  This document describes the Short-duration Speaker Verification (SdSV)
Challenge 2021. The main goal of the challenge is to evaluate new technologies
for text-dependent (TD) and text-independent (TI) speaker verification (SV) in
a short duration scenario. The proposed challenge evaluates SdSV with varying
degree of phonetic overlap between the enrollment and test utterances
(cross-lingual). It is the first challenge with a broad focus on systematic
benchmark and analysis on varying degrees of phonetic variability on
short-duration speaker recognition. We expect that modern methods (deep neural
networks in particular) will play a key role.
