Chih-Chien T. Chen, Chin-Ta Chen, Chih-Ming Tsai · Electronics Letters · 1997
A text independent speaker recognition system based on hard-limited eigenfunctions derived from the Karhunen-Loeve transform is proposed. Two databases, each with 100 Mandarin speakers, are collected for system evaluation. It is demonstrated that > 94% correct classification rates can be achieved by the use of the first 32 hard-limited features.
