Vít Hampala, Maxime Garcia, Jan G. Švec, Ronald C. Scherer, Christian T. Herbst, 2015-08-16 20:04:41 PM
Electroglottography (EGG) is a widely used noninvasive method that purports to measure changes in relative vocal fold contact area (VFCA) during phonation. Despite its broad application, the putative direct relation between the EGG waveform and VFCA has to date only been formally tested in a single study, suggesting an approximately linear relationship. However, in that study, flow-induced vocal fold (VF) vibration was not investigated. A rigorous empirical evaluation of EGG as a measure of VFCA under proper physiological conditions is therefore still needed.Magnetic Control of the Glottic Opening in an Sheep Larynx Model: A Preliminary Study
Zafer Ciftci, Mahmut Deniz, Halide Gunes Ciftci, Damla Nihan Ozdemir, Aklime Isik, Erdogan Gultekin, 2015-08-16 20:04:41 PM
So far, a number of techniques have been described for the treatment of bilateral vocal fold paralysis. These techniques were reported to be successful in maintaining an adequate airway but also found to be associated with an increased risk of aspiration, dysphonia, and granulation tissue formation at the operation site. We aimed to investigate the effectiveness of a novel mucosa-sparing technique based on the generation of a magnetic field within the larynx for the tailored lateralization of the ipsilateral vocal fold.Refractory Dysphonia Due to Isolated Cricothyroid Muscle Dystonia

Laryngeal videokymography and high-speed digital kymography are the currently available techniques for studying aperiodic vibration of the vocal folds. However, videokymography has a fundamental limitation that only linear portions of the vocal fold mucosa can be visualized, whereas high-speed digital kymography has the disadvantages of lack of immediate feedback during examination and considerable waiting time before kymographic visualization. We developed a new system, two-dimensional (2D) scanning videokymography, that provides a possible alternative for evaluation of the vibratory pattern of the vocal folds.Normative Values and Interrelationship of MDVP Voice Analysis Parameters Before and After Endotracheal Intubation

Ingo R. Titze, Lynn Maxfield, Anil Palaparthi, 2015-08-16 20:04:41 PM
Voice production is an inefficient process in terms of energy expended versus acoustic energy produced. A traditional efficiency measure, glottal efficiency, relates acoustic power radiated from the mouth to aerodynamic power produced in the trachea. This efficiency ranges between 0.0001% and 1.0%. It involves lung pressure and hence would appear to be a useful effort measure for a given acoustic output. Difficulty in the combined measurement of lung pressure and tracheal airflow, however, has impeded clinical application of glottal efficiency.Effect of Spinal Manipulative Therapy on the Singing Voice

Onur Ismi, Rabia Bozdogan Arpaci, Tugce Puturgeli, Cengiz Ozcan, Kemal Gorur, 2015-08-16 20:04:41 PM
Leiomyosarcomas (LMSs) are malignant tumors of smooth muscles accounting for 5–6% of all soft tissue sarcomas. They are mostly seen in the gastrointestinal tractus, the uterus, and the retroperitoneum. Soft tissue sarcomas comprise <1% of all laryngeal malignancies, most of which are chondrosarcomas. Laryngeal LMSs are rarely seen malignancies, which are published as case reports. We presented a case of laryngeal LMS, which was seen 4 years later in a laryngeal squamous cell carcinoma patient who underwent laryngeal laser microsurgery.The Americans With Disabilities Act and Voice Disorders: Practical Guidelines for Voice Clinicians
Derek Isetti, Tanya Eadie, 2015-08-16 20:04:41 PM
The Americans with Disabilities Act Amendments Act of 2008 (ADAAA) resulted in changes to the legal definition of disability and substantially affected how those with voice disorders may qualify for reasonable accommodations under the law. However, there has been little guidance and a lack of awareness about these changes within the voice literature.

Mami Kaneko, Shigeru Hirano, Ichiro Tateya, Yo Kishimoto, Nao Hiwatashi, Masako Fujiu-Kurachi, Juichi Ito, 2015-08-16 20:04:41 PM
Age-related voice change is characterized as weak, harsh, and breathy. These changes are caused by histologic alteration of the lamina propria of the vocal fold mucosa as well as atrophy of the thyroarytenoid muscle. Several therapeutic strategies involving laryngeal framework surgery and injection laryngoplasty have been tried, but effects have been limited. Vocal function exercises (VFE) have been used to treat age-related vocal fold atrophy although the effectiveness has been shown with limited analysis.Influence of and Sequence Length of Audio and Electroglottographic Signals on Perturbation Measures for Voice Assessment
Julian Hohm, Michael Döllinger, Christopher Bohr, Stefan Kniesburges, Anke Ziethe, 2015-08-16 20:04:41 PM
Within the functional assessment of voice disorders, an objective analysis of measured parameters from audio, electroglottographic (EGG), or visual signals is desired. In a typical clinical situation, reliable objective analysis is not always possible due to missing standardization and unknown stability of the clinical parameters. The aim of this study was to investigate the robustness/stability of measured clinical parameters of the audio and EGG signals in a typical clinical setting to ensure a reliable objective analysis.Voice Onset Time for the Word-Initial Voiceless Consonant /t/ in Japanese Spasmodic Dysphonia—A Comparison With Normal Controls

