Abstract
Communications equipment should be able work at low bit rate, that can reduce the need for transmission bandwidth. The proposed speech coder generates coded signal at the rate of 4 kbps with low complexity. Thus, the transmission channel can be used for great number of communications connection. The low bit rate speech coder can be realized by using segmental sinusoidal model. By using this model, signal parameters are used to generate the synthetic speech signal.. In this paper, we proposed a sinusoidal model by using the peak of signal amplitude, called as segmental sinusoidal model. The proposed coder is combined with waveform interpolation model and codebook, thus it can work at low bit rate. The coder has MOS score of 3.8 (out of 5). It means that the perception quality is fairly good. The output data rate of encoder is 4 kbps or bellow, with complexity less than IO MIPS(Million Instruction per Second).
