Environmental noise monitoring systems continuously measure sound levels without assigning these measurements to different noise sources in the acoustic scenes, therefore incapable of identifying the main noise source. In this paper a feasibility study is presented on a new monitoring concept in which an acoustic pattern classification algorithm running in a wireless sensor is used to automatically...
This paper targets on a generalized vocal mode classifier (speech/singing) that works on audio data from an arbitrary data source. Previous studies on sound classification are commonly based on cross-validation using a single dataset, without considering training-recognition mismatch. In our study, two experimental setups are used: matched training-recognition condition and mismatched training-recognition...
This paper proposes a novel active learning method to save annotation effort when preparing material to train sound event classifiers. K-medoids clustering is performed on unlabeled sound segments, and medoids of clusters are presented to annotators for labeling. The annotated label for a medoid is used to derive predicted labels for other cluster members. The obtained labels are used to build a classifier...
