摘要:

定位和跟踪声学事件的能力是使机器具备感知和参与周围环境中的人类的能力的基本先决条件。然而,在现实场景中,音频信号受到混响、噪声、干扰和语音不活动时段的不利影响。在源和麦克风平台可能正在移动的动态场景中,信号还受到源-传感器几何形状变化的影响。在实际应用中,声源定位和跟踪的方法往往受到漏估计、估计误差以及错误估计的阻碍。LOCATA挑战赛的目标是一个开放获取的框架,用于对声源定位和跟踪的广泛算法进行客观评估和基准测试。本文提供了相关的定位和跟踪算法的审查,并在现有的文献,详细的评估和传播的LOCATA提交的背景下。评价突出了在该领域取得的成就、面临的挑战,并确定了未来的潜在方向。

英文摘要:

The ability to localize and track acoustic events is a fundamental prerequisite for equipping machines with the ability to be aware of and engage with humans in their surrounding environment. However, in realistic scenarios, audio signals are adversely affected by reverberation, noise, interference, and periods of speech inactivity. In dynamic scenarios, where the sources and microphone platforms may be moving, the signals are additionally affected by variations in the source-sensor geometries. In practice, approaches to sound source localization and tracking are often impeded by missing estimates of active sources, estimation errors, as well as false estimates. The aim of the LOCAlization and TrAcking (LOCATA) Challenge is an open-access framework for the objective evaluation and benchmarking of broad classes of algorithms for sound source localization and tracking. This article provides a review of relevant localization and tracking algorithms and, within the context of the existing literature, a detailed evaluation and dissemination of the LOCATA submissions. The evaluation highlights achievements in the field, open challenges, and identifies potential future directions.
