Resumo
Authentication and security in automated systems have become very much necessary
in our days and many techniques have been proposed towards this end. One of these
alternatives is biometrics in which human body characteristics are used to authenticate the
system user. The objective of this work is to present a method of text independent speaker
identi cation through the replication of pitch characteristics. Pitch is an important speech
feature and is used in a variety of applications, including voice biometrics. The proposed
method of speaker identi cation is based on short records segments of speech, namely,
three seconds for training and three seconds for the speaker determination. From these
segments pitch characteristics are extracted and are used in the proposed method of
replication for identi cation of the speaker, resulting in a reduction in the Equal error
rate (EER) values.
