  FFSVC2022 is the second challenge of far-field speaker verification.
FFSVC2022 provides the fully-supervised far-field speaker verification to
further explore the far-field scenario and proposes semi-supervised far-field
speaker verification. In contrast to FFSVC2020, FFSVC2022 focus on the
single-channel scenario. In addition, a supplementary set for the FFSVC2020
dataset is released this year. The supplementary set consists of more recording
devices and has the same data distribution as the FFSVC2022 evaluation set.
This paper summarizes the FFSVC 2022, including tasks description, trial
designing details, a baseline system and a summary of challenge results. The
challenge results indicate substantial progress made in the field but also
present that there are still difficulties with the far-field scenario.
