Making confident speaker verification decisions with minimal speech

Vogt, Robert J., Sridharan, Sridha, & Mason, Michael W. (2008) Making confident speaker verification decisions with minimal speech. In 9th Annual Conference of the International Speech Communication Association (Interspeech 2008) incorporating the 12th Australasian International Conference on Speech Science and Technology (SST 20008), 22-26 September 2008, Brisbane Australia.


Drastic reductions in the typical data requirements for producing confident decisions in an automatic speaker verification system are demonstrated through the application of a novel approach of score confidence interval estimation. The confidence estimation procedure is also extended to produce robust results with very limited and highly correlated frame scores. The early verification decision method evaluated on the 2005 NIST SRE protocol demonstrates that an average of 2–10 seconds of speech is sufficient to produce verification results approaching those achieved previously using an average of over 100 seconds of speech.

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
