MTI currently has Nuance SpeechSecure speaker verification software. However, we currently have no clients using the package, so we can’t attest to its performance. SpeechSecure uses biometric technology to verify a caller’s identity based on the characteristics of his or her unique vocal patterns. SpeechSecure provides a convenient and extremely tight level of security for callers who access personal information over the telephone. From financial services to telephony services, SpeechSecure opens the door to a host of commercial applications where high security and/or high convenience is required.
