Voice Activity Detection and Pitch analysis in Pathological Voices

This paper presents the voice activity detection (VAD) using basic parameters. The voice is found to have hoarseness in case of thyroid and laryngeal cancer patients. It is useful for the better analysis of pathological voices in presence of background noise. Automatic voice pathology detection and classification is important in the voice disorder assessment. Here, two pitch detection algorithms are used for the analysis. This enhanced voice enables the early detection and diagnosis of type of pathology related to the patient. Mr. G.B. Gour | Dr. V.
