Abstract—Speech coding is the act of converting the speech signal in more compressed form, which can be transmittedthrough less number of bits with highest quality. 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. Speech coding is a lossy type of coding and hence the output signal does not exactly sound like the input. Speech coding is useful for long distance communication, message encryption and quality of speech. Speech coding has been major issue in the area of digital speech processing and telecommunication fields.
