Conference Proceeding: Arabic Speech Recognition System Based on CMUSphinx
[show abstract] [hide abstract]
ABSTRACT: In this paper we present the creation of an Arabic version of Automated Speech Recognition System (ASR). This system is based on the open source Sphinx-4, from the Carnegie Mellon University. Which is a speech recognition system based on discrete hidden Markov models (HMMs). We investigate the changes that must be made to the model to adapt Arabic voice recognition.Computational Intelligence and Intelligent Informatics, 2007. ISCIII '07.

Article: Bound Polaron in CuCl and GaAs Quantum Dots
[show abstract] [hide abstract]
ABSTRACT: We calculated the binding energy of a polaron bound to a hydrogenic donor impurity located in a spherical quantum dot by means of a variational and numerical technique for finite potential models. The polaronic effect has been considered taking into account the ion-phonon coupling under the Lee Low Pines approach. The results show that the binding energies are drastically affected by the dot radius, the potential barrier height and the polaronic effects. Comment: 6 pages, 5 figures04/2007;
