摘要:

最近的声事件分类研究集中在训练合适的滤波器来表示声事件。然而,由于目标事件数据库的有限可用性和传统滤波器的线性,仍然存在改进性能的空间。通过利用深度神经网络(DNN)的非线性建模及其在预训练环境之外学习的能力,这封信提出了一种基于DNN的特征提取方案,用于声学事件的分类。室内监控环境数据库的使用证明了所提出的方法的有效性和鲁棒性的噪声。

英文摘要:

Recent acoustic event classification research has focused on training suitable filters to represent acoustic events. However, due to limited availability of target event databases and linearity of conventional filters, there is still room for improving performance. By exploiting the non-linear modeling of deep neural networks (DNNs) and their ability to learn beyond pre-trained environments, this letter proposes a DNN-based feature extraction scheme for the classification of acoustic events. The effectiveness and robustness to noise of the proposed method are demonstrated using a database of indoor surveillance environments.
