  • Patent number: 7668716
    Abstract: A device improves speech recognition accuracy by utilizing an external knowledge source. The device receives a speech recognition result from an automatic speech recognition (ASR) engine, the speech recognition result including a plurality of ordered interpretations, wherein each of the ordered interpretations includes a plurality of information items. The device analyzes and filters the plurality of interpretations using an external knowledge source to create a filtered plurality of ordered interpretations. The device stores the filtered plurality of ordered interpretations to a memory. The device transmits the filtered plurality of ordered interpretations to a dialog manager module to create a textual output. Alternatively, the dialog manager module retrieves the filtered plurality of ordered interpretations from a memory.

  • Patent number: 4346423
    Abstract: A circuit and process for disconnecting the current from the operating gap of an electrolytic processing device in the event of a short circuit in which a signal is produced from the AC current in the transformer supplying power to the gap, such signal indicating the gap current, the maximum value of that signal is stored for successive time periods and the stored value for a preceding period compared with the present signal to operate a switch in the current supply to the gap when a short circuit condition is detected.
