Title: The method and apparatus for recognizing voice
Inventor: JEON HYUNG BAE
IPC: G10L15/02
Filed: 2007-09-19
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.

Abstract: The contact between, for example, ascending liquid droplets of lighter liquid, as the dispersed phase, and heavier liquid, as the continuous phase, flowing across perforated trays in a flooded liquid/liquid contacting column, is enhanced by providing upstanding baffles on lower trays, interspersed with depending baffles from the trays above. The baffles cause the heavy liquid to flow along an undulating path. Flow distributing partitions extend along the undulating flow path, between the baffles, to distribute liquid flow across the trays. The roles of the lighter liquid and the heavier liquid may be reversed as phases.
