Background: Speech-language and hearing (SLH) professions in South Africa are facing significant challenges in the provision of clinical services to patients with communication disorders from a context that is culturally and linguistically diverse because of historic exclusions of black and African language speaking candidates in higher education training programmes. Over 20 years post the democratic dispensation, minimal changes have been noted in terms of the training, research as well as clinical service provision in these professions, although the demographic profile of students is seen to be transforming gradually. Objectives: We offer this viewpoint publication as a challenge to the professions to interrogate their academic and clinical orientation in respect of African contextual relevance and responsiveness. Method: We do this by identifying gaps within the higher education context, highlighting the influencing factors to the provision of linguistically and culturally appropriate SLH training and clinical services in South Africa, while asking questions about what SLH students and practitioners need to carefully consider. Results: We make recommendations about what needs to happen within the SLH professions in South Africa in order to stay safe from the dangers of a single story. Conclusion: We invite debate in order to allow for constructive engagement with this complex issue within the South African SLH professions.

Background: The current study aimed to determine the accuracy of UHear™, a downloadable audiometer on to an iPod Touch©, when compared with conventional audiometry.Methods: Participants were enrolled primary school scholars. A total number of eighty-six participants (172 ears) were included. Of these eighty-six participants, forty-four were female and forty-two were male; with the age ranging from 8 years to 10 years (mean age, 9.0 years). Each participant underwent two audiological screening evaluations; one by means of conventional audiometry and the other by means of UHear™. Otoscopy and tympanometry was performed on each participant to determine status of their outer and middle ear before each participant undergoing pure tone air conduction screening by means of conventional audiometer and UHear™. The lowest audible hearing thresholds from each participant were obtained at conventional frequencies.Results: Using the Paired t-test, it was determined that there was a significant statistical difference between hearing screening thresholds obtained from conventional audiometry and UHear™. The screening thresholds obtained from UHear™ were significantly elevated (worse) in comparison to conventional audiometry. The difference in thresholds may be attributed to differences in transducers used, ambient noise levels and lack of calibration of UHear™.Conclusion: The UHear™ is not as accurate as conventional audiometry in determining hearing thresholds during screening of school-aged children. Caution needs to be exercised when using such measures and research evidence needs to be established before they can be endorsed and used with the general public.

Background: The emergence of the coronavirus disease 2019 (COVID-19) pandemic has resulted in communication being heightened as one of the critical aspects in the implementation of interventions. Delays in the relaying of vital information by policymakers have the potential to be detrimental, especially for the hearing impaired.Objectives: This study aims to conduct a scoping review on the application of artificial intelligence (AI) for real-time speech-to-text to sign language translation and consequently propose an AI-based real-time translation solution for South African languages from speech-to-text to sign language.Methods: Electronic bibliographic databases including ScienceDirect, PubMed, Scopus, MEDLINE and ProQuest were searched to identify peer-reviewed publications published in English between 2019 and 2021 that provided evidence on AI-based real-time speech-to-text to sign language translation as a solution for the hearing impaired. This review was done as a precursor to the proposed real-time South African translator.Results: The review revealed a dearth of evidence on the adoption and/or maximisation of AI and machine learning (ML) as possible solutions for the hearing impaired. There is a clear lag in clinical utilisation and investigation of these technological advances, particularly in the African continent.Conclusion: Assistive technology that caters specifically for the South African community is essential to ensuring a two-way communication between individuals who can hear clearly and individuals with hearing impairments, thus the proposed solution presented in this article.

Background: Universal Newborn Hearing Screening (UNHC) is the gold standard toward early hearing detection and intervention, hence the importance of its deliberation within the South African context.Aim: To determine the feasibility of screening in low-risk neonates, using Otoacoustic Emissions (OAEs), within the Midwife Obstetric Unit (MOU) three-day assessment clinic at a Community Health Centre (CHC), at various test times following birth.Method: Within a quantitative, prospective design, 272 neonates were included. Case history interviews, otoscopic examinations and Distortion Product OAEs (DPOAEs) screening were conducted at two sessions (within six hours and approximately three days after birth). Data were analysed via descriptive statistics.Results: Based on current staffing profile and practice, efficient and comprehensive screening is not successful within hours of birth, but is more so at the MOU three-day assessment clinic. Significantly higher numbers of infants were screened at session 2, with significantly less false-positive results. At session 1, only 38.1% of the neonates were screened, as opposed to more than 100% at session 2. Session 1 yielded an 82.1% rate of false positive findings, a rate that not only has important implications for the emotional well-being of the parents; but also for resource-stricken environments where expenditure has to be accounted for carefully.Conclusion: Current findings highlight the importance of studying methodologies to ensure effective reach for hearing screening within the South African context. These findings argue for UNHS initiatives to include the MOU three-day assessment to ensure that a higher number of neonates are reached and confounding variables such as vernix have been eliminated.
