1. The use of Wavelet packet transform and artificial neural networks in analysis and classification of dysphonic voices
This paper presents a dysphonic voice classification system using the wavelet packet transform and the best basis algorithm (BBA) as dimensionality reductor and 06 artificial neural networks (ANN) acting as specialist systems. Each ANN was a 03-layer multilayer perceptron with 64 input nodes, 01 output node and in the intermediary layer the number of neurons

2. Perceptual and acoustical analysis in women. with vocal node / AnÃlise perceptivo-auditiva e acÃstica em mulheres com nÃdulos vocais
This work ayms to study the perceptual evaluation and the acoustic analysis in 25 women. In this population, 20 women had vocal nodule and 5 had normal voices and larynx. It was defined the vocal node as the interest pathology, which is a reaction to the excessive use of the voice, that induces to the constant vocal folds movement. It was used VoxMetria soft

3. Avaliação vocal e atividade eletrica dos musculos supra-hioideos e esternocleidomastoideo em individuos com desordem temporomandibular miogenica em situações de repouso e fonação
The aim of this study was to evaluate the voice and mesure the electrical activity of suprahyoid (SH) and esternocleidomastoid (SCM) muscles in subjects with temporomandibular joint disorder, in rest and speaking situations. By means of surface eletromyographic, were assessed the SCM left and right muscles, as well as the SH muscles of 20 female individuais,
