Abstract  Abstract

A wideband speech encoder according to one embodiment includes a narrowband encoder and a highband encoder. The narrowband encoder is configured to encode a narrowband portion of the wideband speech signal into a set of filter parameters and a corresponding encoded excitation signal. The high band encoder is configured to encode the high band portion of the wideband speech signal into a set of filter parameters according to the high band excitation signal. The high-band encoder generates a high-band excitation signal by applying a nonlinear function to a signal based on the encoded narrow-band excitation signal, thereby generating a spectrum extension signal.
