Towards the use of sub-band processing in automatic speaker recognition
Automatic speaker recognition uses a person’s voice as a means of identifying them. It has many practical applications, particularly in the area of security systems. The thesis investigates the application of neural networks (both classifying and predicting) to the problem, as well as offering a …

Analysis of nonmodal glottal event patterns with application to automatic speaker recognition
… are likely to contain information about speaker identity, language, dialect, and vocal-fold health. As a basis for testing such dependencies, we develop a representation of patterns in the relative timing and height of nonmodal glottal pulses. To extract the timing and height of candidate …

Automatic assessment of voice similarity and its implications for forensic applications
Speakers of varying degrees of similarity are required for forensic purposes, for instance officer or witness protection, relevant populations for forensic speaker recognition, or voice parades and earwitness assessments. In the past decade, the collection of speech has become much easier, offering …

ΝΕΑ ΜΕΘΟΔΟΣ ΑΥΤΟΜΑΤΗΣ ΑΝΑΓΝΩΡΙΣΗΣ ΟΜΙΛΗΤΗ
THE THESIS PRESENTS A NEW METHOD FOR AN AUTOMATIC SPEAKER RECOGNITION SYSTEM, WHICH COULD BE FAVORABLY IMPLEMENTED FOR IDENTIFICATION AS WELL AS FOR VERIFICATION PURPOSES. THIS METHOD IS BASED ON A SUBSTANTIALLY REDUCED NUMBER OF ELEMENTS OF THE PATTERN VECTOR IN COMPARISON TO SIMILAR METHODS. THE …

Robust speaker recognition in reverberant condition : toward greater biometric security
Automatic speaker recognition systems have developed into an increasingly relevant technology for security applications in modern times. The primary challenge for automatic speaker recognition is to deal with the variability of the environments and channels from where the speech was obtained. In …

An approach to a robust speaker recognition system
This dissertation presents a design of a robust, automatic speaker recognition (ASR) system. The ASR system is designed to work with both text-independent and text-dependent speaker recognition. Several speaker spectral features are studied to determine their contribution in term of accuracy to the …
