Summary:Selecting the high-band spectral envelope prediction technique and high-band excitation synthesis scheme to produce the synthesized high-band signal. Extension of narrow-band speech is a scheme that adds a synthesized high-band signal to narrow-band speech to produce a higher quality wide-band speech.
