Sr	RELP	VELP
1	Residual Excited Linear Prediction (RELP) based vocoder	Voice Excited Linear Prediction (VELP) based vocoder
2
3	The LPC are chosen so as to minimize the prediction error. The error signal approximately represents the excitation signal	In this scheme, LPC analysis is performed on the received signal to create a new error signal
4	Error indirectly used	Error directly used excitation
5	High pass vocoder is not used	The low-pass filtered speech is added to a high pass vocoder speech to get the synthesized speech
