Objective: The primary objective of the present systematic review is to: (1) identify the current vocal tasks being used for acoustic and/or auditory perceptual analysis to differentiate between individuals with and without voice disorders. The secondary objectives are to: (2) evaluate the evidence of the sensitivity, specificity and accuracy of those vocal tasks for acoustic and/or auditory perceptual analysis in discriminating the individuals with voice disorders from those without; and (3) compare the values between the vocal tasks in discriminating individuals with voice disorders from those without., Method and Analysis: We search the following electronic databases: MEDLINE, EMBASE, CINAHL, Scopus, Web of Science Core Collection, PubMed Central and Google Scholar. Grey literature searches will include ProQuest Dissertations and Theses, ClinicalTrials.gov and the Cochrane Register of Controlled Trials. Websites of professional organisations and textbooks will be hand searched for relevant information related to the research question. Study screening, selection and data extraction will be conducted independently by two reviewers. Any disagreements will be resolved by discussion or by involving a third reviewer.The methodological quality of the included studies will be appraised using the relevant Critical Appraisal Tools by JBI. The clinical guidelines and recommendations for voice assessment by professional bodies will be appraised using the Reporting Items for practice Guidelines in HealThcare (RIGHT) checklist. The findings will be presented in the form of an information matrix with the tasks identified tabulated against the nature of the task, dimensions being tested, and their accuracy, sensitivity, and specificity in identifying individuals with voice problems., Ethics and Dissemination: Formal ethics approval is not required. The findings will be presented at national and international conferences and published in a peer-reviewed journal., Prospero Registration Number: CRD42023431634., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

Introduction: SARS-CoV-2, a highly contagious severe acute respiratory syndrome, has spread to most countries in the world and resulted in a change to practice patterns for the assessment and diagnosis of people with voice disorders. Many services are transitioning to telehealth models to maintain physical distancing measures and conserve personal protective equipment used by healthcare workers during laryngoscopy examinations. The speech-language pathology primary contact (SLPPC) assessment for patients referred to ear, nose and throat (ENT) services in Australia has been shown to reduce waiting times for assessment while streamlining access to ENT assessment and allied health practitioner treatment pathways., Methods and Analysis: A prospective observational cohort study will see patients in a newly developed telehealth model which uses the principles from a usual care SLPPC assessment protocol. Participants will be offered an initial telehealth assessment (speech-language pathology primary contact telehealth (SLPPC-T)) prior to being prioritised for a face-to-face laryngoscopy assessment to complete the diagnostic process. The telehealth assessment will collect sociodemographic information, personal and family medical history, key symptoms, onset and variability of symptoms, red-flag signs or symptoms for laryngeal malignancy, and clinical voice assessment data for auditory-perceptual and acoustic analysis. The study outcomes include (1) association of signs, symptoms and specific voice measures collected during SLPPC-T with voice disorder classification provided after laryngoscopy; (2) degree of concordance between voice disorder classification after SLPPC-T and after laryngoscopy; (3) health service and patient-related costs and health outcomes of the SLPPC-T; (4) patient and stakeholder views and beliefs about the SLPPC-T process., Ethics and Dissemination: Ethical approval has been granted prior to commencement of the study enrolment by the Gold Coast Hospital and Health Service Human Research Ethics Committee (reference number HREC/2020/QGC/62832). Results will be shared through the publication of articles in peer-reviewed medical journals and presentation at national and international scientific meetings., Trial Registration Number: ACTRN12621000427875., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022.
