voice waves

The ability to communicate through speech is an essential life skill and a vital part of what distinguishes us as humans. We use our voices to articulate our thoughts, express our feelings and relay our needs. Without access to proper care and treatment, voice disorders can have a debilitating and severe impact upon quality of life.

About the program

The Dr Liang Voice Program will support research, research training, clinical training and education in the field of laryngeal and voice conditions. The objective of this world first program is to transform quality of care and improve outcomes for those affected by voice disorders.

The newly created voice program at the University of Sydney will establish the reputation of the University as a leading centre of excellence for research into laryngeal disorders in the Asia–Pacific region.

Our approach

Leveraging expertise in speech pathology and ear, nose and throat (ENT) surgery, the Dr Liang Voice Program aims to improve the future diagnosis, treatment, and recovery of patients with laryngeal conditions.

It will unite the disciplines of speech pathology and ENT surgery and build on existing tools and emerging technologies to educate laryngeal clinicians. Establishing a fellowship program to increase access to talented surgical and speech pathology clinicians trained in this model of care is a key objective.

The establishment of the Dr Liang Voice Program within the University’s new multidisciplinary Health Precinct will foster important academic collaboration with adjacent hospitals, clinical schools, clinical research facilities, surgical training facilities, cancer specialists, public health experts, and allied health professionals.

The Dr Liang Voice Program aims to reduce significantly the potential debilitating effects of voice disorders through a coordinated model of surgical and voice rehabilitation treatments. It will have a direct and life-changing impact for people with voice conditions.

Clinical program leadership

Drawing on existing expertise at the University of Sydney in the field of laryngology and voice rehabilitation, the Program will be led by two internationally respected Sydney-based voice clinicians.

Cate Madill

Dr Cate Madill is Director of the Voice Research Laboratory at the Faculty of Health Sciences and conducts clinical research into the mechanism and processes that change the voice. This includes the identification of optimal vocal function to improve effectiveness of treatment and training programs, and research into optimal voice outcomes after laser resection of early glottic cancer. She conducts experimental and applied clinical research into the mechanism and processes that change the voice. Dr Madill's research involves use of the latest voice measurement equipment including high-speed larygoscopy, ultrasound, respiratory, electrophysiology and acoustic measurement and psychoacoustic evaluation.

Daniel Novakovic


Dr Daniel Novakovic is a senior clinical lecturer at the Northern Clinical School. He is an ear nose and throat surgeon with specialised fellowship training in laryngology and head and neck surgery. Dr Novakovic is one of a few surgeons in Australia to have undergone formal fellowship training in the field of laryngology and specifically neurolaryngology. He graduated from the University of Sydney Medical School in 2000 and completed Otolaryngology Training in Australia to attain Fellowship to the Royal Australasian College of Surgeons (FRACS) in 2007.

As clinicians, Dr Madill and Dr Novakovic work in consultation to provide a coordinated approach to care. Their patients receive both surgical and speech pathology consultations pre- and post-surgery, followed by an ongoing speech pathology treatment program to optimise results.
