V. Aristov. T.Laimina “ The Use Of The Karhunen Loeve Transformation To Form The Speech Data For Their Subsequent Wiring To Sound By Probing Sound Source By An Ultra-Wideband Pulse Locator” , Žurnāls Austria-science, № 17/ 2018, pp.22-28.
The possibility of applying the first principal component of the Karunen-Loeve transformation is developed to form the speech data for their subsequent wiring to sound when a sound source (speaking person) is probed with an ultrawideband pulse locator.
