TOEFL programme unveils state-of-the-art Biometric Voice Identification Software to Increase test security globally.

 

 

Princeton (US). ETS, the creator of the TOEFL (Test of English as a Foreign Language) test, announced the introduction of biometric voice identification to maintain fair and reliable TOEFL testing.

Similar to the highly advanced speaker identification platforms used by government and law enforcement agencies, the software uses statistical pattern matching techniques, advanced voice classification methods, and inputs from multiple systems to compare speech samples from TOEFL test takers. Launched earlier this month, the speaker identification system offers the ability to create voice prints for detailed analysis to validate TOEFL test takers.

The new technology will be used as part of test security investigations in 2012 and beginning in 2013 will gradually be used on a larger scale.  David Hunt, Vice President and Chief Operating Officer of ETS's Global Division explains the need, "Including a state-of-the art speaker identification component to the TOEFL's security system further strengthens our ability to detect attempts to gain an unfair advantage, a common concern in academia today."
