| Abstract: | :A new speech code system which contains various algorithms and works at many different bit rates has been designed in this paper.Synthesized speech qualities have been improved by using LPC intra frame interpolator at low bit rates.Layered encoder and system with variable bit rates by using SAD technique have also been involved to fit the needs of ATM networks in the future. |
| Keywords: | :Signal Processing Speech Coding |
