Inventor: COHRS PAUL WESLEY
IPC: G10L15/10
Filed: 1996-07-03
Abstract: A method and apparatus for speech recognition in which a single criterion or set of criteria is selected manually by the user, from plural classes of recognition criteria. The stored classes of recognition criteria include a default class optimized for an average user in normal conditions, at least one class having a probability of recognition greater than said default class, and at least one class having a probability of recognition less than said default class. Accordingly, the user may select that class of criteria which provides the best results for him or her, as measured by greater accuracy (fewer false positive detections) or fewer instances of non-rejection.      An utterance is compared to one or more models of speech to determine a similarity metric for each such comparison. The model of speech which most closely matches the utterance is determined based on the one or more similarity metrics. The similarity metric corresponding to the most closely matching model of speech is analyzed to determine whether the similarity metric satisfies the criteria of the user-selected class. The present application has application to many problems in speech recognition including isolated word recognition and command spotting. Illustrative embodiments of the invention in the context of telecommunications instruments are provided.

Title: Diversity receiver and its control method
Inventor: HIGUCHI KENICHI
IPC: H04B1/707
Filed: 1996-11-28
Abstract: Enabling reception quality to be improved and the capacity in terms of the number of simultaneous users in a cell to be increased, and speeding up the establishment of spreading code synchronization and the convergence of weighted coefficients, by feedback controlling weighted coefficients such that desired signal power to interference power ratio (SIR) becomes maximum. A coherent adaptive diversity configuration is employed to which absolute coherent detection is applicable.      Adaptively feeding weighted coefficients back to diversity branches makes it possible to reduce the influence of the interference power from other users, and thus to increase the capacity in terms of the number of simultaneous users in the cell.      Furthermore, the direction that provides the maximum received SIR is determined while rotating antennas in a state of having directivity with a predetermined angle range. Setting initial values of the weighted coefficients at values corresponding to that direction enables the weighted coefficients to converge quickly.            ~~~~

Abstract: A method for creating a compressed digital representation of an image involves locating areas in uncompressed image data in which increased resolution is desired and taking a wavelet transform of the uncompressed image data. The transformed data is then quantized. Quantization is finer in regions of the transformed data which correspond to the areas in which increased resolution is desired and coarser in other areas. The quantized data is then encoded and saved. The method has particular application in compressing images of human faces for use in electronic ID cards and the like. Recognizable images can be reconstructed from the compressed digital representation even at very high compression ratios.
