Voice Biometrics Based on Pitch Replication

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 article is to present a method of text independent speaker identification 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 identification is based on short 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 identification of the speaker
