Question: In the context of Enhanced Voice Services (EVS) decoding, what is the primary purpose of decoding the parameters described in the error concealment procedure?
Option 1: To enhance voice quality by boosting signal energy
Option 2: To aid in the frame erasure concealment process for maintaining voice continuity
Option 3: To adjust the spectral envelope for noise reduction
Option 4: To synchronize phase control with the receiver's clock
Explanation: The primary purpose of decoding these parameters is to assist in concealing frame erasures, maintaining voice continuity and quality when errors occur during transmission, a key aspect of Enhanced Voice Services (EVS) in telecommunications.
