Abstract The paper describes methodology for creating a Slovak database of speech under stress and pilot observations. While the relationship between stress and speech characteristics can be utilized in a wide domain of speech technology applications, its research suffers from the lack of suitable databases, particularly in conversational speech. We propose a novel procedure to record acted speech in the home of actors and using their own smartphones. We describe both the collection of speech material under three levels of stress and the subsequent annotation of stress levels in this material. First observations suggest a reasonable inter-annotator agreement, as well as interesting avenues for the relationship between the intended stress levels and those perceived in speech.

Background: Obesity has long been recognized to have significant effect on respiratory functions. Many studies have reported exponential decrease in pulmonary function test (PFT) with increasing body mass index (BMI), which is a crude indicator of obesity. Also, the relationship between BMI and PFTs varies with age, race, geographical region and the different obesity standards used. To the best of our knowledge, not many studies have been done to examine the relationship between obesity and lung volumes among adults in our region, Jammu. This cross-sectional study was carried out with the objective of evaluating the effect of obesity on lung function test in obese but otherwise healthy adults of Jammu region.Methods: This cross-sectional study was conducted in Jammu region on subjects selected randomly from different colleges in the age group of 18-40 years. The study involved 300 subjects; divided into three groups of 100 each, based on BMI into normal, overweight and obese groups. Four respiratory parameters viz. FVC (Forced Vital Capacity), FEV1 (Forced Expiratory Volume in 1 second), FEV3 (Forced Expiratory Volume in 3 seconds), and MVV (Maximum Voluntary Ventilation) were used to assess their lung functions.Results: All the respiratory parameters exhibited statistically significant decrease in obese groups as compared to normal and overweight groups.Conclusions: The present study suggests that obesity alters the respiratory physiology by producing a restrictive ventilatory pattern.

During physiological spontaneous breathing maneuvers, the diaphragm displaces volume while maintaining curvature. However, with maximal diaphragm activation, curvature decreases sharply. We tested the hypotheses that the relationship between diaphragm muscle shortening and volume displacement (VD) is nonlinear and that curvature is a determinant of such a relationship. Radiopaque markers were surgically placed on three neighboring muscle fibers in the midcostal region of the diaphragm in six dogs. The three-dimensional locations were determined using biplanar fluoroscopy and diaphragm VD, curvature, and muscle shortening were computed in the prone and supine postures during spontaneous breathing (SB), spontaneous inspiration efforts after airway occlusion at lung volumes ranging from functional residual capacity (FRC) to total lung capacity, and during bilateral maximal phrenic nerve stimulation at those same lung volumes. In supine dogs, diaphragm VD was approximately two- to three-fold greater during maximal phrenic nerve stimulation than during SB. The contribution of muscle shortening to VD nonlinearly increases with level of diaphragm activation independent of posture. During submaximal diaphragm activation, the contribution is essentially linear due to constancy of diaphragm curvature in both the prone and supine posture. However, the sudden loss of curvature during maximal bilateral phrenic nerve stimulation at muscle shortening values greater than 40% (ΔL/LFRC) causes a nonlinear increase in the contribution of muscle shortening to diaphragm VD, which is concomitant with a nonlinear change in diaphragm curvature. We conclude that the nonlinear relationship between diaphragm muscle shortening and its VD is, in part, due to a loss of its curvature at extreme muscle shortening.

Purpose The aim of this study was to examine whether acoustic dysarthria characteristics align with overall motor profile in individuals with Parkinson's disease (PD). Potential speech differences between tremor-dominant and non–tremor-dominant subtypes are theoretically motivated but empirically inconclusive. Method Twenty-seven individuals with dysarthria from PD provided a contextual speech sample. Participants were grouped into non–tremor-dominant ( n = 12) and tremor-dominant ( n = 15) motor subtypes according to the Unified Parkinson Disease Rating Scale. Dependent speech variables included fundamental frequency range, average pause duration, cepstral peak prominence, stuttering dysfluencies, and maze dysfluencies. Results There were no significant differences between the speech of the tremor-dominant and non–tremor-dominant groups. High within-group variability existed across parameters and motor subtypes. Conclusion Speech characteristics across the areas of phonation, prosody, and fluency did not differ appreciably between PD motor subtypes.

