摘要:

随着人工智能和智能设备的发展,关键词识别(KWS)正成为一种普遍的需求。最近在这一领域的工作集中在几个不同的架构,以实现良好的结果,低到中等噪声的数据集。然而,这些模型的性能恶化,在高噪声条件下,我们的实验所示。在我们的论文中,我们提出了一个广泛的比较国家的最先进的KWS网络在各种噪声条件下。我们还建议自适应批量归一化作为一种技术,以提高网络的性能时,在训练阶段的噪声文件是未知的。这种高噪声特性的结果使未来的工作,在开发模型,在上述条件下表现更好。

英文摘要:

Keyword spotting (KWS) is becoming a ubiquitous need with the advancement in artificial intelligence and smart devices. Recent work in this field have focused on several different architectures to achieve good results on datasets with low to moderate noise. However, the performance of these models deteriorates under high noise conditions as shown by our experiments. In our paper, we present an extensive comparison between state-of-the-art KWS networks under various noisy conditions. We also suggest adaptive batch normalization as a technique to improve the performance of the networks when the noise files are unknown during the training phase. The results of such high noise characterization enable future work in developing models that perform better in the aforementioned conditions.
