Abstract
Using a Fourcin laryngograph, Lx recordings of three male speakers were made. After manipulation, the Lx signals were presented to a group of eight listeners, who performed both an AX discrimination and a speaker identification test. The results show that the listeners made use of the three parameters varied in the listening tests, viz. speech rhythm, F0 contour and F0 height. Furthermore, the data suggest that the relevance of these different parameters for speaker recognition is speaker-dependent rather than absolute.
