  • Publication number: 20180277106
    Abstract: According to an embodiment, a verification system includes a storage controller, first and second receivers, a comparator, a response constructor, a response generator, and an output controller. The storage controller stores, in a storage, first response data and first situation data associated with the first response data. The first receiver receives second response data. The comparator determines a similarity between second situation data indicating a second context for using the second response data and the first situation data. The response constructor constructs response content information comprising the second response data and the first response data associated with the first situation data having the similarity equal to or greater than a threshold. The second receiver receives speech data. The response generator generates a response sentence corresponding to the speech data using the response content information. The output controller outputs for display one or more response sentences.

  • Publication number: 20180277109
    Abstract: According to one embodiment, an edit assisting system includes a server device and a client device. The client device displays a first object, which indicates first speech of a user and a first portion of the first speech, and a second object, which indicates second speech generated by the server device and a second portion of the second speech, on a screen based on a scenario indicated in scenario data. The first and second portions are editable. The client device transmits edit data indicating the first portion which is edited and/or the second portion which is edited to the server device.

  • Publication number: 20180012734
    Abstract: A substrate processing device includes a housing connected to ground, a cathode stage that supports a substrate, an anode unit, and a gas feeding unit that feeds gas toward the first plate. The cathode stage is applied with voltage for generating plasma. The anode unit includes a first plate including first through holes and a second plate including second through holes that are larger than the first through holes. The second plate is located between the first plate and the cathode stage. The first plate produces a flow of the gas through the first through holes. The gas that has passed through the first through holes flows through the second through holes into an area between the second plate and the cathode stage. A distance between the first plate and the second plate is 10 mm or greater and 50 mm or less.

  • Publication number: 20170162190
    Abstract: According to one embodiment, an apparatus includes a storage unit, a first acquisition unit, a second acquisition unit, an analyzer, and a recognition unit. The storage unit stores first situation information about a situation assumed in advance, a first representation representing a meaning of a sentence assumed, intention information representing an intention to be estimated, and a first value representing a degree of application of the first representation to the first situation information and the intention information. The first acquisition unit acquires a natural sentence. The second acquisition unit acquires second situation information about a situation when acquiring the natural sentence. The analyzer analyzes the natural sentence and generates a second representation representing a meaning of the natural sentence. The recognition unit obtains an estimated value based on the first value associated with the first situation information and the first representation.

  • Publication number: 20170161665
    Abstract: According to an embodiment, a dialogue data collection system includes a presenter, a determiner, a notifier and a collector. The presenter receives response information that the dialogue management apparatus generates by advancing a dialogue status based on the spoken phrases, and presents the response information to the worker. The determiner compares the response information to one or more achievement conditions predetermined relative to the task, and determines achievement or non-achievement of the task based on whether or not the achievement conditions are satisfied. The notifier notifies the worker of achievement of the task. The collector collects dialogue data including the spoken phrase and the response information.

  • Publication number: 20130080161
    Abstract: According to one embodiment, a speech recognition apparatus includes following units. The service estimation unit estimates a service being performed by a user, by using non-speech information, and to generate service information. The speech recognition unit performs speech recognition on speech information in accordance with a speech recognition technique corresponding to the service information. The feature quantity extraction unit extracts a feature quantity related to the service of the user, from the speech recognition result. The service estimation unit re-estimates the service by using the feature quantity. The speech recognition unit performs speech recognition based on the re-estimation result.
