摘要:

声场景地理标记是在声场景分类的基础上发展起来的一个新的研究课题。它的动机是音频监控的想法。不满足于只描述录音中的一个场景,一台可以定位录音拍摄地点的机器对许多人来说都是有用的。在本文中,我们探讨了一系列常见的音频数据增强方法,以评估哪种方法最能提高音频地理标记分类器的准确性。我们的工作提高了国家的最先进的城市地理标记方法的23%的分类精度。

英文摘要:

Sound scene geotagging is a new topic of research which has evolved from acoustic scene classification. It is motivated by the idea of audio surveillance. Not content with only describing a scene in a recording, a machine which can locate where the recording was captured would be of use to many. In this paper we explore a series of common audio data augmentation methods to evaluate which best improves the accuracy of audio geotagging classifiers. Our work improves on the state-of-the-art city geotagging method by 23% in terms of classification accuracy.
