In this paper, we propose a novel speaker verification method which determines whether a claimer is accepted or rejected by the rank of the claimer in a large number of speaker models instead of score normalization, such as T-norm and Z-norm. The method has advantages over the standard T-norm in speaker verification accuracy. However, it needs much computation time as well as T-norm that needs ...

We construct an elliptic curve over Q(i) with torsion group Z/4Z× Z/4Z and rank equal to 7 and a family of elliptic curves with the same torsion group and rank ≥ 2.

We introduce the notion of locally finite decomposition rank, a structural property shared by many stably finite nuclear C∗-algebras. The concept is particularly relevant for Elliott’s program to classify nuclear C∗algebras by K-theory data. We study some of its properties and show that a simple unital C∗-algebra, which has locally finite decomposition rank, real rank zero and which absorbs the...

TELEPHO E-BASED TEXT-DEPE DE T SPEAKER VERIFICATIO In this thesis, we investigate model selection and channel variability issues on telephone-based text-dependent speaker verification applications. Due to the lack of an appropriate database for the task, we collected two multi-channel speaker recognition databases which are referred to as text-dependent variable text (TDVT-D) and textdependent ...

We show that many algebraic actions of higher-rank abelian groups on zero-dimensional groups are mutually disjoint. The proofs exploit differences in the entropy geometry arising from subdynamics and a form of Abramov–Rokhlin formula for half-space entropies. We discuss some mutual disjointness properties of algebraic actions of higher-rank abelian groups on zero-dimensional groups. The tools u...

We prove that generous non-nilpotent Borel subgroups of connected minimal simple groups of finite Morley rank are self-normalizing. We use this to introduce a uniform approach to the analysis of connected minimal simple groups of finite Morley rank through a case division incorporating four mutually exclusive classes of groups. We use these to analyze Carter subgroups and Weyl groups in connect...

In this paper we propose a new speaker identi cation system, where the likelihood normalization technique, widely used for speaker veri cation, is introduced. In the new system, which is based on Gaussian Mixture Models, every frame of the test utterance is inputed to all the reference models in parallel. In this procedure, for each frame, likelihoods from all the models are available, hence th...

The seven citation tones of the Southern Min dialect of Zhangzhou are described impressionistically, and a linguistic-tonetic representation of their acoustics derived from the z-score normalization of the tones of 9 male and 12 female speakers. A normalization of the raw mean tonal data is shown to be slightly superior to a log10 transform, delivering about an eight-fold reduction in the betwe...

We establish structural controllability results for matrix pairs [A, B] where .4=A0+Z piAi, B=B,+Z piB', with tho At, Bi fixed, and the pr free scalar parameters. Tho results characterize structural controllability in several wsys, via, tests involving the cllecking of the rank or the evaluation of the determinant of various constant matrices formed from t,he At, Bi. A number of the result,^ us...
