    摘要: The present invention relates to extended release pharmaceutical compositions of Levetiracetam and processes for preparing the same. The extended release tablet of Levetiracetam is with a core comprising of Levetiracetam and water dispersible rate controlling polymer, and the tablet core is optionally functional coated comprising a combination of water non-dispersible and/or water dispersible polymer. It provides extended therapeutically effective plasma levels over a twenty four hour period with diminished incidences of neuropsychiatric adverse events by eliminating the troughs and peaks of drug concentration in a patient's blood plasma. The composition also exhibits no food effect.

    摘要: For improving the accuracy of a speech recognition system, for the specific task of speech-to-text (dictation style speech) translation, a constrained dictation methodology using speak-and-spell mode is disclosed. The invention is perfectly suited for modern day “text-messaging” applications wherein the number of words being dictated is very small (limited by the 140-160 characters message length constraint). Additionally, the invention adds a control on the way users interact with machines, thereby making the speech recognition task easier and improving system accuracy.
