20110282925 | DIRECTIONAL OPTIMIZATION VIA EBW - An optimization system and method includes determining a best gradient as a sparse direction in a function having a plurality of parameters. The sparse direction includes a direction that maximizes change of the function.

An extended Baum Welch (EBW) method can be used to identify the sparse direction. A best step size is determined along the sparse direction by finding magnitudes of entries of direction that maximizes the function restricted to the sparse direction. A solution is recursively refined for the function optimization using a processor and storage media. | 11-17-2011 |

20120016674 | Modification of Speech Quality in Conversations Over Voice Channels - Techniques are disclosed for modifying speech quality in a conversation over a voice channel. For example, a method for modifying a speech quality associated with a spoken utterance transmittable over a voice channel comprises the following steps. The spoken utterance is obtained prior to an intended recipient of the spoken utterance receiving the spoken utterance. An existing speech quality of the spoken utterance is determined. The existing speech quality of the spoken utterance is compared to at least one desired speech quality associated with at least one previously obtained spoken utterance to determine whether the existing speech quality substantially matches the desired speech quality. At least one characteristic of the spoken utterance is modified to change the existing speech quality of the spoken utterance to the desired speech quality when the existing speech quality does not substantially match the desired speech quality. The spoken utterance is presented with the desired speech quality to the intended recipient. | 01-19-2012 |

The test vector is mapped with the selected subset of the training data set as a linear combination that is weighted by a sparseness constraint such that a new test feature set is formed wherein the training data set is moved more closely to the test vector subject to the sparseness constraint. An acoustic model is trained on the new test feature set. | 03-29-2012 |

20120253783 | OPTIMIZATION OF NATURAL LANGUAGE PROCESSING SYSTEM BASED ON CONDITIONAL OUTPUT QUALITY AT RISK - Techniques are disclosed for optimizing results output by a natural language processing system. For example, a method comprises optimizing one or more parameters of a natural language processing system so as to improve a measure of quality of an output of the natural language processing system for a first type of data processed by the natural language processing system while maintaining a given measure of quality of an output of the natural language processing system for a second type of data processed by the natural language processing system. For example, the first type of data may have a substantive complexity that is greater than that of the second type of data. Thus, when the natural language processing system is a machine translation system, use of a conditional value at risk metric for the translation quality provides for a high quality output of the machine translation system for data of a high substantive complexity (for sophisticated users) while maintaining an average quality output for average data (for average users). | 10-04-2012 |
