Join our Global Perceptual Voice Evaluation Marathon!

Hosted on All-Voiced (all-voiced.com), this global online event returns for its second edition, inviting participants worldwide to take part in auditory-perceptual voice evaluation throughout World Voice Day.

Participants will not only contribute to research, but also actively train their listening skills through real-time feedback, allowing them to compare their perceptual judgments with aggregated evaluations from expert raters.

All assessments collected will contribute to the Global Database of Auditory-Perceptual Voice Assessments, supporting research on how voice qualities are perceived across different cultures, contexts, and levels of expertise.

A real-time counter will track global participation, and a dynamic map will highlight where evaluations are being submitted.

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.

Learn. Compare. Contribute.

Let’s make World Voice Day truly international.
