| Abstract | OBJECTIVE
Routine clinical voice evaluation includes assessment procedures such as case history, acoustic, auditory-perceptual, laryngeal visualization, aerodynamic, and patient-reported outcome measures. While studies have been carried out to suggest several vocal tasks for acoustic and auditory perceptual analysis of voice, we do not have a thorough understanding of vocal tasks in their ability to clinically differentiate between them. Thus the present systematic review is being conducted to identify the vocal tasks being used and evaluate their sensitivity and specificity in discriminating between individuals with and without voice problems.
METHODOLOGY
A systematic literature search was conducted on electronic databases, textbooks, and websites of relevant professional organizations for studies. The gathered literature was imported on Covidence for screening. After the removal of duplicates, title and abstract screening was conducted followed by full-text screening. A customized data extraction template was created for the purpose of data extraction and methodological quality was appraised using relevant tools.
RESULTS
A total of 4994 studies were screened through two stages i.e. title and abstract followed by full-text screening to identify over 200 relevant studies. Data extraction and methodological quality appraisal are ongoing. Preliminary findings are suggestive of a common generic use of voice tasks for acoustic and auditory perceptual analysis. Further, specific tasks are being tested for their sensitivity towards specific voice conditions.
CONCLUSION
The systematic review aims to identify the varied tasks being used for the acoustic and auditory perceptual analysis of voice and determine their sensitivity and specificity in discriminating between individuals with and without voice problems. These findings will enable a better selection of vocal tasks for clinical and research purposes.
