The link in the sentence "Each human being has a voice that is distinct and different from everyone else?s" is to https://theconversation.com/is-every-human-voice-and-fingerprint-really-unique-63739?sr=1 which is actually titled "Is every human voice and fingerprint really unique?" *That* piece leads with "Barclays, the UK bank, is to replace the password system on its phone banking service with personal voice recognition. 'Unlike a password, each person?s voice is as unique as a fingerprint,' said Steven Cooper, Barclays? head of personal banking. Yet the reality is we have no idea whether either fingerprints or voices are unique at all." and closes with "Dangers and misunderstandings occur when too much is claimed for such techniques. They are of limited usefulness. They should not be relied upon totally ? as overriding evidence or for security systems on their own. They must be relied upon only as part of a wider case or system of checks." Bit of a difference there, you agree? > Any biometric system can be spoofed.
