Abstract :
In this paper, we describe the classification of audio signals recorded in all-night sleep studies. Our objective is to separate the episodes into snoring sounds and non-snoring sounds. To begin with, we employ hierarchical classification schemes to classify sounds into human sounds and non-human sounds. We then attempt to organize human sounds into snore and non-snore segments based on their acoustic properties. We perform further analysis of the extracted snoring sounds to check if the testee has apnea. Experimental results have validated the efficacy of the proposed method
