<p>In relation to the spectrum of the original signal transmitted by the calling telephone, the voice signal on a telephone channel, received by the receiving telephone, is subjected to a processing procedure which evaluates the composition of the frequency spectrum of the received signal and subjects it to an equalization process comprising the determination of the selective attenuation of some frequencies and the selective amplification of others, on the basis of the deformations/distortions of the signal by the transmission channel. The embodiment allows adjusting and filtering the dynamically amplified frequencies in real time, through a dedicated menu on the cell phone display. A simultaneous conversion of the speech into text is provided for greater comprehensibility.</p> |
