USTCSpeech System for VOiCES from a Distance Challenge 2019

This document describes the speaker verification systems developed in the Speech lab at the University of Science and Technology of China (USTC) for the VOiCES from a Distance Challenge 2019. We develop the system for the Fixed Condition on two public corpus, VoxCeleb and SITW. The frameworks of our systems are based on the mainstream ivector/PLDA and x-vector/PLDA algorithms.
