Effect of sample duraition and temporal resolution on perturbation measurements

Abstract

Voice is the laryngeal modulation of pulmonary air stream which is further modified by the configuration of vocal tract, (Michael and Wendhal, 1971). Voice plays an important role in speech communication. The production of voice requires a complex and precise control by the central nervous system on a series of synchronous events in respiratory, phonatory and resonatory systems. Any anatomical and physiological deviation in these systems would lead to voice disorder. The evaluation of voice includes acoustic analysis of voice. The acoustic analysis of voice may be one of the most powerful and attractive method for assessing the phonatory function as it is non-invasive, objective and quantitative.
