ABSTRACT:
A voice transfer system for transferring a voice data signal extracts and regenerates frequency components from an original voice signal converted into digital voice data. In a voice transmitter, a plurality of frequency transformation units successively extract frequency components in stepwisely increasing frequency ranges from the converted voice signal and remove the frequency component from the signal supplied to the next frequency transformation unit. The frequency components are received by a voice receiver which reverse transforms each component and sums them to reconstruct a voice signal which differs from the original voice signal by a reduced error component.
