Abstract  Abstract

A wideband speech encoding apparatus and a method for encoding/decoding speech is disclosed. The wideband speech encoder apparatus includes a lowband encoder and a highband encoder. The highband encoder is configured to calculate values for coding parameters that specify a spectral envelope an extended signal and a gain envelope. The gain envelope is based on the relation between the highband and lowband portions.
