Abstract: The object of the present invention is to provide a voice recognition technique that can handle wording in other languages. The voice recognition dictionary data construction apparatus includes an attribute setting unit that sets attributes to first words that constitute a first character string representing a place name in the first language, a language conversion unit that creates a second character string by replacing the first words in the first character string with the second words without changing the attributes thereof, an order changing unit that creates a third character string by changing the word order of the second character string based on the attributes of the words of the second character string and the word order rule of place names of the second language, a phoneme data construction unit that constructs the phoneme data of the third character string.

Abstract: An object is to provide a technique that allows voice recognition of voice including a plurality of languages while suppressing a data size of a voice recognition dictionary. A voice recognition dictionary includes a plurality of place name dictionaries and a plurality of house number dictionaries in which phonemes in a different language are mapped to phonemes in a corresponding language. Out of the plurality of place name dictionaries, one place name dictionary is set, which a language-specific voice recognition unit set by a voice recognition language setting unit may perform voice recognition in phonemes of the corresponding language, and out of the plurality of house number dictionaries, one house number dictionary is set, which the language-specific voice recognition unit may perform voice recognition by substituting phonemes in a different language for the phonemes in the corresponding language.

Abstract: According to a voice recognition device of this invention, with respect to a keyword extracted by a voice recognition unit from a speech content by a user, display contents each displayed by an operation by the user and their respective numbers of display times are stored as history information, and a search level is set through determination of whether or not the same operations and displays have been made by a predetermined number of times or more. This makes it possible, at the next time the same keyword is extracted, to immediately present information of such a level that the user requires, and thus, detailed information necessary for the user can always be provided efficiently, so that the convenience of the user is enhanced.

Abstract: A voice recognition device includes a vehicle state detecting unit for detecting a vehicle state of a vehicle having the voice recognition device mounted thereon, and an acoustic data matching unit for matching an acoustic feature value converted by a sound analyzing unit with a recognition dictionary stored in a recognition dictionary storage unit to recognize a voice input to a microphone. The device also includes a recognition parameter setting unit for setting a recognition parameter at the time when the voice input to the microphone is recognized, and a control unit for instructing the recognition parameter setting unit to change the recognition parameter when the vehicle state detected by the vehicle state detecting unit satisfies a predetermined condition.

Abstract: A recognition dictionary creating device includes a user dictionary in which a phoneme label string of an inputted voice is registered and an interlanguage acoustic data mapping table in which a correspondence between phoneme labels in different languages is defined, and refers to the interlanguage acoustic data mapping table to convert the phoneme label string registered in the user dictionary and expressed in a language set at the time of creating the user dictionary into a phoneme label string expressed in another language which the recognition dictionary creating device has switched.

Abstract: A voice recognition device 100 includes: a vehicle state detecting unit 7 for detecting a vehicle state of a vehicle having the voice recognition device mounted thereon; an acoustic data matching unit 5 for matching an acoustic feature value converted by a sound analyzing unit 3 with a recognition dictionary stored in a recognition dictionary storage unit 4 to recognize a voice input to a microphone 1; a recognition parameter setting unit 10 for setting a recognition parameter at the time when the voice input to the microphone 1 is recognized; and a control unit 9 for instructing the recognition parameter setting unit 10 to change the recognition parameter when the vehicle state detected by the vehicle state detecting unit 7 satisfies a predetermined condition.

Abstract: A voice recognition apparatus creates a voice recognition dictionary of words which are cut out from address data constituting words that are a voice recognition target, and which have an occurrence frequency not less than a predetermined value, compares a time series of acoustic features of an input voice with the voice recognition dictionary, selects the most likely word string as the input voice from the voice recognition dictionary, carries out partial matching between the selected word string and the address data, and outputs the word that partially matches as a voice recognition result.

Abstract: An information apparatus for use in mobile unit, which is mounted on a mobile unit, includes a broadcast receiver receiving a signal containing a station name; a recognition dictionary registering the station name; and a recognition section that, referring to the dictionary, tunes to the station associated with the station name. The apparatus further includes a recognition dictionary update section updating the dictionary in response to signal reception; and a dictionary update deciding section that decides, based on the update mode of the dictionary during updating, if any change occurs between the station transmitting the signal and the update mode, and alters, if change occurs, an update frequency of the dictionary by the dictionary update section in response to a traveling condition of the mobile unit or to a receiving condition of the signal.

Abstract: Disclosed is a voice recognition device which creates a recognition dictionary (statically-created dictionary) in advance for a vocabulary having words to be recognized whose number is equal to or larger than a threshold, and creates a recognition dictionary (dynamically-created dictionary) for a vocabulary having words to be recognized whose number is smaller than the threshold in an interactive situation.

Abstract: A car navigation system is provided with a voice recognition capability to search position information by voice recognition without requiring registration of voice recognition standard patterns for words to be recognized. Acoustical analysis of users speech is compared with stored acoustic models to obtain a relevant scanned recognition string. The sound recognition string is used to obtain position information which is supplied to the navigation device.

Abstract: In a magnetic recording device for magnetically recording Information on a magnetic recording medium by a magnetic head, the magnetic head is so oriented that the magnetic flux leaking at the head gap is at right angles with the direction of relative movement between the magnetic head and the magnetic recording medium and parallel with the surface of the magnet recording medium. The magnetic recording medium may have track portions formed of a magnetic material, and intertrack portions formed of a nonmagnetic material. The magnetic recording medium may alternatively be formed of convex track portions and concave intertrack portions.
