Singapore, Singapore, August 16, 2008 --(PR.com
)-- Ever wondered how pranksters who make hoax calls to emergency services can be identified and brought to justice? Now there’s a technology that can identify and spot the culprit easily by analyzing voices from a regular phone system that most people make phone calls from.
A*STAR’s Institute for Infocomm Research (I2R) has invented a technology that can do just that. The Speech and Dialogue Processing team in I2R beat 45 other international institutions and topped the scores to emerge No. 1 in the National Institute of Standards and Technology (NIST) 2008 Speaker Recognition Evaluation.
NIST’s annual benchmarking provides a worldwide platform for the calibration of speech technology capabilities participated by academia and the leading institutions from the industry. The benchmarking results recognize I2R’s voiceprint technology as the state-of-the-art technology in terms of accuracy through a series of tests using real-world data. The technology is now able to detect up to 97% accuracy between two voices as to ascertain whether they are from the same speaker. This allows for the verification of voiceprints for large scale deployment in adverse acoustic environments.
Professor Lye Kin Mun, Deputy Executive Director (Research) said, “I2R has always been pitching our own capabilities in technology against other industry players through participation in global challenges. It is through this that we can learn more and improve ourselves, eventually winning international acclaim.”
The I2R team is led by Dr Haizhou Li, Department Head of Human Language Technology, with members, Bin Ma, Hanwu Sun, Donglai Zhu, Kong-Aik Lee, Khe Chai Sim, Changhuai You, Rong Tong, Ismo Kärkkäinen, Vladimir Pervouchine, Yijie Li and Susanto Rahardja.
 The National Institute of Standards and Technology (NIST), USA, develops technologies, measurement methods and standards that help US companies compete in the global marketplace. The US Congress created NIST in 1901 at the start of the industrial revolution to provide the measurement and standards needed to resolve and prevent disputes over trade and to encourage standardization.
