Abstract
This paper presents a new speech coding technique for near toll-quality performance at around 4800 bps. Currently, the most promising techniques at these bit rates emphasize the efficient coding of residual information in a Linear Predictive Coding context. The Multipulse Linear Predictive Coder (MPLPC) [1] and the Code Excited Linear Predictive Coder (CELPC) [2] are examples where considerable success has been achieved at medium bit rates. This paper introduces the Self Excited Vocoder (SEV), a new speech coding technique which belongs to the same class of coders as the MPLPC and the CELPC.Keywords
