background: repeated efforts by researchers to impose voice changes by laryngeal surface electrical stimulation (ses) have come to no avail. this present pre-experimental study employed a novel method for ses application so as to evoke the motor potential of the internal superior laryngeal nerve (isln) and create voice changes. methods: thirty-two normal individuals (22 females and 10 males) pa...

OBJECTIVES Vocally trained actresses are expected to have more vocal economy than nonactresses. Therefore, we hypothesize that there will be differences in the electroglottogram-based voice economy parameter quasi-output cost ratio (QOCR) between actresses and nonactresses. This difference should remain across different levels of intensity. METHODS A total of 30 actresses and 30 nonactresses ...

Deep brain stimulation of the subthalamic nucleus (STN-DBS) in patients with Parkinson's disease (PD) affects speech inconsistently. Recently, stimulation of the caudal zona incerta (cZi-DBS) has shown superior motor outcomes for PD patients, but effects on speech have not been systematically investigated. The aim of this study was to compare the effects of cZi-DBS and STN-DBS on voice intensit...

As basic parameters in speech processing we regard pitch, duration, intensity, voice quality, signal to noise ratio, voice activity detection and strength of Lombard effect. Taking in account also adverse conditions the performance of many published algorithms to extract those parameters from the speech signal automatically is not known. A framework based on competitive evaluation is proposed t...

BACKGROUND The term ‘‘vocal fold nodules’’ refers to bilateral thickening of the membranous folds, with minimal impairment of the vibratory properties of the mucosa. They are considered to be related to repetitive mechanical stress, typically related to voice use patterns. Diagnosis is made in the office via either rigid or flexible laryngeal stroboscopy. The reported incidence of vocal fold no...

The degree of glottal closure during phonation has an influence on voice quality and it is related to the robustness of the voice source. To quantify glottal closure a frame of reference was created by investigating 47 healthy men and 92 healthy women with no vocal complaints using videolaryngostroboscopy. Observing recorded images the degree of glottal closure was rated with a percentage. Resu...

OBJECTIVE Determining the relationship between vocal habits and environmental/ occupational conditions with the presence of vocal disturbance (dysphonia) in teachers and functionaries working at community-based, initial childhood education centres (kindergartens). METHOD This was a descriptive study which adopted across-sectional approach using 198 participants which was developed in three ph...

In this paper, we propose and analyze a service-dependent handoff and channel allocation scheme in voice and data integrated cellular mobile systems, which combines the ideas of " Variable Bandwidth " and " Preemptive Priority " together. In the scheme, voice and data traffic are considered. According to the variations of the offered traffic intensity at each cell, both a voice and a data call ...

ABSTRACT Purpose To analyze the passaggio in voice range profile of choristers, by identifying fundamental frequencies and intensities, both change to high low registers, comparing them, types. Method 67 choristers participated, mean age 27.79 (± 7.50) years old, following types: soprano (n = 20), alto 17), tenor 15) bass 15). For data collection analysis, Vocalgram software (CTS Informática) w...
