Abstract: An onboard device estimates a traveling state of a vehicle that may be influenced by the psychological state of a driver, based on an utterance of the driver without the use of various sensors, and includes: a voice collection unit for collecting a driver's voice; a traveling state collection unit for collecting traveling state information representing a traveling state of a vehicle; a database generation unit for generating a database by associating voice information corresponding to the collected voice with the collected traveling state information; a learning unit for learning an estimation model, with pairs including the voice information and the traveling state information recorded in the generated database being used as learning data; and an estimation unit for estimating the traveling state of the vehicle that may be influenced by a psychological state of the driver by using the estimation model, based on an utterance of the driver.

Abstract: Interaction response promptness is ensured in a hybrid voice interaction system. A voice interaction terminal includes a keyword recognition unit which recognizes a predetermined keyword from a voice uttered by a user and a response sentence generation unit which generates a first response sentence on the basis of the keyword. A voice interaction server includes a voice recognition unit which recognizes voice data sent from the voice interaction terminal and an interaction management unit which generates a second response sentence on the basis of a voice recognition result and manages the keyword to be recognized by the keyword recognition unit on the basis of a predetermined interaction scenario. The hybrid voice interaction system further includes an output unit which outputs the first response sentence generated by the response sentence generation unit or the second response sentence sent from the voice interaction server.

Abstract: A speech recognition apparatus includes a speech detection unit configured to detect a speech input by a user, an information providing unit configured to perform information provision to the user, using either first speech recognition information based on a recognition result of the speech by a first speech recognition unit or second speech recognition information based on a recognition result of the speech by a second speech recognition unit different from the first speech recognition unit, and a selection unit configured to select either the first speech recognition information or the second speech recognition information as speech recognition information to be used by the information providing unit on the basis of an elapsed time from the input of the speech, and change a method of the information provision by the information providing unit.

Abstract: To assign an appropriate pronunciation to a word or phrase having a unique pronunciation or a word or phrase having a pronunciation incorrectly used by a user, a terminal device divides a first word or phrase indicated by a first recognition result acquired from a speech recognition server into morphemes and assigns a pronunciation to each of the morphemes, and divides a second word or phrase indicated by a second recognition result acquired from a speech recognition module into morphemes. Further, the terminal device selects, for a morpheme having the same character string as that of any one of the morphemes forming the second word or phrase among the morphemes forming the first word or phrase, a pronunciation of the morpheme indicated by the second recognition result.

Abstract: A flasher type fish finder has: a motor with a rotary shaft having play in an axial direction; a display rotating disk fixed to the rotary shaft; a first installation part; and a second installation part fixed to a member not influenced by the play. In the first installation part, a magnet or a ferromagnetic material is on the rotary shaft or the display rotating disk such that the center of gravity is at the rotary shaft center. In the second installation part, a magnet or a ferromagnetic material is provided occurring an attraction force or a repulsive force in the axial direction, for the magnet or the ferromagnetic material of the first installation part. The magnet is in at least one of the first installation part and the second installation part. The surfaces of a first magnetic pole and a second magnetic pole are orthogonal to the rotary shaft.

Abstract: A searchlight sonar is installed on a ship (11) and searches under water around the ship (11) while changing the transmitting direction of an ultrasonic beam (TB) at a predetermined split rotation (Mn) in the circumferential direction around the ship (11). The split rotation (Mn) is set to increase as the depression angle of the transmitting direction of the ultrasonic beam (TB) is increased.

Abstract: An information retrieving apparatus is provided which has excellent usability using voice inputs. Search queries input by a user via a touch panel or the like are used as voice recognition vocabulary. Further, the search queries are edited by use of morpheme information and/or other information in a database, thereby providing such voice recognition vocabulary that can be easily uttered by the user.

Abstract: The present invention provides a technique, by speech input, to specify a location, even when a name or the like of the location is not accurately known, while driving. An in-vehicle apparatus mounted in a vehicle has a speech recognition function, and stores information shown on a signboard and a noun substitute in storage. If speech inputted from a speech input device includes a noun substitute and further includes at least a part of the information shown on the signboard, a response is decided according to the information shown on the signboard, and the decided response is outputted from an output device.

Abstract: It is provided a speech recognition system installed in a terminal coupled to a server via a network. The terminal holds map data including a landmark. The speech recognition system manages recognition data including a word corresponding to a name of the landmark, and sends update area information and updated time to the server. The server generates, when recognition data of the area of the update area information sent from the terminal has been changed after updated time, difference data between latest recognition data and recognition data of the update area information at a time of the updated time, and sends the generated difference data and map data of the update area information to the terminal. The terminal updates the map data based on the map data sent from the server. The speech recognition system updates the recognition data managed by the terminal based on the difference data.