Purpose: The goal of this study was to examine the effects of increases in vocal effort, without changing speech intensity, on respiratory and articulatory kinematics in young adults with typical voices. Method: A total of 10 participants completed a reading task under three speaking conditions: baseline, mild vocal effort, and maximum vocal effort. Respiratory inductance plethysmography bands around the chest and abdomen were used to estimate lung volumes during speech, and sensor coils for electromagnetic articulography were used to transduce articulatory movements, resulting in the following outcome measures: lung volume at speech initiation (LVSI) and at speech termination (LVST), articulatory kinematic vowel space (AKVS) of two points on the tongue dorsum (body and blade), and lip aperture. Results: With increases in vocal effort, and no statistical changes in speech intensity, speakers showed: (a) no statistically significant differences in LVST, (b) statistically significant increases in LVSI, (c) no statistically significant differences in AKVS measures, and (d) statistically significant reductions in lip aperture. Conclusions: Speakers with typical voices exhibited larger lung volumes at speech initiation during increases in vocal effort, paired with reduced lip displacements. To our knowledge, this is the first study to demonstrate evidence that articulatory kinematics are impacted by modulations in vocal effort. However, the mechanisms underlying vocal effort may differ between speakers with and without voice disorders. Thus, future work should examine the relationship between articulatory kinematics, respiratory kinematics, and laryngeal-level changes during vocal effort in speakers with and without voice disorders.

We related diaphragm electromyographic activity (Edi) to transdiaphragmatic pressure (Pdi) in man during graded inspiratory efforts. Estimates of rib cage and abdominal volume displacements were based on their anteroposterior (AP) diameter changes. The diaphragm was assumed to contract isometrically when subjects performed inspiratory efforts against a closed airway at specified abdominothoracic configurations, increasing Edi and Pdi while holding lung volume and rib case and abdominal AP diameters constant. The relationship between Pdi and Edi depends primarily on abdominothoracic configuration rather than lung volume. For equal increments in lung volume, the Pdi developed at constant Edi is four to eight times more sensitive to changes in abdominal than in rib cage AP diameter. We demonstrate an isofunctional state of the diaphragm at different lung volumes, when increases in lung volume and rib cage AP diameter are compensated for by slight decreases in abdominal AP diameter, resulting in a constant relationship between Edi and Pdi. We conclude that diaphragm shortening is reflected more directly in abdominal displacement than in lung volume change.

Objective: To address two questions of theoretical importance regarding the profile and course of communication impairment associated with velocardiofacial syndrome (VCFS): (1) do speech characteristics of children with VCFS differ from a group of children with some of the phenotypic characteristics of VCFS who do not have the syndrome, and (2) do younger children with VCFS demonstrate speech patterns that differ from older children with VCFS? Design: Prospective, cross-sectional study comparing two groups of children at two age levels. Patients: Thirteen children with VCFS and eight children with some of the phenotypic features of VCFS who did not have the syndrome. Children ranged in age from 3 to 10 years. Main Outcome Measure: (1) Broad phonetic transcription of speech yielding measures of number of consonant types, Percent Consonant Correct, and percentage of glottal stops used; and (2) composite ratings of velopharyngeal function made from perceptual, aerodynamic, and endoscopic evaluations. Results: Younger children with VCFS demonstrated greater speech impairment than older children with VCFS or the children without VCFS, such as smaller consonant inventories, greater number of developmental errors, greater severity of articulation disorder, and higher frequency of glottal stop use. The relationship between ratings of velopharyngeal function and the speech variables analyzed was not straightforward. Conclusions: Some young children with VCFS demonstrated speech impairment that is qualitatively and quantitatively different from older children with VCFS or children without VCFS. This finding supports the hypothesis that some children with VCFS demonstrate a profile of speech production that is different from normal but also may be specific to the syndrome.

