The RedDots Platform for Mobile Crowd-Sourcing of Speech Data

With ever increasing computational power and availability of broadband connectivity to the Internet, mobile devices have become pervasive and gaining more popularity. Capitalizing on the mobile-Internet infrastructure, a speech data collection platform was developed as part of the RedDots project which is dedicated to the study of speaker recognition over mobile devices. The RedDots platform consists of a centralized Web server receiving inputs from the crowd through mobile devices. As of the time of this writing, we have recruited speakers from 17 countries in three-month period, showing the potential of the RedDots platform to collect speech data from the worldwide population.
