Re: FFS When will people learn?
Not true. It depends on the ratio of the intra to inter-variance of the parameter being measured. Finger-prints are unique, but the parameters that measure them are finite. If you can measure accurately a fingerprint, it can be better than a password of some aribitrary complexity. If your fingerprint parameters can only differentiate 10 different prints then you have a problem.
The issue with speech is the parameters have a lot of intra-variance such that when you speak you map onto other peoples patterns. Its not necessarily that your voice matches, its the parameters that represent the voice that overlap.
