This study explored the role of transglottal pressure on the lowering of vocal fundamental frequency (Fo-lowering) during voiced plosive/b/ production. The subjects were 3 males and 3 females. Magnitudes of Fo-lowering were recorded under two different conditions: 1) when the vocal tract was abruptly interrupted during sustained phonation, and 2) when/i: bi: /was uttered. There was no consistent relation between the magnitudes of Fo-lowerings obtained under these two different conditions. In other words, Fo-lowering during /b/ production could not be explained by changes of transglottal pressure only. This implyies positive participation of the laryngeal muscles in the mechanism of Fo-lowering. © 1993, The Japan Society of Logopedics and Phoniatrics. All rights reserved.

Etude des adductions/abductions totales et partielles des cordes vocales

January 2006

In this study, we have shown that, in the intervocalic position, simple and geminate voiceless plosives (t tt), present a total abduction of the vocal folds (anterior+posterior parts). While their voiceless emphatic (or uvularized) counterparts (T TT) are produced with an anterior abduction only. Simple and geminate voiced plosives also show a slight anterior abduction which is longer during ... [Show full abstract] geminate, and shorter during (). Arguments have been presented showing that the anterior abductions observed during (T TT) and voiced plosives are passive, due to the increase of the intraoral pressure. (i) falsetto shows a slight abduction of the vocal folds that we assign to the action of the intrinsic laryngeal muscles.

Effects of Adductor Muscle Stimulation on Speech in Abductor Spasmodic Dysphonia

November 2000 · The Laryngoscope

Objective: To determine whether adductor laryngeal muscle stimulation might be a beneficial treatment alternative for abductor spasmodic dysphonia (ABSD). Study design: Baseline comparisons were made on measures of voiceless consonant and syllable duration between patients with ABSD and normal control subjects, and speech and voice production with and without muscle stimulation were compared ... [Show full abstract] within 10 patients with ABSD. Methods: Baseline group comparisons were conducted on measures of syllable and voiceless consonant duration between the patients and the control subjects. Neuromuscular stimulation was applied to the thyroarytenoid or lateral cricoarytenoid muscles in the patients during extended phonation, and measures were made of fundamental frequency and sound pressure level in the stimulated and nonstimulated conditions. Voiceless consonant duration was compared with and without adductor laryngeal muscle stimulation during syllable repetitions and sentences in the patients. Results: Before stimulation, the patients had increased syllable durations in comparison with control subjects (P = .003). Repeated within-patient comparisons with and without stimulation demonstrated significant (P < .008) reductions in voiceless consonant durations during syllable repetition. The more severely affected patients had the greatest reductions in voiceless consonant duration during sentence production. Conclusions: Adductor muscle stimulation improved speech production in patients with ABSD, and the improvement was greatest in the most severely affected patients. Therefore adductor muscle stimulation has potential for benefiting patients with ABSD.

Self-Excitation Vocalization Analyses of Vocal Chord Under Breathing Flow and Wide Frequency Change...

January 2002

This paper presents some analyses and experiments on vocalizing mechanics in vocal chord due to the breathing flow, and their wide range of frequency change by varing the interior muscle activations. Three dimensional dynamic response of the hyperelastic and finite deformation body of the vocal chord and the interior muscles have been analysed at first and the exclusive FEM system has been ... [Show full abstract] developed. The eigen frequencies and vibration characteristics of the vocal chord are analysed by varing the activation level of the interior muscles. The Helmholtz equation of the breathing flow under transient state has been analysed to obtain the pressure pulsation characteristics behind the vocal chord during vocalizing of the source voice. Combining both approaches stated aboves, the mechanics of the self-exciting vibration of the vocal chord have been studied in detail using the root-locus approach. It is also found in the analysis and experiments that the frequency of the self-exciting vibration can be widely varied with the activation level of the interior muscle of the vocal chord, giving rise to a variety of frequency level of the source voice.

