  The VoicePrivacy Challenge aims to promote the development of privacy
preservation tools for speech technology by gathering a new community to define
the tasks of interest and the evaluation methodology, and benchmarking
solutions through a series of challenges. In this document, we formulate the
voice anonymization task selected for the VoicePrivacy 2020 Challenge and
describe the datasets used for system development and evaluation. We also
present the attack models and the associated objective and subjective
evaluation metrics. We introduce two anonymization baselines and report
objective evaluation results.
