  • Patent number: 7676364
    Abstract: 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.

  • Publication number: 20090136754
    Abstract: An article includes (a) a glass substrate having a modified surface that comprises a glass surface and a layer of nanoscale inorganic oxide particles disposed in contact with and bound to at least a portion of the glass surface, and (b) a polymer layer disposed in contact with and bound to the modified glass surface. A method for improving the hydrolytic stability of an interface of a glass surface and a polymer surface, includes the step of, prior to forming the interface of the glass surface and the polymer surface, treating at least a portion of the glass surface with nanoscale inorganic oxide particles to modify the glass surface by depositing a quantity of such particles on the portion of the surface.

  • Publication number: 20070092569
    Abstract: 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.

  • Patent number: 7003456
    Abstract: A computer-based method of routing a message to a system includes receiving a message, and processing the message using large-vocabulary continuous speech recognition to generate a string of text corresponding to the message. The method includes generating a confidence estimate of the string of text corresponding to the message and comparing the confidence estimate to a predetermined threshold. If the confidence estimate satisfies the predetermined threshold, the string of text is forwarded to the system. If the confidence estimate does not satisfy the predetermined threshold, the information relating to the message is forwarded to a transcriptionist. The message may include one or more utterances. Each utterance in the message may be separately or jointly processed. In this way, a confidence estimate may be generated and evaluated for each utterance or for the whole message. Information relating to each utterance may be separately or jointly forwarded based on the results of the generation and evaluation.

  • Publication number: 20050203742
    Abstract: For improving the accuracy of a speech recognition system, for the specific task of character recognition, the character that is to be recognized or interpreted, is spoken in accordance with this invention, using simple coding-schemes that result in acoustic renderings that are well separated in the acoustic space. Furthermore, to relax the constraint on users for memorizing multiple words associated with multiple characters, in one embodiment, the coding-schemes are defined based on a combination of the given character and its neighboring/succeeding character(s).
