Several methods—laryngoscopy, stroboscopy, thermography, electromyography, pneumotachography, glottography, and acoustic analysis—have been used in laryngeal research applied anatomy and physiology for speech-language pathology and audiology pdf diagnosis.
However, for routine clinical evaluation of laryngeal function, acoustic analysis has an advantage over the other methods because of its non-intrusive nature and its potential for providing quantitative data with reasonable expenditures of analysis time. This chapter discusses the methods for the acoustic analysis of voices that are affected by laryngeal pathology and procedures for determining acoustic parameters applicable to screening and to clinical assessment. These methods use digital computer techniques for voice analysis to extract acoustic measures of vocal function from the speech signal. The vocal fold movement is related to the acoustic output on which the acoustic methods are based, and the theoretical bases and results of several methods are compared, indicating the problems that require additional research.
