Introduction: Voice is a determining factor for transgender women to be able to communicate and be recognized by the other as belonging to the desired gender. In voice clinic, exercises of semi-occluded vocal tract and technological resources that act in an adjunct manner are used, aiming to promote better phonatory adjustments, raising the fundamental frequency and vocal tract adjustments such as resonance, intensity, articulation, speed, among others. The work of the speech therapist requires an expanded vision, seeking the integration between voice and body. The present study seeks to understand how the modulation process for acute pitch occurs upon using exercise with a high-strength tube associated with the therapeutic resource of low intensity laser, aiming to evaluate the effectiveness of these two tools when used simultaneously. Material and Methods: The research was based on a case study of a transgender woman. The therapy was based on the application of low intensity laser associated with the use of exercise with high strength tube. The study was approved by the Research Ethics Committee and the participant signed the Informed Consent Form. Anamnesis, application of the Transsexual Voice Questionnaire (TVQ) and evaluation before and after the application of the techniques were performed, through acoustic analysis of the vocal signal and auditory-perceptive evaluation, through the Vocal Profile Analysis (VPA) Protocol. Results and Discussion: There was an increase in variability in the categories of pitch and loudness, absence of crackling and improvement in energy distribution after therapy. The patient used greater voice breathing and there was a predominance in the distribution of articulatory adjustments. Conclusion: Speech therapy promoted an election of the vocal pitch, modified the characteristics of vocal quality and dynamics and generated a sound fluency for the female. It was possible to observe that the greatest change occurred in an auditory way, interfering in the acoustic impression that the other has in relation to this voice, that is, the greatest gain was in the sound filter

Aim of study: Evaluation of the speech therapy on voice quality in patients with unilateral vocal fold palsy. Material and methods: The study group included 11 patients, 8 women and 3 men, in age between 16 to 72 years, with unilateral vocal fold palsy, diagnosed in ENT Department of Warsaw Medical University between 2017-2018. Each person completed questionnaires: the voice disability self-assessment scale (VHI), the voice-based quality of life (VRQoL) scale, the vocal tract discomfort scale (VTD). All questionnaires were completed twice, before and after the voice therapy. In addition, the acoustic analysis of the voice, the assessment of the maximum phonation time and the breathing tract were performed twice in each patient. Each of the patients had a voice rehabilitation consisting of a series of 10 meetings. Results: Statistical analysis of the results of maximum phonation time, the self-assessment of voice disability, the quality of life depending on the voice, discomfort of the vocal tract voice acoustic analysis showed statistically significant differences in the results before and after rehabilitation (p <0.005). In addition, the improvement of the respiratory tract was observed in the majority of patients. Conclusions: Speech therapy significantly affects the voice quality of patients with unilateral laryngeal nerve palsy.

Many studies in language acquisition have addressed consonant/vowel co-occurrence, henceforth CV. Traditional views focus on the upper vocal tract, while a recent one stresses the importance of its lower end. None has nevertheless attempted to understand how these two tracts interact and cooperate in early vocalization. The role of the ambient language in this interaction is also understudied. The aim of this paper is to integrate such apparently contradictory views by observing activity in the entire vocal tract during the emergence of CV combinations in three Brazilian children interacting with their parents between the ages of 0:06 and 1:07. We have used a mixed longitudinal and cross-sectional method, whereby one child was followed longitudinally while the other two were observed at later, complementary stages. Data were collected using a digital recorder, transcribed with the aid of acoustic analysis, and later processed with a syllable counter. Our results uncovered the following trends: biomechanical constraints interact with ambient language inluences; control over articulations is diferent for vowels and consonants; infants tend to have a favorite babbling vowel; the lower vocal tract remains active past 12 months; and not all children acquire articulatory control in the same way. Overall, they do not support any speciic view, but, rather, call for the integration of several separate strands in the literature.

Purpose Semi-occluded vocal tract (SOVT) exercises with tubes or straws have been widely used for a variety of voice disorders. Yet, the effects of longer periods of SOVT exercises (lasting for weeks) on the aging voice are not well understood. This study investigated the effects of a 6-week straw phonation in water (SPW) exercise program. Method Thirty-seven elderly subjects with self-perceived voice problems were assigned into two groups: (a) SPW exercises with six weekly sessions and home practice (experimental group) and (b) vocal hygiene education (control group). Before and after intervention (2 weeks after the completion of the exercise program), acoustic analysis, auditory–perceptual evaluation, and self-assessment of vocal impairment were conducted. Results Analysis of covariance revealed significant differences between the two groups in smoothed cepstral peak prominence measures, harmonics-to-noise ratio, the auditory–perceptual parameter of breathiness, and Voice Handicap Index-10 scores postintervention. No significant differences between the two groups were found for other measures. Conclusions Our results supported the positive effects of SOVT exercises for the aging voice, with a 6-week SPW exercise program being a clinical option. Future studies should involve long-term follow-up and additional outcome measures to better understand the efficacy of SOVT exercises, particularly SPW exercises, for the aging voice.

A clinical and immunological examination of 140 women with verified cipher B 37.3-inflammatory disease caused by yeast-like fungi of the genus Candida, characterized by the presence of 4 or more episodes during the year, is carried out. Before the start of therapy, an imbalance of cellular and humoral factors of innate immunity, the content of cytokines in the vaginal secretion, was detected. The optical radiation of a low-intensity laser was included in the scheme of therapeutic measures, starting from the first day of treatment. The results of the study demonstrate that local exposure on the vulva and vagina with laser radiation with a wavelength of 635 nm, with the power of 5 mW, for 10 minutes per area for a 10-day period reliably reduce the severity of objective and subjective symptoms of vaginal candidiasis, reduce the number of relapses, forming a long interrecurrent period, and normalizes the state of factors of local antimicrobial protection on the surface of the mucous membranes of the lower part of the urogenital system.

Abstract Three steels were designed based on HSLA-100 with additional levels of Mn, Ni, Cr and Cu. The steels were prepared by controlled rolling and tempered at temperatures in range of 550–700°C. The continuous cooling time curves were shifted to longer times and lower temperatures with the increased tendency for the formation of martensite at lower cooling rates. The microstructures revealed that controlled rolling results in austenite with uniform fine grain structure. The steel with the highest amount of Mn showed the greatest strength after tempering at 750 °C. The top strength was attributed to the formation of Cu-rich particles. The steel with 1.03 wt.% Mn, tempered at 650 °C exhibited the best Charpy impact toughness at –85°C. On the other hand, the steel that contained 2.11 wt.% Mn and tempered at 700 °C showed the highest yield strength of 1 097.5 MPa (∼159 ksi) and an impact toughness of 41.6 J at –85°C.
