This is a case-control study investigating the personality profiles of children with vocal fold nodules (VFNs). Personality has been suggested as a contributing factor to VFN in adults and in children. However, previous studies in children have focused on psychopathologic traits and have reported contradictory findings. The aim of our study was to explore whether general, nonpathologic personality structure predicts the presence of VFN in children. Personality traits were measured in 34 children with VFN, aged 6...

OBJECTIVES: Generalization is a challenging phase in voice therapy, involving the implementation of a targeted voice technique in all spoken communication. Among other barriers to generalization, self-consciousness keeps patients from practicing and recalibrating their voice technique when they can be overheard (eg, at work). We developed an iOS application that covertly assists users in producing their target voice while they appear to be engaged in a cellular phone call. METHODS: To examine the feasibility of this Fake Phone Call, 11 adults in the generalization stage of voice therapy received a simulated call four times daily for 1 week...

INTRODUCTION: Adductor spasmodic dysphonia (ADSD) is one of the most disabling voice disorders with no permanent cure. Patients with ADSD suffer from poor voice quality and repeated interruption of phonation that leads to limitations in daily communication. Botox (BT) injection, considered the gold standard treatment for ADSD, reduces the amount of voice breaks and improves voice quality for a limited period. In this study, patients with ADSD were followed after a single BT injection to track the changes in QOL and perceptual voice quality over a 6-month period...

Christian T Herbst, Jacob C Dunn
Fundamental frequency (fo ) is often estimated based on electroglottographic (EGG) signals. Because of the nature of the method, the quality of EGG signals may be impaired by certain features like amplitude or baseline drifts, mains hum, or noise. The potential adverse effects of these factors on fo estimation have to date not been investigated. Here, the performance of 13 algorithms for estimating fo was tested, based on 147 synthesized EGG signals with varying degrees of signal quality deterioration. Algorithm performance was assessed through the standard deviation σfo of the difference between known and estimated fo data, expressed in octaves...

OBJECTIVE: The phonatory process is often judged during sustained phonation by analyzing the acoustic voice signal and the vocal fold vibrations. Many formulas and parameters have been suggested for qualifying the characteristics of the acoustic signal and the vocal fold vibrations during sustained phonation. These parameters are directly computed from the acoustic signal and the endoscopic glottal area waveform (GAW). The GAW is calculated from laryngeal high-speed videoendoscopy (HSV) recordings and describes the increase and decrease of the glottal area during the phonation process, that is, the opening and closing of the two oscillating vocal folds over time...

OBJECTIVES: The purpose of this work was twofold. First, we aimed to develop an exact analytical model for tubes used in semi-occluded vocal tract exercises to gain a quantitative insight into the relationship between flow resistance and the tube's geometric parameters. The second goal was to provide an isometric resistance chart that can be used by clinicians to indicate either the diameter or the length of a tube, so as to provide the same flow resistance of a reference tube. METHODS: The theory for confined flows based on the Darcy-Weisbach equation was used to derive the analytical model, in which the friction factor was obtained by an explicit approximation with error smaller than 0...
