is our voice really *unique??
Recently there are a lot of emails from my bank suggesting me to click to
upgrade my phone banking security by providing them my voice, then
the next time my voice can be used to access my phone banking service
more quickly. The emails are really from my bank.
I'd like to know if our voice is really unique and can act as fingerprint?
Can't two people in the world have the same voice? What is the parameter
of our voice that makes us unique? Frequency ? Or is it only an "improved" security to avoid fraud only, instead of bullet proof
