To introduce the conceptual, theoretical, and practical foundations of a novel approach to voice therapy, called conversation training therapy (CTT), which focuses exclusively on voice awareness and efficient voice production in patient-driven conversational narrative, without the use of a traditional therapeutic hierarchy. CTT is grounded in motor learning theory, focused on training target voice goals in spontaneous, conversational speech in the first session and throughout. CTT was developed by a consensus panel of expert clinical voice-specialized speech-language pathologists (SLPs) and patients with voice problems.

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.

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.

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.

The purpose of this project was to determine the spectral and electroglottograph (EGG) differences exhibited by classically trained female singers when singing through their primo passaggio. The hypotheses were that the singers would exhibit relatively steady EGG levels and minimal changes in speech spectra when singing through their primo passaggio. It also was hypothesized that EGG and spectral measurements at the crest and trough of the vibrato cycles would be similar to each other.

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.

A cecum-like protrusion of the pharynx (the laryngeal cecum or vestibular recess [VR]) develops immediately anterior to the laryngeal part of the respiratory diverticulum. An expansion of the VR has been well described, whereas the fate of the diverticulum is still obscure, although its pharyngeal opening corresponds to the glottis. We observed sagittal sections of 10 embryos (five specimens at 5–6 weeks and another five at 7–8 weeks) and eight fetuses at 25–30 weeks. At 5–6 weeks, a lumen of the laryngeal part of the respiratory diverticulum appeared, and subsequently, the VR opened into the epithelial lamina.

A customized mechanical tester that slices thin, soft samples was used to measure the fracture toughness of vocal fold tissue. Porcine vocal fold lamina propria was subjected to quasi-static, guillotine-like tests at three equally distanced regions along the anterior-posterior direction. The central one-third where high-velocity collisions between vocal folds occur was found to have the maximum fracture toughness. In contrast, the anterior one-third featured a lower toughness. Fracture toughness can be indicative of the risk of benign and malignant lesions in vocal fold tissue.

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.

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.

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.

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.

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.
Staffan Björklund, Johan Sundberg, 2015-08-16 20:04:41 PM
Subglottal pressure (Ps) is strongly correlated with sound pressure level (SPL) and is easy to measure by means of commonly available equipment. The SPL/Ps ratio is strongly dependent on the efficiency of the phonatory apparatus and should be of great relevance to clinical practice. However, published normative data are still missing.

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.

This experimental study investigated the back pressure (Pback) versus flow (U) relationship for 10 different tubes commonly used for semi-occluded vocal tract exercises, that is, eight straws of different lengths and diameters, a resonance tube, and a silicone tube similar to a Lax Vox tube. All tubes were assessed with the free end in air. The resonance tube and silicone tube were further assessed with the free end under water at the depths from 1 to 7 cm in steps of 1 cm. The results showed that relative changes in the diameter of straws affect Pback considerably more compared with the same amount of relative change in length.

This article reports three studies about performance of lieder, and in particular in comparison with opera performance. 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.

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.

Spasmodic dysphonia (SD) is a rare but often debilitating disease. Due to lack of awareness among practitioners and lack of well-defined diagnostic criteria, it can be difficult for patients with SD to receive a diagnosis and subsequent treatment. There is currently no literature documenting the efficacy of the medical community in recognizing and diagnosing this disorder. We aimed to quantify the patients' experiences with obtaining a diagnosis of SD.

A well-functioning voice is becoming increasingly important because voice-demanding professions are increasing. The largest proportion of voice disorders is caused by factors in the environment. Moisture damage is common and can initiate microbial growth and/or diffusion of chemicals from building materials. Indoor air problems due to moisture damage are associated with a number of health symptoms, for example, rhinitis, cough, and asthma symptoms. The purpose of this study was to investigate if children attending a day care center, preschool, or school with indoor air problems due to moisture damage were hoarse more often than the children in a control group.

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.

Although an association between psychosocial distress (depression, anxiety, somatization, and perceived stress) and voice disorders has been observed, little is known about the relationship between distress and patient-reported voice handicap. Furthermore, the psychological mechanisms underlying this relationship are poorly understood. Perceived control plays an important role in distress associated with other medical disorders. The objectives of this study were to (1) characterize the relationship between distress and patient-reported voice handicap and (2) examine the role of perceived control in this relationship.

The purpose of this study was to determine the impact of vagal nerve stimulation (VNS) on the vocal quality using the dysphonia severity index (DSI). It was hypothesized that the objective vocal quality and other vocal characteristics are disordered in comparison with an age- and gender-matched control group. In addition, the acoustic vocal parameters were compared during three conditions: at rest, during normal stimulation, and raised stimulation. A significant relation between the amount of stimulation and the presence of disturbed acoustic parameters was hypothesized.

The cepstral measures are gaining attention in the voice analysis as it is reported to be strong predictor of voice impairments. As singer's voice is reported to be present with more harmonics, it can be hypothesized that there would be an increase in the value of cepstral parameters. Also, little is known about the cepstral characteristics of voices in Indian classical Carnatic singers; and hence, the present study was undertaken with an aim to characterize the singer's voice using cepstral measures.

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).

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.

Inhaled steroids are widely used for persistent cough treatment. Although the side effects of long-term inhaled steroids have been well described in the literature, their laryngeal side effects after short-term use have not yet been defined. The aim of this study was to evaluate the effect of 1 month application of inhaled steroid treatment on voice parameters in patients with subacute or chronic cough. Furthermore, the efficacy of inhaled steroids on cough was investigated, as well.

The learning and teaching of different singing styles, such as operatic and Chinese folk singing, was often found to be very challenging in professional music education because of the complexity of varied musical properties and vocalizations. By studying the acoustical and musical parameters of the singing voice, this study identified distinctive tuning characteristics of a particular folk music in China—Hua'er music—to inform the ineffective folk singing practices, which were hampered by the neglect of inherent tuning issues in music.

The purpose of this study was to provide a preliminary acoustic reference for an elderly population (aged 60–80) with perceptually normal voices to determine the degree of noise in the vocal signal of this population; a younger population (aged 20–30) with perceptually normal voices participated for comparison. The participants were tested on the MultidimensionalVoice Program (model 5105, KayPENTAX, Lincoln Park, NJ), and the following acoustic parameters were evaluated: relative average perturbation (cycle-to-cycle frequency perturbations), shimmer (cycle-to-cycle amplitude perturbations), and noise-to-harmonic ratio (degree of noise in the vocal signal).

In-office laryngeal procedures present an alternative to the risks and costs associated with general anesthesia. However, the inherent control afforded by the operative theater is decreased potentially increasing the risk of complications. Many patients undergoing these procedures have traditional surgical risk factors, such as antithrombotic (AT) medical therapy. We sought to quantify complication rates for in-office procedures as a function of AT therapy.

Vocal fold paralysis can have an important impact on a patient's quality of life. The goal of this study was to compare, in terms of vocal improvement and motility recovery, the post-vocal treatment results of our patients with unilateral vocal fold paralysis (UVFP) when treatment was started early (within 4 weeks from injury) versus intermediate (from 4 to 8 weeks) or delayed (at least 8 weeks after injury) treatment.
