Voice production is studied and applied in many disciplines such as medicine, speech-language pathology, music, physics, psychology, phonetics, art, and biology.
It was the result of a mixed initiative of physicians, speech-language pathologists and singing teachers that belonged to the former association ‘Sociedade Brasileira de Laringologia e Voz – SBLV’ (Brazilian Society of Laryngology and Voice), under the presidency of Dr. Nedio Steffen.
In the United States, the American Academy of Otolaryngology – Head and Neck Surgery officially recognized this celebration in 2002 and in that year the event obtained the name ‘World Voice Day’.
Presently the group consists of 66 members who initiate and help coordinate events for World Voice Day in their respective countries.
In 2018 almost 600 events in 50 countries took place, and all are listed on the web site world-voice-day.org where further information can be found.
