ETS rolls out voice biometric security for English-language tests

May 8, 2014 - 

ETS has announced that it has now integrated voice biometric identification to its TOEFL Program for English-language tests.  Voice biometrics is being used as a part of the screening process for all TOEFL test takers, in an attempt to identify suspected impersonators.

“The pilot phase of the biometric voice identification software proved it to be a major asset in identifying suspected impersonations and enabling ETS to cancel those scores before they were reported,” David Hunt, Senior Vice President, Global Education and Workforce Division at ETS said. “Security is a top priority at ETS, and we are proud to have this best-in-class security measure in place for our TOEFL test. Valid scores depend on secure administrations, and this powerful new tool will help to ensure just that.”

According to the company, it started a pilot of the software in 2012 and the system has now been rolled out globally for test takers. ETS currently has a patent pending on the use of voice biometric identification software for this purpose, and the company says the TOEFL test is the only English-proficiency test using voice biometrics.

ETS says it plans to extend the use of voice biometrics to another test in its portfolio this year.

According to research published last year, the face and voice biometrics market is set to reach $3 billion by the end of 2018.
