Title in Portuguese
Perfis acústicos para caracterização de patologias da laringe
Keywords in Portuguese
Análise acústica da voz
Doenças da laringe
Processamento digital de sinais
Abstract in Portuguese
A caracterização das patologias da laringe até o presente momento é predominantemente realizada de forma qualitativa. Alguns trabalhos recentes têm quantificados parâmetros acústicos no intuito de discriminar as diversas patologias. Este trabalho verifica os valores médios das diversas medidas acústicas da voz e as relaciona com as diferentes patologias. Desta forma, futuramente será possível utilizar estes valores para quantificar e acompanhar diferentes estágios do tratamento da patologia. O conjunto de valores médios compõem o que chamamos de perfil acústico.

Abstract in English
Until now the characterization of larynx pathologies has been done in a subjective manner. Recently some researches have been conducted in order to quantify acoustic parameters mainly to discriminate the larynx pathologies. In this work several acoustic parameters of voice was evaluated and their correlation with the pathologies were established. In the future, would be possible to use these parameters to quantify and to follow the therapy procedures. These values constitute the acoustic profile of the pathologies.