To assess the effects of lung volume and chest wall configuration on electromechanical coupling of the abdominal muscles, we examined the relationship between abdominal muscle pressure ( Pmus ) and electrical activity ( EMGab ) in eight normal subjects during expiratory efforts at lung volumes ranging from functional residual capacity (FRC) to FRC + 2.0 liters. At and above FRC, increases of lung volume did not significantly alter either the Pmus - EMGab relationship or abdominal surface linear dimensions, although expiratory efforts displaced the abdomen inward from its relaxed position. We attribute the constancy of delta Pmus /delta EMG above FRC to the negligible effects of increasing lung volume on abdominal configuration and muscle length. Expiratory efforts performed at lung volumes below FRC resulted in a wider range of abdominal indrawing . Under these conditions the EMGab required to augment Pmus by 30–40 cmH2O increased as the abdomen was displaced inward. This decrease of delta Pmus /delta EMGab appears to reflect muscle shortening, flattening of the abdominal wall, and possibly deformation of the rib cage.

Six 3-year-old language-disordered children were taught the relationship between semantic role and word order through either production or comprehension training. All 6 subjects successfully learned the relationship through production training as indicated by their responses to a production probe and by their use of word order to express semantic role distinctions in their conversational speech. These subjects never used word order cues to decode semantically reversible sentences on comprehension tests even after they were using word order appropriately in their conversational speech. Also, none of the subjects were able to learn word order through comprehension training. The results were interpreted to mean the subjects could learn a word-order rule by teaching them to say sentences that contrast word order and meaning but that they could not learn by being taught to respond to sentences. The problem with this latter procedure may be that it requires a mental operation that is beyond the level of cognitive development of children under the age of 4.

In the article, on the material of Ivan Turgenev’s library and his short story “The Jew”, the issue of reading and creative perception is examined. Turgenev’s perception of Ivanhoe by Walter Scott is in the focus. The research attention is developing from the interpretation of several Turgenev’s notes left in the English version of the novel to the analysis of the creative perception of the images of Isaac and Rebecca, which became the ideological and semantic basis of “The Jew”. The reading of Ivanhoe in the original in the early 1840s became for the writer a penetration into Scott’s individual writing system. Turgenev’s few notes indicate that he became acquainted with Scott’s creative manner: the ability to voluminously weave comic elements into the pathetic-heroic atmosphere of action, the combination of historical and artistic material, the boldness of the ironic tone, and the mastery of speech characteristics. The reader’s perception of Scott’s novel was soon replaced by its creative interpretation, as a result of which “The Jew” appeared. Following the example of the English novelist, the object of Turgenev’s artistic reflection is a Jewish father and his daughter, who find themselves in a socio-historical and moral-psychological crisis — the Patriotic War of 1812 and the Foreign Campaigns of the Russian Army. There is an obvious similarity between Scott’s Rebecca and Turgenev’s Sarah: from the elements of the external description and the details of the portrait to the moral and psychological characteristics. The two young girls are especially united by the sense of pride and the awareness of their dignity, which clearly manifest themselves in the moments of danger that threatens them. Besides, the relationship between the Jewish girl and the Russian officer in Turgenev’s story vaguely resembles the situation of Rebecca and Ivanhoe. But the love line in “The Jew” does not develop in full. Considering William Shakespeare’s and Gotthold Lessing’s experience, following Walter Scott, Turgenev reflects on the universal nature of the “humiliated tribe”. The Russian writer depicts the psychology of the experiences of the Jew Girshel, accused of spying for the French. In the tradition of objectivity and epic literature, inherited from Scott, Turgenev draws a tragic line related to the position of an ordinary person. But, unlike the English novelist, Turgenev brings the torment of the character to the highest limit – the death penalty. At the same time, the Russian writer explicates sharp contradictions in the image of his character that turns out to be a carrier of suffering, on the one hand, and a source of laughter, on the other. This shows Turgenev’s orientation on the features of Shakespeare’s image of a person, in which the tragic invariably coexists with the comic. Walter Scott sensitively learned the law of ambivalence from Shakespeare, too.
