Text-Independent Speaker Verification
INTRODUCTION
Among the most popular measurements for biometric identification are fingerprint, face, and voice.the speaker
recognition area has a long and rich scientific basis with over
30 years of research, development, and evaluations.

a speaker verification system:

step 1:
It consists in extracting parameters
from the speech signal to obtain a representation
suitable for statistical modeling as such models are extensively
used in most state-of-the-art speaker verification systems.

Step2:
obtaining a statistical model from the parameters.

SPEECH PARAMETERIZATION:
It involves transforming the speech signal to a set of feature vectors. Most of such systems relies on a cepstral representation of
speech.
