Join our Global Perceptual Voice Assessment Marathon!

Hosted on All-Voiced (all-voiced.com), this online event invites participants worldwide to contribute auditory-perceptual voice evaluations throughout World Voice Day. All assessments collected will be used for research as part of the Global Database of Auditory-Perceptual Voice Assessments project, helping to advance our understanding of voice qualities across different cultures.

A real-time counter will track contributions, and a dynamic map will highlight where assessments are being submitted most actively. To ensure accessibility across all time zones, the event will run from 00:00 in the first place where April 16 begins (UTC+14) until 23:59 in the last place where April 16 ends (UTC-12), spanning a total of 50 hours globally.

Let’s make World Voice Day truly international!
