Making Confident Speaker Verification Decisions with Minimal Speech

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.
