ReMASC: Realistic Replay Attack Corpus for Voice Controlled Systems

We introduce a new database of voice recordings with the goal of supporting research on vulnerabilities and protection of voice-controlled systems (VCSs). In contrast to prior efforts, the proposed database contains both genuine voice commands and replayed recordings of such commands, collected in realistic VCSs usage scenarios and using modern voice assistant development kits. Specifically, the database contains recordings from four systems (each with a different microphone array) in a variety of environmental conditions with different forms of background noise and relative positions between speaker and device. To the best of our knowledge, this is the first publicly available database1 that has been specifically designed for the protection of state-of-the-art voice-controlled systems against various replay attacks in various conditions and environments.

本团队推出一项新型语音录音数据库，旨在支持对语音控制系统（VCSs）的脆弱性及其保护机制的研究。与以往的努力不同，本数据库不仅包含真实的语音指令，还收录了此类指令的重放录音，这些录音是在现实VCSs使用场景下，利用现代语音助手开发套件所采集。具体而言，数据库中包含了来自四个系统（每个系统配备不同的麦克风阵列）在各种环境条件下，伴随不同形式的背景噪声以及说话人与设备间相对位置差异的录音。据我们所知，这是首个专为在多种条件和环境下保护最先进语音控制系统免受各类重放攻击而特别设计的公开可用数据库。
