Pittsford, New York-based Moscom Corp has introduced its VoiceLock system which uses patented voice recognition technology to reinforce the security of PABXs providing remote access to long distance facilities: the VoiceLock system uses speaker-dependent voice recognition technology to validate spoken passwords and ensure that only authorised personnel gain access to outside lines; a user attempting to access the PABX will be remotely asked by the system to enter an authorisation code and state a special password, and the system then compares the caller’s voice with a voice print on file; speaker validation takes seconds and recognition tolerances can be adjusted for varying security requirements; VoiceLock is used with ordinary telephones and standard PABXs, and has an entry price of $29,500.
