    In the paper a voice transformation approach based on the application of the Pitch Synchronous OverLap and Add /PSOLA/ principle and resampling is proposed. This algorithm has lower computational demands than frequency domain methods.

    V příspěvku je navržena transformace hlasu založená na použití metody Pitch Synchronous OverLap and Add /PSOLA/ a na převzorkování. Algoritmus má nižší výpočetní nároky než metody pracující v kmitočtové oblasti.
