Abstract: A position-based routing method by using a cell in a wireless sensor network is provided to minimize the energy and to determine a path until a destination node easily by reducing the periodical communication for the position information confirmation. In a next-hop position calculation process, the virtual ONI(Optimal Next-hop Information) among the paths until the destination node is calculated. In a communication area division process(302), the communication area is divided into fixed cell sizes by using the calculated virtual ONI position. In a packet broadcasting process(303), a packet including the virtual ONI position and the cell sizes is broadcasted to the surrounding node in the communication area. In a next-hop node decision process(305), the firstly transmitted surrounding node is determined as the next-hop node after receiving a response message in regard to the broadcasted packet from the surrounding node. In the next-hop position calculation process, the position joined by the virtual segment for connecting the distance until the destination node and a virtual circle corresponding to one's own communication area is calculated and the calculating result is determined as the next hop position.

Abstract: A vocabulary decoding method and an apparatus thereof are provided to shorten overall performance time of voice recognition without deteriorating voice recognition performance. Based on an inputted voice signal, length of a phoneme series which is outputted by decoding phonemes is detected. Based on the detected length of the phoneme series, recognition target words(202) similar to the length of the phoneme series are selected. Edition distance measurement with the phoneme series is carried out on the basis of the selected recognition target words. Through the edition distance measurement, at least one recognition target word having a minimum edition distance with the phoneme series is outputted.

Abstract: A voice recognition method and an apparatus thereof are provided to calculate the reliability on a grapheme string of recognized grapheme, and improve the voice recognition performance by using the reliability. A phoneme interval detecting unit(404) analyzes voice feature data outputted from a voice feature extracting unit(402), and then determines the boundary between phonemes to detect a phoneme interval. A reliability decision unit(406) compares the pattern of the detected phoneme intervals with phonemes belonging to a pre-defined phoneme model(416) to calculate the similarity. A reliability-based phoneme error model(418) stores the phoneme recognition probability distribution which is obtained by training whether an inputted voice phoneme is recognized as any kind of phoneme, in advance.
