Efficient Acoustic Front-End Processing for Tamil Speech Recognition using Modified GFCC Features

Reduce common energy loss in transmission.

In order to achieve the above quality of an input signal, the amplitude adjustment technique has been executed. The amplification is applied to set the maximum volume required for the given signal. It is calculated and adjusted automatically without clipping. In this research work, an amplification level is set to 2.7dB. Both amplification and equalization techniques help to reduce within word variation.
