World Voice Day (WVD) is a worldwide annual event that takes place on April 16 devoted to the celebration of the phenomenon of voice.[1] The aim is to demonstrate the enormous importance of the voice in our daily lives, as a tool of communication, and as an application of a large number of sciences, such as physics, psychology, phonetics, art, and biology. It was initiated in 1999 as a combined effort of American and European otolaryngologists and speech and language pathologists, particularly the American Academy of Otolaryngology – Head and Neck Surgery (AAO-HNS) and MD Mario André in Portugal. Now, the celebration of the World Voice Day is scattered around the globe, including concerts, symposia, open house at voice clinics and voice education institutes, TV shows, and radio programs.
