This paper proposes a novel approach that a system which enhances the speech signals, encodes it using bit rate. The noisy speech signals are being enhanced through speech enhancer , which is obtained by using code excited linear prediction [CELP]. This provides good scalability and reliability. Further the encoded speech gets compress voice signal using a lossy compression technique called linear predictive coding (LPC) vocoder, this is again the system of encoding speech at a low bit rate. To create an excitement signals in the decoder, the encoder sends voicedunvoiced information, and the pitch period for voiced segment which is used. Now, the encoded gets decoded and the signal is reconstructed. The performance of the system is attained by the reconstructed speech. This inference is carried out and performance shows increase in lucidity of the reconstructed signal. The reconstructed signal evidences the efficiency of the project.
