This paper proposes a new approach to improve the amount of information extracted from
the speech aiming to increase the accuracy of a system developed for the automatic …

In this paper, we propose to quantify the quality of the recorded voice through objective
nonlinear measures. Quantification of speech signal quality has been traditionally carried …

Previous studies have shown that the underlying process of speech generation exhibits
nonlinear characteristics. Since linear features cannot represent a nonlinear system …

Acoustic analysis of voice features can complete the invasive observation-based methods
for the diagnosis of vocal fold pathologies. Selection of an appropriate feature extraction …

This work describes a novel methodology to characterize voice diseases by using nonlinear
dynamics, considering different complexity measures that are mainly based on the analysis …

In this paper we propose the use of nonlinear speech features to improve the voice quality
measurement. We have tested a couple of features from the Dynamical System Theory …

Automatic voice pathology detection and classification systems effectively contribute to the
assessment of voice disorders, enabling the early detection of voice pathologies and the …

This paper presents a study of the approaches in the state-of-the-art in the field of
pathological speech signal analysis with a special focus on parametrization techniques. It …

The use of noninvasive techniques to evaluate the larynx and vocal tract helps the speech
specialists to perform accurate diagnose of diseases. In this study, a method to distinguish …

It is well known that most laryngeal diseases and vocal fold pathologies cause significant
changes in speech. Different procedures of clinical application for laryngeal examination …
