The results of SFF measurements of well-known Polish personalities and their imitations performed by cabaret entertainers are presented and discussed. The difference in F0 between the original speakers and their imitators was in some cases few Hz only, but in some other cases it reached more than 10...

This paper investigates the possibility of using long-term analysis of the zero-crossings of a speech signal for speaker identification. The applied method of identification is based on an analysis of the signal in measuring windows of a duration which should ensure the stationarity of the statical...

A method of speaker recognition based on visual comparisons of sets of voice patterns is presented. These sets contain graphical patterns obtained from parameter extraction in the time-domain, frequency-domain and LPC (Linear Predictive Coding). In comparison to classical spectrograms, the parametri...
