Speech coding is an algorithm used to analyze the special, non- stationary and intelligent speech signal in order to extract its important parameters and to compress it for the maximum utilization of available bandwidth. To achieve this, various speech coding algorithms have been effectively used. Out all these algorithms, Linear Predictive Coding (LPC) is the most powerful one as it provides accurate estimation of speech parameters and is computationally effective and used to represent the speech signal at reduced bit rates while preserving the quality of the signal. Voice- excited LPC is the algorithm proposed in this paper. This algorithm has been implemented using Hindi and English male and female voices and trade- offs between bit rates, delay, power signal to noise ratio and complexity are analyzed. It results in low bit-rates and better signal to noise ratio.
