Speaker Verification is confirming the identity of an individual
from his speech. There are several possible applications for speaker
verification in security and identification systems. Some examples include
automatic teller machines and home or vehicle access. An interesting
application might even be voice imitation training.
There are several possible implementations for systems that perform speaker verification. The implementation which most commonly comes to mind is that of the matched filter. There are various characteristics of signals which can be matched. These include magnitude, energy, frequency, linear predictive coding coefficients, and cepstrum techniques.
