South African researchers have developed and tested a low-cost, smartphone-compatible medical device designed to significantly improve access to voice disorder screening across the country.
The researchers at the University of Pretoriaon said “the portable system enables healthcare practitioners to capture high-resolution images and video of vocal cords using mobile technology.”
The development offers a more accessible alternative to conventional diagnostic procedures such as laryngoscopy, which typically require specialised equipment and trained personnel.
The innovation is part of ongoing research within the university’s Department of Speech-Language Pathology and Audiology, focused on addressing gaps in early detection.
Experts note that voice disorders often go undiagnosed until symptoms become severe, particularly in regions with limited access to specialist care.
According to lead researchers, the device has been designed to reduce cost and logistical barriers, making it suitable for use in a wider range of healthcare settings, including primary care and remote communities.
By enabling earlier identification of vocal conditions, the technology could help accelerate treatment and improve long-term health outcomes.
According to the source, the new approach reflects a broader shift towards scalable, affordable medical technologies aimed at strengthening healthcare systems and expanding diagnostic capabilities in underserved areas.
Researchers emphasise that integrating mobile-based solutions into routine care could play a key role in improving early intervention and reducing pressure on specialised medical services.
