It is well known that most of vocal fold pathologies cause changes in the acoustic voice signal. Therefore, the voice signal can be a useful tool to diagnose them. Acoustic voice analysis can be used to characterize the pathological voices. This paper presents the detection of vocal fold pathology with the aid of the speech signal recorded from the patients. The speech samples from Massachusetts Eye and Ear Infirmary (MEEI) database are used to evaluate the scheme. Time-domain features based on energy variation are proposed and extracted from the speech to form a feature vector. In order to test the effectiveness and reliability of the proposed time-domain features, a Probabilistic Neural Network (PNN) is employed. The experimental results show that the proposed features gives very promising classification accuracy and can be effectively used to detect the vocal fold pathology clinically. 2010-11-16T01:04:48Z 2010-11-16T01:04:48Z 2010 Article Malaysian Journal of Computer Science, vol. 23(1), 2010, pages 60-67 0127-9084 http://mjcs.fsktm.um.edu.my/document.aspx?FileName=878.pdf http://hdl.handle.net/123456789/10222 en Universiti Malaya
