Even violins can cry: specifically vocal emotional behaviours also drive the perception of emotions in non-vocal music.
2021
A wealth of theoretical and empirical arguments have suggested that music triggers emotional responses by resembling the inflections of expressive vocalizations, but have done so using low-level acoustic parameters (pitch, loudness, speed) that, in fact, may not be processed by the listener in reference to human voice. Here, we take the opportunity of the recent availability of computational models that allow the simulation of three specifically vocal emotional behaviours: smiling, vocal tremor and vocal roughness. When applied to musical material, we find that these three acoustic manipulations trigger emotional perceptions that are remarkably similar to those observed on speech and scream…
Comparison between Minimally Invasive Video-Assisted Thyroidectomy and Conventional Thyroidectomy: Is There Any Evidence-Based Information?
2008
The aim of this study was to test the hypothesis that minimally invasive video-assisted thyroidectomy (MIVAT) affords comparable safety and efficacy as to the open conventional surgery in dealing with patients with small thyroid nodules.Randomized controlled trials comparing the MIVAT with open thyroidectomy were ascertained by methodical search using Medline, Embase, Pubmed, and The Cochrane Library. Primary meta-analysis outcomes were adverse events (laryngeal nerve palsy and hypoparathyroidism), and cosmesis and secondary outcomes were operative time, blood loss, and early and late postoperative pain.Operative time was significantly less with open thyroidectomy than with MIVAT, while MIV…
Value of Neurostimulation Plus Laryngeal Palpation to Predict Postoperative Vocal Fold Motility.
2021
ABSTRACT Background The aim of this study was to evaluate the reliability of intraoperative neuromonitoring through recurrent laryngeal nerve stimulation and simultaneous laryngeal palpation (NSLP) in predicting postoperative vocal cord palsy and in providing useful information in the decision to perform a staged surgery in initially planned total thyroidectomy. Materials and Methods A retrospective review was performed involving 552 patients for whom a total thyroidectomy was planned. In all patients, preoperative and postoperative laryngoscopy was performed. The incidence of vocal cord palsy was calculated on 1104 nerves at risk. Results Sensitivity and specificity of NSLP were 0.9411 and…
Roentgenological observations on vocal fold length-changes with special reference to register transition and open/covered voice
1992
This paper examines the length-changes of the vocal folds as a function of voice pitch. Changes in normalized vocal fold elongation (strain) were measured indirectly from calcification points in several laryngeal structures from roentgenological exposures during singing. Changes in vocal fold strain are shown to occur mainly in the register transition area, i.e. the area within which all register changes take place. Changes in vocal fold strain appeared similar in male and female subjects. Evidence for different strain patterns in covered and open singing is presented for female subjects: Strain is higher in non-singers and (“incorrect”) open voice, lower in singers and (“correct”) covered …
Vocal Tract Discomfort Scale (VTDS) and Voice Symptom Scale (VoiSS) in the early identification of Italian teachers with voice disorders
2019
Abstract Introduction The current Italian law does not include any guidance regarding voice education, prevention of voice disorders and screening in subjects with high vocal loading such as teachers. Objectives We aimed to check the correlation between the Vocal Tract Discomfort Scale (VTDS) with the Voice Symptom Scale (VoiSS) for the evaluation of Italian teachers. In addition, we aimed to investigate whether there are differences in the frequency and intensity of discomfort symptoms in teachers with disabilities comparing vocal tract discomfort symptoms in teachers with high risk (HRVD) and low risk (LRVD) of vocal disorders according to the VoiSS cutoff (> 15.5). Methods We analyzed…
Complete Vocal Technique laulunopetuksen välineenä lukion musiikinopetuksessa
2015
Tutkimuksen tarkoituksena on selvittää miten Complete Vocal Technique (CVT) nimistä tanskalaista laulutekniikkaa voidaan hyödyntää lukion musiikinopetuksen laulunopetuksessa. Kyseistä laulutekniikkaa käytetään niin pop/jazz-laulun, kuin klassisen laulunkin opetuksessa. Se on selkeä, yksinkertainen ja monenlaiset oppijat huomioon ottava laulutekniikka, jonka avulla opiskelijat voivat oppia ymmärtämään laulamista ja rohkaistua käyttämään omaa ääntään. Tutkimus on toimintatutkimus. Pidin kolme Complete Vocal Techniqueen liittyvää laulutyöpajaa yhdelle musiikin 1. kurssin lukiolaisryhmälle. Koska tutkimuksessa oli mukana vain yksi lukiolaisryhmä, on tutkimus myös tapaustutkimus. Työpajojen jälk…
L’utilisation des mécanismes de maintien de l’information verbale en mémoire de travail chez l’enfant de 8 ans
2010
La mémoire de travail est une forme de mémoire immédiate qui permet de retenir des informations tout en effectuant simultanément un traitement sur ces informations ou sur d’autres informations. Elle est indispensable dans la vie quotidienne, par exemple sans elle nous serions incapable de comprendre une phrase ou de résoudre une opération. Les informations stockées dans cette mémoire ne peuvent être maintenues que pendant un très bref instant (± 2 secondes). Cependant, il est possible de les retenir pendant une plus longue durée en utilisant des mécanismes de maintien. Actuellement deux mécanismes de maintien ont été mis en évidence. Le premier est un mécanisme de répétition subvocale, qui …
Development of vocal performance in 5th grade children - A longitudinal study of choral class singing
2009
The primary aim of the study was to assess the effects of choral class singing on vocal performance in primary school children. In particular, changes of the singing voice in terms of voice range profiles (VRP) and dysphonia severity index (DSI) were measured over the period of one school year. A further aim was to compare the effects of choral singing and regular music curriculum. A total of 50 5th-graders were assigned to two groups. Tuition of the choral singing group (n = 32) entailed a focus on singing in class as well as weekly 30-minute-sessions of special vocal training in small groups. Children in the regular music tuition group (n = 18), which also included singing, were given ext…
Singing as a form of vocal imitation - Mechanisms and deficits
2009
There has been a recent upsurge of interest in the neural and cognitive bases of inaccurate singing, commonly referred to as “tone deafness.” Explanations of this deficit have commonly focused on perceptual and motor functions. It is clear, however, that neither of these mechanisms can fully account for deficits in singing. We summarize the results of several studies concerning inaccurate, or “poor pitch” singing. Taken together, the results of these studies argue that the basis for singing-related deficits lies in the link between perception and action, rather than strictly motoric or perceptual factors. Moreover, singing deficits may involve general purpose vocal imitation mechanisms, rat…
miMic
2016
miMic, a sonic analogue of paper and pencil is proposed: An augmented microphone for vocal and gestural sonic sketching. Vocalizations are classified and interpreted as instances of sound models, which the user can play with by vocal and gestural control. The physical device is based on a modified microphone, with embedded inertial sensors and buttons. Sound models can be selected by vocal imitations that are automatically classified, and each model is mapped to vocal and gestural features for real-time control. With miMic, the sound designer can explore a vast sonic space and quickly produce expressive sonic sketches, which may be turned into sound prototypes by further adjustment of model…
