Sr RELP VELP
1 Residual Excited Linear Prediction (RELP) based vocoder Voice Excited Linear Prediction (VELP) based vocoder
2 enter image description here enter image description here
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
