Landmarks across Australia and New Zealand will be bathed in red light for World Voice Day 2024, in a campaign led by the Australian Dysphonia Network (ADN).

The initiative aims to 'Resonate. Educate & Celebrate' the human voice, sparking conversations about voice health, voice loss, and voice changes.

Chronic dysphonia, a condition that affects the voice, can develop due to damage to the larynx, underlying health conditions, overuse or poor vocal technique, or as a standalone neurological disorder like Spasmodic Dysphonia. It's estimated one in every 100,000 people in Australia and New Zealand are affected by Spasmodic Dysphonia including Australian singer, Jenny Morris, as well as overseas celebrities such as Scott Adams and Robert F Kennedy Junior.

Approximately 30% of occupations are voice-dependent, making dysphonia a life-changing condition for many. The Australian Dysphonia Network was established in 2016 to support people impacted by a voice disorder.

World Voice Day was founded in Brazil in 1999 to draw attention to the science and phenomenon of voice production. It is now celebrated in over 50 countries globally. The 2024 campaign aims to raise awareness and educate the public about the importance of voice health and the impact of voice disorders.

The NFP said the illumination of landmarks in red symbolises the resonance of the human voice and serves as a beacon to start conversations about voice health. It's a call to action for everyone to understand the importance of voice health, the potential impact of voice disorders, and the need for further research and support in this area.
