Modeling drivers' speech under stress
In this paper we explore the use of features derived from multiresolution analysis of speech and the Teager Energy Operator for classi cation of drivers' speech under stressed conditions. We apply this set of features to a database of short speech utterances to create userdependent discriminants of four stress categories. In addition we address the problem of choosing a suitable temporal scale ...
متن کاملClassification of speech under stress by modeling the aerodynamics of the laryngeal ventricle
We focus on variations in the aerodynamics of airflow patterns in the laryngeal ventricle and the false vocal folds based on a physical model for the classification of neutral and stressed speech. We modify the two-mass model to include the laryngeal ventricle, and the physical parameters characterizing airflow variations in the laryngeal ventricle under psychological stress are explored. The t...
متن کاملSubband based classification of speech under stress
This study proposes a new set of feature parameters based on subband analysis of the speech signal for classi cation of speech under stress. The new speech features are Scale Energy (SE), Autocorrelation-Scale-Energy (ACSE), Subband based cepstral parameters (SC), and Autocorrelation-SC (ACSC). The parameters' ability to capture di erent stress types is compared to widely used Mel-scale cepstru...
متن کاملSpeech Under Stress: Analysis, Modeling and Recognition
In this chapter, we consider a range of issues associated with analysis, modeling, and recognition of speech under stress. We start by defining stress, what could be perceived as stress, and how it affects the speech production system. In the discussion that follows, we explore how individuals differ in their perception of stress, and hence understand the cues associated with perceiving stress....
متن کاملClassification of speech under stress based on modeling of the vocal folds and vocal tract
In this study, we focus on the classification of neutral and stressed speech based on a physical model. In order to represent the characteristics of the vocal folds and vocal tract during the process of speech production and to explore the physical parameters involved, we propose a method using the two-mass model. As feature parameters, we focus on stiffness parameters of the vocal folds, vocal...
