“…The study did not perform perceptual analysis specifically on the impact of MTD on pitch target and pitch movement in NV tone because the main purpose of the study was to provide supplementary data to interpret findings in a previous study. 12 The perceptual aspects of the findings in this study could be viewed partially in that study 12 in which we documented the perception of tones (eg, T5) with extensive F0 variation and with pitch target affected by MTD. Nevertheless, listeners' responses to changes in pitch targets and movement size in tone phonation should be clarified.…”

“…This problem is important in NV tones recognized mainly using F0 contour such as T4 and T5. Our previous study 12 found that listeners had difficulties identifying a number of samples of these two tones. In particular, some T4 samples were perceived as T2 (falling tone) and some T5 samples as T4 (curved tone).…”

“…Antagonistic effects of this muscle may occur only when tonal F0 is elevated to the high range but not at low or moderate pitch ranges, which may explain why there is no difference between MTD and normal speakers in F0 of low tones. 12 However, in MTD, this muscle may not be the only external laryngeal muscle to be hyperfunctional. In patients with MTD, Angsuwarangsee and Morrison 27 also found increased tension in the thyrohyoid muscle-an antagonist of the cricothyroid muscle.…”

“…Variations in certain acoustic parameters have been described in comparison to patients with MTD and healthy subjects or patients with other pathology. An increase in the fundamental frequency, f0, attributed to an increase in the tension and subglottal pressure, and a reduction in high frequencies, attributed to the lack of relaxation in the laryngeal muscles [36], have been described. In addition, variations have been reported in other acoustic parameters, such as shimmer, jitter, NHR (noise to harmonic; Table 2 is a summary of articles about the diagnosis ratio), and other noise-related parameters.…”

Background: Muscle Tension Dysphonia is a relatively new clinical entity that, despite being one of the most frequent causes of functional dysphonia, is little-known by many otorhinolaryngologists. Objective: The objective of the current work is to describe the evolution of Muscle Tension Dysphonia—the concepts and the ways it has been diagnosed and treated—from its first descriptions to our current knowledge. Design: A scoping review was conducted using the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) checklist. A search of three bibliographic databases was performed to identify original articles on Muscle Tension Dysphonia. Study selection and characterization was conducted by three independent reviewers and was further reviewed by a fourth individual. In case of relocating any of the studies, it was performed by agreement of two reviewers. We excluded articles not written in English or Spanish, letters to the editor, review articles, studies of the pediatric population, articles related to dysphagia, and other publications that were not relevant. Results: The search identified 1144 articles published from 1983 to December 2022. A total of 581 studies were repeated and another 462 were excluded because they were not written in English or Spanish, were not original articles, or were not relevant to the objective of the study. Finally, 101 articles were included in the review. The articles included in the review were divided into three groups considering the objective and conclusions of each study: 21 articles were classified as “Etiology and Physiopathology”, 29 articles as “Diagnosis”, and 51 articles were included in the “Treatment” group. Conclusions: The concept of Muscle Tension Dysphonia has been developed during the last forty years. For its diagnosis, endoscopic visualization of the larynx is crucial, but must be combined with the patient’s clinical history and other methods can also be useful. This entity should be addressed in a multidisciplinary approach, with the active participation of speech therapists. Most therapeutic options include voice education, vocal hygiene, and rehabilitation of the voice.

“…In the current study the focus is on the effect of a voice disorder on lexical tone variation. Voice disorders could potentially interfere with tone variation due to compromised vocal fold movement and configuration of the glottis (Nguyen & Kenny, 2009). The inability to vary voice pitch adequately may impact the ability of an individual to control lexical tone and therefore to convey an intelligible message.…”

Purpose. The aim was to determine if the presence of a voice disorder in speakers of Setswana, an African tone language, will negatively impact the accuracy of identification by typical first language judges of words belonging to tonal minimal pairs. Method. A quasi-experimental between-group comparison and individual case studies were conducted. Five participants with different types and degrees of voice disorders and nine control participants produced 10 tonal minimal word pairs. Five judges had to identify which of a pair was produced.Result. The mean scores of the control and experimental speakers as groups differed, but the difference was not statistically significant. Control participants scored between 19.6/20 and 14.2/20 words correctly identified. Individual data revealed that four of the nine control participants attained at least one perfect score across judges and six had mean scores of 18.0/20 and higher. The highest scoring experimental participant, presenting with a mild voice disorder, attained a mean of 18.0/20. The lowest scoring participant, presenting with the most severe dysphonia, had a mean of 12.2/20 words correctly identified. Conclusion.These preliminary results appear to suggest that a severe voice disorder could compromise lexical tone variation and by implication the intelligibility of a message.