Role of the Thyroarytenoid Muscle in Regulation of Fundamental Frequency

September 1989 · Journal of Voice

Thyroarytenoid muscle activity is shown to combine with cricothyroid muscle activity to regulate fundamental frequency of phonation. The relative amount of activity in these muscles, as measured electromyographically, is illustrated on a muscle activation plot (MAP) for four subjects vocalizing at different pitches and loudnesses. Electrical stimulation of the thyroarytenoid muscle in various ... [Show full abstract] regions of the MAP suggests that both positive and negative changes in fundamental frequency (F0) can occur with increased thyroarytenoid activity. At lower fundamental frequencies and lower vocal intensities, F0 correlates positively with thyroarytenoid activity, but at higher fundamental frequencies and low intensity (especially in falsetto voice) an increase in thyroarytenoid activity tends to lower F0. A biomechanical body-cover model of fundamental frequency control is used to explain this phenomenon.

Effects of a Semioccluded Vocal Tract on Laryngeal Muscle Activity and Glottal Adduction in a Single...

December 2008 · Folia Phoniatrica et Logopaedica

Voice training exploits semiocclusives, which increase vocal tract interaction with the source. Modeling results suggest that vocal economy (maximum flow declination rate divided by maximum area declination rate, MADR) is improved by matching the glottal and vocal tract impedances. Changes in MADR may be correlated with thyroarytenoid (TA) muscle activity. Here the effects of impedance matching ... [Show full abstract] are studied for laryngeal muscle activity and glottal resistance. One female repeated [pa:p:a] before and immediately after (a) phonation into different-sized tubes and (b) voiced bilabial fricative [beta:]. To allow estimation of subglottic pressure from the oral pressure, [p] was inserted also in the repetitions of the semiocclusions. Airflow was registered using a flow mask. EMG was registered from TA, cricothyroid (CT) and lateral cricoarytenoid (LCA) muscles. Phonation was simulated using a 7 x 5 x 5 point-mass model of the vocal folds, allowing inputs of simulated laryngeal muscle activation. The variables were TA, CT and LCA activities. Increased vocal tract impedance caused the subject to raise TA activity compared to CT and LCA activities. Computer simulation showed that higher glottal economy and efficiency (oral radiated power divided by aerodynamic power) were obtained with a higher TA/CT ratio when LCA activity was tuned for ideal adduction.

Pump function curve shape for a model lymphatic vessel

May 2016 · Medical Engineering & Physics

The transport capacity of a contractile segment of lymphatic vessel is defined by its pump function curve relating mean flow-rate and adverse pressure difference. Numerous system characteristics affect curve shape and the magnitude of the generated flow-rates and pressures. Some cannot be varied experimentally, but their separate and interacting effects can be systematically revealed numerically. ... [Show full abstract] This paper explores variations in the rate of change of active tension and the form of the relation between active tension and muscle length, factors not known from experiment to functional precision. Whether the pump function curve bends toward or away from the origin depends partly on the curvature of the passive pressure–diameter relation near zero transmural pressure, but rather more on the form of the relation between active tension and muscle length. A pump function curve bending away from the origin defines a well-performing pump by maximum steady output power. This behaviour is favoured by a length/active-tension relationship which sustains tension at smaller lengths. Such a relationship also favours high peak mechanical efficiency, defined as output power divided by the input power obtained from the lymphangion diameter changes and active-tension time-course. The results highlight the need to pin down experimentally the form of the length/active-tension relationship.

Nationwide Survey of Spasmodic Dysphonia in Japan

February 2016 · The Japan Journal of Logopedics and Phoniatrics

We conducted a nationwide survey of spasmodic dysphonia (SD) in Japan with the aim of revealing the epidemiological and clinical features of SD. Questionnaires were sent to 655 major otolaryngological institutions with a data disc which included representative voice samples of SD. We identified 1,534 patients over a period of 2 years. Among them, 887 (0.77 patient/100,000 population) were new ... [Show full abstract] patients. Prevalence of the disease in Japan was estimated to be 3.5-7.0 patients/100,000 population. The patients were predominantly 20-39 years in age (59.0%) and female in gender (1: 4.1 male/female ratio). Adductor type accounted for 93.2% of the patients. Clinical symptoms were characterized by strangled or effortful speech in the adductor type, and whispered or breathy voice quality in the abductor type. The median interval between the onset of symptoms and the first hospital visit was 3.0 years. Treatments by botulinum toxin injection into the intrinsic laryngeal muscles or type 2 thyroplasty were aggregately performed at several hospitals. This study suggested that SD is not yet fully recognized even among otolaryngologists and that diagnostic criteria and a standard therapeutic guideline need to be established.
