A PACKET LOSS RECOVERY TECHNIQUE WITH LINE SPECTRAL FREQUENCY MODIFICATION IN 3GPP EVS CODEC

Abstract: 

This paper examines a method for controlling the energy of decoded signal at the recovery frame from a packet loss. Our observation unveiled that a packet loss around speech onset causes sudden increase in the amplitude of the decoded signal at the recovery frame. To mitigate the artifact caused by the overshoot, a detector of the speech overshoot is proposed as well as a method that controls the amplitude of the decoded signal by adjusting distances of adjacent line spectral frequencies. This technology is implemented in the enhanced voice services (EVS) codec which is the latest speech codec 3GPP standard.
