ABSTRACT
Based on works such as the one by GUIDO [1], BARBON JR [2], and SOUZA [3], it is clear that the voice provides all the information necessary for their analysis and detection of pathologies in the larynx, by loading extremely important characteristics of the vocal tract. The most common disorders, such as laryngeal edema, generally caused by the use of cigarettes, and the nodules, generated by overexertion of the voice, among other, aect the dynamics of the speech production system as discussed in SCALASSARA [4], generating small variations in acoustic parameters of the vocal tract, when observed over time phonation.
