论文摘要

爆发后两年多,Covid-19的大流行继续困扰着世界各地的医疗系统,给稀缺资源带来压力,并夺走了人类的生命。从一开始,已经采用了各种基于AI的COVID-19检测和监测工具,以试图通过及时的诊断来阻止感染的潮流。特别是,已经建议计算机试听是一种非侵入性,成本效益和环保的替代方法,可通过声音通过声音来检测COVID-19的感染。但是,像所有AI方法一样,计算机试镜也很大程度上取决于可用数据的数量和质量,并且由于此类数据的敏感性,大规模的COVID-19声音数据集也很难获取。为此,我们介绍了Covyt数据集 - 一种新颖的Covid-19数据集,该数据集是从包含来自65位讲话者的8个小时以上演讲的公共资源中收集的。与其他现有的COVID-19声音数据集相比,COVYT数据集的独特功能是,它包括所有65位扬声器的covid-19正面和负样本。我们使用可解释的音频描述来分析Covid-19的声学表现,并使用可解释的音频描述,并研究了几种分类场景,并调查了一些分类场景,这些方案将基于公平的言语的COVID-19检测示出适当的分区策略。

More than two years after its outbreak, the COVID-19 pandemic continues to plague medical systems around the world, putting a strain on scarce resources, and claiming human lives. From the very beginning, various AI-based COVID-19 detection and monitoring tools have been pursued in an attempt to stem the tide of infections through timely diagnosis. In particular, computer audition has been suggested as a non-invasive, cost-efficient, and eco-friendly alternative for detecting COVID-19 infections through vocal sounds. However, like all AI methods, also computer audition is heavily dependent on the quantity and quality of available data, and large-scale COVID-19 sound datasets are difficult to acquire -- amongst other reasons -- due to the sensitive nature of such data. To that end, we introduce the COVYT dataset -- a novel COVID-19 dataset collected from public sources containing more than 8 hours of speech from 65 speakers. As compared to other existing COVID-19 sound datasets, the unique feature of the COVYT dataset is that it comprises both COVID-19 positive and negative samples from all 65 speakers. We analyse the acoustic manifestation of COVID-19 on the basis of these perfectly speaker characteristic balanced `in-the-wild' data using interpretable audio descriptors, and investigate several classification scenarios that shed light into proper partitioning strategies for a fair speech-based COVID-19 detection.
