Making voice biometrics more secure

Carnegie Mellon Voice Verification Technology Prevents Impersonators From Obtaining Voiceprints (India Education Diary)
Computer users have learned to preserve their privacy by safeguarding passwords, but with the rise of voice authentication systems, they also need to protect unique voice characteristics. Researchers at Carnegie Mellon University's Language Technologies Institute (LTI) say that is possible with a system they developed that converts a user's voiceprint into something akin to passwords.

The system would enable people to register or check in on a voice authentication system, without their actual voice ever leaving their smartphone. This reduces the risk that a fraudster will obtain the person's voice biometric data, which could subsequently be used to access bank, health care or other personal accounts.
