NIST and NFI-TNO evaluations of automatic speaker recognition

In the past years, several text-independent speaker recognition evaluation campaigns have taken place. This paper reports on results of the NIST evaluation of 2004 and the NFI-TNO forensic speaker recognition evaluation held in 2003, and reflects on the history of the evaluation campaigns. The effects of speech duration, training handsets,...

Mutual dependence of the octave-band weights in predicting speech intelligibility

Current objective measures for predicting the intelligibility of speech by an index assume that this can be obtained by simple addition of the contributions of individual frequency bands. The Articulation Index (AI, and the related Speech Intelligibility Index), and the Speech Transmission Index (STI) are based on this assumption. There is...
