Voice Use

The purpose of this article is to describe a structured behavior modification approach tothe reduction of voice use by clients with voice disorders. The Voice Use Reduction (VUR) Program is conceptualized as part of a comprehensive approach to the treatment of voice. The VUR Program provides guidelines for the classification of voice use situations, the assignment of voice use units to different situations, and the calculation of the maximum number of units per day and per week in a severe, moderate, and low voice use reduction program. Two case examples are described to illustrate the application of the VUR Program. The results of an evaluation of the VUR Program by 10 female students who presented with vocal nodules and applied the program also are included.

Study Participants

Objective: Because there are few population-based studies regarding the epidemiology of benign voice diseases, the present study used a nationwide population-based claims database (the National Health Insurance Research Database) to investigate the epidemiology of benign voice diseases among the general adult population in Taiwan. Methods: Study participants were retrieved for those patients who were 20 to 90 years old with a diagnosis of benign voice diseases that were defined by International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes from 2006 to 2014. Patient visits were grouped into infectious (ICD-9-CM: 012.3, 032.3, 034.0, 090.5, 095.8,101, 464.0, 464.20, 464.21, 465.x, 476.0, 476.1) and noninfectious (ICD-9-CM: 306.1, 478.3x, 478.4, 478.5, 748.3, 784.4x) dysphonia groups. Results: Benign voice disorders have a prevalence of approximately 3.6% in Taiwan as of 2014. The year-to-year prevalence decreased gradually in the query period. Infectious dysphonia diagnoses were higher than noninfectious ones. Dysphonia caused by noninfectious diagnoses was most prevalent in the 60 to 79 years age group. Dysphonia caused by infectious diagnoses was highest in 20 to 39 years group. Noninfectious dysphonia diagnoses were more common in women. Conclusion: The prevalence of voice disorders among the adult population in Taiwan was 3.6% in 2014. Voice disorders are more common in women and occur primarily in the 20 to 39 years age group. Infectious dysphonia is more common than noninfectious dysphonia. The results may be underestimated due to limitation of the database. This is the first population-based epidemiology study of adult voice disorders.

Introduction. Contemporary occupational diseases are increasingly expressed by function disorders, which include voice disorders, forcing workers to request a leave of absence from work and leading to an incapacity to perform their work activities. Teachers have the higher prevalence of vocal disorders among the professionals who use their voices professionally, which is reported as the second cause of teaching work absences in Brazil. Objective. To analyze the environment and organization aspects of the teaching work associated with the development of voice disorder of teachers, according to the International Classification of Functioning, Disability and Health (ICF). Method. This study consisted of two steps. Initially, an integrative bibliographic review was performed to search for references related to the topic in the LILACS, MEDLINE and SCIELO databases, using the health descriptors "voice disorders" and "teachers". Then, the selected articles were read in full in order to identify the work factors associated with the voice disorder and compared with the theoretical framework of the ICF, in order to identify possible indicators of loss of functioning and capacity for teaching work resulting from voice disorders. Results. The presence of dust and noise were the most prevalent environment aspects. In turn, the high demand for work and the lack of autonomy to perform the work were identified as factors related to the organization of the work of the teaching work, as well as stress at work and the presence of situations of violence at school as the most reported work absences. Conclusion. As shown, the factors of teaching work described impact all components of functioning and lead to the incapacity of the teacher to work. The use of the ICF may contribute to systematize and quantify, in a standardized way, the loss of functioning and work capacity resulting from voice disorders, in addition to assisting in the development of public health promotion policies and in the prevention of vocal disorders in teachers.

Abstract Several tools have been introduced to achieve early detection of voice disorders. Among these tools are the human factor cepstral coefficients HFCC combined with prosodic parameters, the noise-harmonic ratio (NHR), the harmonic-noise ratio (HNR), analysis of trend fluctuations (DFA) and fundamental frequency (F0). These parameters are introduced and calculated in every frame. In this work, we used a variation of HFCC called equivalent rectangular bandwidth (ERB) to study the effects of HFCC on the classification of pathological voices. Using the HTK classifiers, the classification is carried out on two pathological databases, Massachusetts Eye and Ear Infirmary (MEEI) and Saarbruecken Voice Database (SVD). To assess the performance of the system, we used sensitivity and specificity.
