Abstract :
Joint time-frequency signal representations, such as the Wigner-Ville distribution, have been applied to the analysis of signals containing transients. The authors estimate the Wigner distribution via robust linear predictive methods, followed by application of the Karhunen-Loeve transformation in order to capture frequency transients. Use of this technique may lead to reliable speech acoustic subword segmentation
