TL;DR: A framework has been created to give a way to quantitative vocal stacking appraisal for the avoidance of voice issues and the advancements in signal processing have helped to achieve this goal.
Abstract: Great vocal well-being is a key worry to proficient voice clients such ad instructors and artists. Consequently, to improve the utilization of voice and appropriate recovery to reestablish vocal well-being is the need of the day. A framework has been created to give a way to quantitative vocal stacking appraisal for the avoidance of voice issues. The advancements in signal processing have helped us to achieve this goal. Time dose, cycle dose, energy dose, and distance dose are the vital voice dosage measures citied in writing. The initial two measurements are ascertained in the study. The parameters which determine these measurements are voicing time, fundamental frequency of speech, and intensity of speech. Silence/unvoiced/voiced classification of speech signal has been done. The fundamental frequency has been extracted by cepstrum analysis. Voice doses are calculated using the above parameters, and tests are done on male and female audio samples. In this study, MATLAB platform is used for speech signal recording as well as analysis.

TL;DR: There is an urgent need for research to support occupational voice health and safety risk measurement, prevention and intervention and large population-based studies are required with a focus on the health and economic burden of occupational voice disorders.
Abstract: Purpose of review The current article reviews recent literature examining occupational voice use and occupational voice disorders (January 2018-July 2019). Recent findings Our understanding of the prevalence of voice disorders and work-related vocal use, vocal load and vocal ergonomics (environmental and person influences) across different occupations is continuing to build. There is encouraging evidence for the value of intervention programs for occupational voice users, particularly of late with performers, teachers and telemarketers. Education and prevention programs are emerging for other 'at risk' occupations. Summary Occupational health and workforce legislation does not adequately acknowledge and guide educational, preventive and intervention approaches to occupational voice disorders. Voice disorders are prevalent in certain occupations and there is an urgent need for research to support occupational voice health and safety risk measurement, prevention and intervention. Large population-based studies are required with a focus on the health and economic burden of occupational voice disorders.

01 Sep 2005TL;DR: An integrated interface called CATSEAR is under development for database collection, data analysis, therapy design, and patient monitoring for speech pathologists and for patients with speech/language disorders and voice quality problems.
Abstract: This study focuses on the development of software tools integrated with speech processing technology for speech pathologists and for patients with speech/language disorders and voice quality problems. An integrated interface called CATSEAR is under development for database collection, data analysis, therapy design, and patient monitoring. Automatic assessment techniques using pattern recognition algorithms enable the speech pathologist to employ objective criteria during speech therapy as well as guide the patients when the pathologist is not available. The performance of the patient can be monitored over time. CATSEAR enables sharing of databases among speech therapists with remote collaboration and pre-recorded analysis facilities. It can also be used for relatively mild disorders like mispronunciation and for singing voice training.
