Abstract: A voice input and output apparatus is comprised of a voice output section that produces a sound field by outputting a sound on the basis of a voice output signal. A voice signal control section derives a calculation expression of a filtering process on the basis of a space transfer characteristics between the voice output section and control points. The voice signal control section produces the voice output signal by executing the filtering process of a voice input signal, so that a balance among sound pressures at predetermined control points in the sound field takes a predetermined balance.

Abstract: A sound input device has: a start-of-a-learning-operation determining unit configured to determine a time when a filter is started to be learned, the filter being for removing noise from sound signals detected in a car compartment while leaving object signals; and a frequency band determining unit configured to determine a frequency band for which the filter is learned after the time when the filter is started to be learned is determined.

Abstract: A sound field controller forms a predetermined sound field in a predetermined environment in a manner that control sounds are previously stored for each environment, the control sounds which have been designed to form a predetermined observation sound at a predetermined control point, thereafter, a control sound which corresponds to an observation sound requested to be outputted and also corresponds to a detected environment is selected from the previously stored control sounds, and subsequently, a sound output unit is allowed to output the selected control sound.

Abstract: A map image display device, a map image display method and a map image display program are disclosed. Upon determination of a map image for an objective to be displayed in response to a user's command input, a standard surface area setting unit 21 divides a surface area of a whole area shown in the map image to be displayed into n equal divisions to assign resulting values to standard surface areas. Then, a particular designation selecting unit 16 selects n pieces of relevant particular designations of areas, whose surface areas are closer to the standard surface areas, among areas involved in the map image for the objective to be displayed. A display image preparing unit 17 prepares image data to cause the selected n pieces of the relevant particular designations to be displayed on the map image as icons, and a display control unit 18 controllably drives the display unit based on image data.

Abstract: An aspect of the present invention provides a voice recognition system includes that a memory unit configured to store a statistical language dictionary which statistically registers connections among words, a voice recognition unit configured to recognize an input voice based on the statistical language dictionary, a prediction unit configured to predict, according to the recognition result provided by the voice recognition unit, connected words possibly voiced after the input voice, and a probability changing unit configured to change the probabilities of connected words in the statistical language dictionary according to the prediction result provided by the prediction unit, wherein the voice recognition unit recognizes next input voice based on the statistical language dictionary changed by the probability changing unit and wherein the memory unit, the voice recognition unit, the prediction unit and the probability changing unit are configured to be installed in the mobile unit.
