    "description": "<p>The automatic speaker verification spoofing and countermeasures (ASVspoof) challenge series is a&nbsp;community-led initiative which aims to promote the consideration of spoofing and the development of&nbsp;countermeasures. &nbsp;ASVspoof 2021 is the 4th in a series of bi-annual, competitive challenges where the&nbsp;goal is to develop countermeasures capable of discriminating between bona fide and spoofed or deepfake&nbsp;speech.&nbsp;<br>\n<br>\nASVspoof 2021 comprises three different tasks: &nbsp; &nbsp;<br>\n<em>&nbsp;Logical access (LA)</em>: bona fide and spoofed utterances generated using text-to-speech (TTS) and voice&nbsp;conversion (VC) algorithms are communicated across telephony and VoIP networks with various coding&nbsp;and transmission effects;<br>\n&nbsp; &nbsp;&nbsp;<br>\n<em>Physical access (PA)</em>: bona fide utterances are made in a real, physical space in which spoofing attacks&nbsp;are captured and then replayed within the same physical space using replay devices of varying quality;<br>\n&nbsp; &nbsp;&nbsp;<br>\n<em>Speech deepfake (DF)</em>: a fake audio detection task comprising bona fide and spoofed utterances&nbsp;generated using TTS and VC algorithms. Similar to the LA task (includes compressed data) but without&nbsp;speaker verification.<br>\n<br>\n<strong>This repository provides the evaluation set for the PA task.</strong><br>\n<br>\nFor more details, please visit our website below. https://www.asvspoof.org</p>"
