Interpreting the need of high quality wideband speech coding some standardization events have been conducted. There are various methods and standard for speech coding. these paper present a new technique of speech coding. here interpretation is done with the help of gamma tone filter bank. The o/p of the system is analyzed and process to get the respective train of pulses. the positioning and amplitude and gain of pulses are coded using the process of quantization.
