| 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 |
