DESCRIPTION:The presentation consists of two parts. In the first one\, the 
 typical signals applied for testing of electro-acoustical devices are pres
 ented. These signals are e.g: harmonic signal\, slowly and quickly tuned s
 inusoid\, impulses\, Gaussian noise\, Maximum Length Sequence\, Golay’s 
 Complementary Sequences. The statistical and spectral properties of these 
 signals are described. The methods of analysis of stationary and nonstatio
 nary signals are presented as well. In the second part\, the signals used 
 for the evaluation of quality of coded and transmitted speech are presente
 d. For this aim\, the natural or artificial speech signals are used. The t
 est material can consist of units having semantic meaning as well as of no
 nsense syllables or words. For the Polish language\, the Polish Standard p
 rovides a set of logatome lists. American ANSI norms include\, among other
 s\, rhyme tests. The International Telecommunication Union (ITU-T) guideli
 nes specify the requirements for the test signal base for telecommunicatio
 ns applications. This recommendation presents a set of test signals of var
 ious complexity with many typical speech parameters. These signals are int
 ended for both subjective and objective evaluation of the quality of speec
 h transmission.\n\nSpeaker(s): Andrzej Dobrucki\, Stefan Brachmański\n\nP