Christian T. Herbst, Markus Hess, Frank Müller, Jan G. Švec, Johan Sundberg, 2015-08-16 20:04:41 PM
Previous research suggests that independent variation of vocal loudness and glottal configuration (type and degree of vocal fold adduction) does not occur in untrained speech production. This study investigated whether these factors can be varied independently in trained singing and how subglottal pressure is related to average glottal airflow, voice source properties, and sound level under these conditions. A classically trained baritone produced sustained phonations on the endoscopic vowel [i:] at pitch D4 (approximately 294 Hz), exclusively varying either (a) vocal register; (b) phonation type (from "breathy" to "pressed" via cartilaginous adduction); or (c) vocal loudness, while keeping the others constant.Evaluation of Singer's Voice Quality by Means of Visual Pattern Recognition
Paweł Forczmański, 2015-08-16 20:04:41 PM
The article presents a description of the algorithm of singing voice quality assessment that uses selected methods from the field of digital image processing and recognition. It adopts the assumption that an audio signal with recorded vocal exercise can be converted into a visual representation, and processed further, as an image. Presented approach is based on generating a sound spectrogram of a sample in the form of a rectangular matrix, objective improvement of its visual quality based on local changes in brightness and contrast, and scaling to a fixed size.Relationship Between Subglottal Pressure and Sound Pressure Level in Untrained Voices

Manuj Yadav, Densil Cabrera, Dianna T. Kenny, 2015-08-16 20:04:41 PM
Messa di voce (MDV) is a singing exercise that involves sustaining a single pitch with a linear change in loudness from silence to maximum intensity (the crescendo part) and back to silence again (the decrescendo part), with time symmetry between the two parts. Previous studies have used the sound pressure level (SPL, in decibels) of a singer's voice to measure loudness, so as to assess the linearity of each part—an approach that has limitations due to loudness and SPL not being linearly related.Descriptive Epidemiology of Voice Disorders in Rheumatoid Arthritis: Prevalence, Risk Factors, and Quality of Life Burden

In study 1, 21 participants with experience in music performance and teaching completed a survey concerning various characteristics of lieder performance. The results showed that there was consensus between the literature and the assessment of an expert panel—that a "natural" and "unoperatic" vibrato was favored, and that diction, text, and variation of tone are all important aspects of lieder performance.Atypical Presentation of a Common Disease: Shingles of the Larynx
Sarah Hosseini, Faisal Zawawi, Jonathan Young, 2015-08-16 20:04:41 PM
Herpes zoster is a neurocutaneous disease resulting from the reactivation of endogenous varicella-zoster virus (VZV) in dorsal sensory or cranial nerve ganglia. Rarely, this infection manifests without the characteristic dermatomal rash, a condition termed zoster sine herpete. Viral spreading of herpes zoster in the head and neck may manifest as various signs and symptoms because of the multiple possible combinations of cranial neuropathies. With only six cases reported in the English literature up to now, isolated neuropathies of the vagus nerve in the absence of cutaneous lesions tend to be misdiagnosed as idiopathic laryngeal paralysis.An Acoustic and Electroglottographic Study of the Aging Voice With and Without an Open Jaw Posture

Michael S. Benninger, Andrea Hanick, Douglas M. Hicks, 2015-08-16 20:04:41 PM
Bilateral vocal fold paralysis most commonly results from iatrogenic trauma to the recurrent laryngeal nerve during surgical procedures in the anterior neck. Patients may require tracheostomy because of acute or gradual onset of dyspnea and airway compromise. The intralaryngeal injection of Botox has been considered as a possible therapy for these airway symptoms of bilateral vocal fold paralysis. Chronic unopposed activity of intact cricothyroid muscles could potentially result in gradual medialization of the vocal folds in patients with bilateral recurrent laryngeal nerve paralysis.Vocal Hygiene Habits and Vocal Handicap Among Conservatory Students of Classical Singing

Ben C. Watson, R.J. Baken, Rick M. Roark, 2015-08-16 20:04:41 PM
Vocal attack time (VAT) is the time lag between the growth of sound pressure (SP) and electroglottographic (EGG) signals at vocal initiation. The characteristics of voice initiation are associated with issues of vocal hygiene, efficiency, and quality. Vocal onsets have commonly been qualitatively characterized into three types: hard, simultaneous, and breathy. This study examines the effect of voice onset type on VAT values in normal speakers. SP and EGG recordings were obtained for 55 female and 57 male subjects while producing multiple tokens of three tasks (sustained /ɑ/ and "always" as unaspirated onsets, and "hallways" as an aspirated onset).Temporal Variables in Voice Therapy

Emily Duke, Laura W. Plexico, Mary J. Sandage, Matthew Hoch, 2015-08-16 20:04:41 PM
This study investigated the effect of traditional vocal warm-up versus semioccluded vocal tract exercises on the acoustic parameters of voice through three questions: does vocal warm-up condition significantly alter the singing power ratio of the singing voice? Is singing power ratio dependent upon vowel? Is perceived phonatory effort affected by warm-up condition? Hypotheses were that vocal warm-up would alter the singing power ratio, and that semioccluded vocal tract warm-up would affect the singing power ratio more than no warm-up or traditional warm-up, that singing power ratio would vary across vowel, and that perceived phonatory effort would vary with warm-up condition.Vocal Fold Adjustment Caused by Phonation Into a Tube: A Double-Case Study Using Computed Tomography
