Recognition results for Croatian and Slovenian speech are presented, as well as bilingual speech recognition results when using common acoustic models. We propose two different approaches to the language identification problem and show recognition results for the two acoustically similar languages like Slovenian and Croatian.

The proposed coder employs a recently introduced adaptive fuzzy prediction methodology in the predictor design. In addition, it adopts a novel fuzzy gradient-adaptive quantization scheme. The proposed coding technique possesses superior performance over its non-fuzzy counterparts especially at low bit quantization. This is due to the inherent adaptivity in the fuzzy prediction methodology as well as the gradient-adaptive quantization scheme. Simulation results are provided to demonstrate the efficient performance of the proposed fuzzy predictive coding system.","PeriodicalId":337983,"journal":{"name":"The IEEE Region 8 EUROCON 2003.

Pulse current source with high dynamic 高动态脉冲电流源

Voncina","doi":"10.1109/EURCON.2003.1248203","DOIUrl":"https://doi.org/10.1109/EURCON.2003.1248203","url":null,"abstract":"The paper presents a new topology of the pulse current source required in contemporary electrochemical processes (e.g. pulse plating). The main design challenge is generation of pulses with current slopes (di/dt) as high as possible. A buck converter is the most appropriate topology for generation of a constant current, but it doesn't fulfill the demands for a dynamic operation. The slope of the pulsed load current can be essentially improved if two or more converters are connected in series or parallel according to U. Lettau (1993). A complex control algorithm and interdependence between the slope of the pulse current and its ripple in the steady state are the main disadvantages of such connection. These two drawbacks are bypassed with a proposed topology of the pulse current source. The source consists of the input buck converter and the bridge inverter with a current fed transformer. The function of the bridge inverter differs from the usual bridge operation. The operating mode, in which the energy is carried to the load, is called transfer mode. The idle mode is the other possible mode in which all transistors in the bridge are turned on at the same time and the load current is zero. The load current is controlled indirectly by the DC input current (i/sub L/). Since the main inductor is placed into a DC link, the slope of the output current is limited only by stray inductances of the transformer and load. Stray inductances slow down commutation process, which is reflected in over-voltages on the bridge transistors. In order to avoid the destruction of those transistors, a clamping diode D/sub Z/ is added in the input circuit. Additional advantages of the proposed topology are isolated output stage and modularity. Experimental results obtained from a laboratory pulse current source confirm an outstanding dynamic performance.","PeriodicalId":337983,"journal":{"name":"The IEEE Region 8 EUROCON 2003.
