This paper describes a rapid model adaptation technique for spontaneous speech recognition. The proposed technique utilizes a multiple-regression hidden Markov model (MRHMM) and is based on a style estimation technique of speech. In the MRHMM, the mean vector of probability density function (pdf) is given by a function of a low-dimensional vector, called style vector, which corresponds to the i...

This paper introduces the performance evaluation of statistical approaches for Text-Independent speaker recognition system using source feature. Linear prediction (LP) residual is used as a representation of excitation information in speech. The speaker-specific information in the excitation of voiced speech is captured using statistical approaches such as Gaussian Mixture Models (GMMs) and Hid...

The Peukert relationship was originally introduced in 1897 for lead-acid batteries and defines one of the most common parameters for battery performance evaluation. This article assesses its application for lithium-ion batteries. From the performed analysis, we can conclude that the Peukert relationship is suitable in a narrow working range such as limited current range and almost constant work...

− In this paper, we present the results of evaluating the performance of the forward link of a CDMA cellular radio system. We use a semianalytical approach consisting of the waveform level simulation of the analog channel followed by the hidden Markov modeling of the discrete channel. The performance parameters of the discrete channel were evaluated analytically using the hidden Markov model an...

In the context of liberalized markets, market outcomes generally result from the strategic interactions of all market players. Generation company (Genco), as the distributed players, build their subjective demand evaluations (SDFs) about market for optimal bidding purpose. Due to the differences in terms of data availability and modeling techniques, subjective demand models held by various Genc...
