Abstract

Voice analysis can be used for many purposes, e.g. diagnostics or voice damage prevention. The voice can be easily damaged especially by excessive or incorrect usage. This work describes basics of anatomy, physiology and pathology of voice. The major part is focused on acoustic analysis. It also describes the procedure of measurement on Voice Diagnostic Center lingWAVES. In the practical part the parameters of selected vowels were measured with the system Vospector. These obtained information were processed into the database of voice measurement results of individual pedagogues. Results were compared and evaluated and then inserted into graphs. To better visualize the results there was created an application that allows simultaneous rendering of selected vowels evaluations. This application eliminates the disadvantage of the Voice Diagnostic Center which is able to watch results of single vowel, however does not allow their comparison. Another advantage of created application is that it divides parameters into multiple areas, allowing more accurate evaluation of voice.
