Increasing number of mobile subscribers along with plethora of bandwidth intensive applications has energized the researchers to look at the early instances of capacity exhaustion. As a consequence, the optimum utilization of bandwidth and power consumed by the mobile handset has evolved to be a critical issue for research. The talk time and recharging of mobile handset has been adversely affected due to these bandwidth intensive applications including internet through mobile. Several techniques in voice/speech communication have already been analyzed for channel utilization enhancement but some important issues like freeze out of speech, delay, speech hangover, deterioration of speech and inter-modulation gap problems remained unresolved.
