Abstract:
1. A method, comprising: encoding via at least one stage of a transceiver, said encoding being performed to encode a frame using at least one of a plurality of codec modes, wherein an encoded frame formed by at least one of said codec modes comprises a plurality of parameters, wherein said at least one stage comprises: first, calculating values for said plurality of parameters of the encoded frame; second, selecting one group of codec modes from a plurality of groups of codec modes using said calculated values of said parameters, wherein each of said groups of codec modes comprises at least one speech processing algorithm and comprises a common parameter characteristic, wherein the selection is performed according to at least one of prior to calculating a linear prediction coding operation, after calculating a linear prediction coding operation and prior to calculating a long term prediction operation, and after calculating a linear prediction coding operation and a long term prediction operation; and third, encoding the frame with at least one of the speech processing algorithms from the selected group of codec modes in dependence on said common parameter characteristic.
