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.

Voice recognition dictionary data construction apparatus and voice recognition apparatus

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.

Voice recognition apparatus and voice recognition method

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.

Voice recognition device

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.

Voice recognition device and navigation device

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.

Recognition dictionary creating device, voice recognition device, and voice synthesizer

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.

Adaptive recognition dictionary update apparatus for use in mobile unit with a tuner

A voice recognition unit is constructed in such a way as to create a voice label string for an inputted voice uttered by a user inputted for each language on the basis of a feature vector time series of the inputted voice uttered by the user and data about a sound standard model, and register the voice label string into a voice label memorywhile automatically switching among languages for a sound standard model memoryused to create the voice label string, and automatically switching among the languages for the voice label memoryfor holding the created voice label string by using a first language switching unit SWand a second language switching unit SW
