BACKGROUND Inhaled corticosteroids have the potential to produce upper-airway side effects such as hoarseness. As new compounds and delivery devices are developed and compared, it is difficult to quantify their adverse upper-airway effects. OBJECTIVE We undertook the following study to test the ability of an acoustic analysis technique to quantify changes in vocal function in steroid-naive pa...

The introduction, in the late 70s, of the first digital spectrograph (DSP Sonograph) by Kay Elemetrics has improved the possibilities of spectroacoustic voice analysis in the clinical field. Thanks to the marketing, in 1993, of the Multi Dimensional Voice Program (MDVP) advanced system, it is now possible to analyse 33 quantitative voice parameters which, in turn, allow evaluation of fundamenta...

Introduction: Objective and perceptual acoustic voice assessments are recommended as complimentary parts for clinical voice examinations [1]. However, in hoarse voices there have been contradictory descriptions of the correlation between perceptual and objective acoustic analysis [2, 3]. One reason might be the low reliability of objective acoustic measurements in irregular voice signals, which...

Clinical acoustic voice-recording analysis is usually performed using classical perturbation measures, including jitter, shimmer, and noise-to-harmonic ratios (NHRs). However, restrictive mathematical limitations of these measures prevent analysis for severely dysphonic voices. Previous studies of alternative nonlinear random measures addressed wide varieties of vocal pathologies. Here, we anal...

OBJECTIVES 1) To apply perceptual and acoustic voice assessments to children treated for juvenile-onset recurrent respiratory papillomatosis (JORRP); 2) to compare voice outcomes following treatment for JORRP using microdebrider versus carbon dioxide (CO(2)) laser. STUDY DESIGN Prospective cohort study. SETTING This study was conducted at a tertiary pediatric academic center (March 2008-Mar...

9 Clinical acoustic voice recording analysis is usually performed using classical perturbation measures 10 including jitter, shimmer and noise-to-harmonic ratios. However, restrictive mathematical 11 limitations of these measures prevent analysis for severely dysphonic voices. Previous studies of 12 alternative nonlinear random measures addressed wide varieties of vocal pathologies. Here, we 13...

BACKGROUND Long-term low frequency noise exposure (LFN) (< or = 500 Hz, including infrasound) may lead to the development of vibroacoustic disease (VAD), a systemic pathology characterized by the abnormal growth of extra-cellular matrices. The respiratory system is a target for LFN. Fibrosis of the respiratory tract epithelia was observed in VAD patients through biopsy, and confirmed in animal ...

Fake audio detection (FAD) aims to identify fraudulent speech generated through advanced speech-synthesis techniques. Most current FAD methods rely solely on a deep neural network (DNN) framework with either waveforms or commonly used acoustic features extract high-level representations, overlooking the analysis of prosody differences between genuine and fake speech. Prosody carries important c...
