The objective of this study is to evaluate the reliability of acoustic voice parameters obtained using smart phone (SP) microphones and investigate the utility of use of SP voice recordings for voice screening. Voice samples of sustained vowel/a/obtained from 118 subjects (34 normal and 84 pathological voices) were recorded simultaneously through two(More)
OBJECTIVE To culturally adapt the Glottal Function Index (GFI) questionnaire to the Lithuanian language, and to validate it. METHODS Psychometric analyses were performed on the translated Lithuanian version of the GFI (GFI-LT) as described by the Scientific Advisory Committee of the Medical Outcomes Trust. The GFI-LT was completed by 50 voice-disordered(More)
The purpose of this study was to evaluate quantitatively the parameters of the video laryngostroboscopy (VLS) and determine correlations between the VLS parameters and acoustic vocal function parameters. Digital VLS recordings, acoustic voice assessment, calculation of dysphonia severity index (DSI) and registration of voice range profile (VRP) were(More)
This paper is concerned with kernel-based techniques for automated categorization of laryngeal colour image sequences obtained by video laryngostroboscopy. Features used to characterize a laryngeal image are given by the kernel principal components computed using the N -vector of the 3-D colour histogram. The least squares support vector machine (LS-SVM) is(More)
OBJECTIVE The aim of this study is to evaluate the correlations among the basic video laryngostroboscopic (VLS) parameters and vocal function assessed using a multidimensional set of perceptive, acoustic, aerodynamic, and subjective measurements. METHODS Digital VLS recordings and multidimensional voice assessment were performed for 108 individuals,(More)
This paper is concerned with soft computing techniques-based noninvasive monitoring of human larynx using subject’s questionnaire data. By applying random forests (RF), questionnaire data are categorized into a healthy class and several classes of disorders including: cancerous, noncancerous, diffuse, nodular, paralysis, and an overall pathological class.(More)
OBJECTIVE The purpose of this study was to evaluate quantitatively the basic parameters of the video laryngostroboscopy (VLS) and determine the sensitivity and specificity of these parameters discriminating healthy and pathological voice classes. METHODS Digital VLS recordings were performed for 159 individuals: 26 healthy and 133 patients. VLS variables(More)
