predicted pulse.
