20090083036 | Unnatural prosody detection in speech synthesis - Described is a technology by which synthesized speech generated from text is evaluated against a prosody model (trained offline) to determine whether the speech will sound unnatural. If so, the speech is regenerated with modified data. The evaluation and regeneration may be iterative until deemed natural sounding. For example, text is built into a lattice that is then (e.g., Viterbi) searched to find a best path. The sections (e.g., units) of data on the path are evaluated via a prosody model. If the evaluation deems a section to correspond to unnatural prosody, that section is replaced, e.g., by modifying/pruning the lattice and re-performing the search. Replacement may be iterative until all sections pass the evaluation. Unnatural prosody detection may be biased such that during evaluation, unnatural prosody is falsely detected at a higher rate relative to a rate at which unnatural prosody is missed. | 03-26-2009 |

20120265512 | UPDATING GEOLOGICAL FACIES MODELS USING THE ENSEMBLE KALMAN FILTER - The invention relates to a method for history matching a facies geostatistical model using the ensemble Kalman filter (EnKF) technique. The EnKF is not normally appropriate for discontinuous facies models such as multiple point simulation (MPS). In the method of the invention, an ensemble of realizations are generated and then uniform vectors on which those realizations are based are transformed to Gaussian vectors before applying the EnKF to the Gaussian vectors directly.

The uniform vectors may be vectors on which the realizations are based directly; alternatively each realization may be based on a plurality of uniform vectors linearly combined with combination coefficients. In this case each realization is associated with a uniform vector made up from the combination coefficients, and the combination coefficient vector is then transformed to Gaussian and updated using EnKF. | 10-18-2012 |

The KL expansion may be used to produce amended realizations for history matching and is widely used. However, it is necessary in order to use the KL expansion to perform singular value decomposition of the covariance matrix of the model to provide eigenvectors and eigen values for use in the expansion. In a typical geostatistical model, the covariance matrix is too large for singular value decomposition to be performed. Prior solutions to this problem involved reducing the resolution of the model so as to reduce the size of the covariance matrix. In the method described, a plurality of random realizations are generated and an approximation of the covariance matrix is constructed from the realizations, the approximation matrix having smaller dimensions than the true covariance matrix. | 12-20-2012 |
