The speech recognition result through the general-purpose server and that through the specialized speech recognition server are integrated in an optimum manner, thereby, a speech recognition function least in errors in the end being provided. The specialized speech recognition serveris constructed with the words contained in the user dictionary data in use as well as the performance of the general-purpose speech recognition serveris preliminarily evaluated with such user dictionary data. Based on such evaluation result, information related to which recognition results through the specialized and general-purpose speech recognition servers are adopted and to how the adopted recognition results are weighted to obtain an optimum recognition result is preliminarily retained in the form of a database. Upon executing recognition, an optimum recognition result is obtained by comparing the recognition results through the specialized and general-purpose servers with the parameter for recognition result integration

An object of the present invention is to provide a technique of an information terminal that allows more efficient utilization of high-level searching functions. The information terminal is provided with an audio input accepting unit to accept an input of speech information, a communication unit to establish communication with a predetermined server device via a network, an output unit, a POI specifying unit to transmit the speech information accepted by the audio input accepting unit to the server device and receive information specifying a candidate of a POI (Point Of Interest) associated with the speech information, a POI candidate output unit to output to the output unit, the information specifying the candidate of the POI received by the POI specifying unit, and a route searching unit to accept a selective input of the information specifying the candidate of the POI, and search for a route directed to the POI.

Information terminal, server device, searching system, and searching method thereof

A voice data transferring device intermediates between an in-vehicle terminal and a voice recognition server. In order to check a change in voice recognition performance of the voice recognition server, the voice data transferring device performs a noise suppression processing on a voice data for evaluation in a noise suppression module; transmits the voice data for evaluation to the voice recognition server; and receives a recognition result thereof. The voice data transferring device sets a value of a noise suppression parameter used for a noise suppression processing or a value of a result integration parameter used for a processing of integrating a plurality of recognition results acquired from the voice recognition server, at an optimum value, based on the recognition result of the voice recognition server. This makes it possible to set a suitable parameter even if the voice recognition performance of the voice recognition server changes.

The invention provides a conversational speech analyzer which analyzes whether utterances in a meeting are of interest or concern. Frames are calculated using sound signals obtained from a microphone and a sensor, sensor signals are cut out for each frame, and by calculating the correlation between sensor signals for each frame, an interest level which represents the concern of an audience regarding utterances is calculated, and the meeting is analyzed.

In an information storage device in which small partitions for storing information are three-dimensionally placed inside a solid, the invention aims at long-period storage, robustness, and rapid information reading. Accordingly, the stored three-dimensional information is divided into two-dimensional data for each layer, and two-dimensional inverse Fourier transform is previously applied for the two-dimensional data. The two-dimensional data is recorded in each layer in a Z direction inside a storage medium which is solid. When the information is reproduced, electromagnetic waves are irradiated to a storage area MA as gradually rotating the storage area MA around a z axis, and projection images of all layers during the rotation are obtained from response. By applying one-dimensional Fourier transform for a plurality of projection images obtained as described above, the recorded original three-dimensional information is rapidly reproduced.

Information processor device and storage medium

The present invention provides elimination of atmosphere that is not suitable to a space concerned by controlling atmosphere. The present invention is characterized that atmosphere in space is analyzed based on voice, and if atmosphere that is not suitable to the space is detected, the atmosphere in the space is controlled by choosing and irradiating illumination that enables to create atmosphere suitable to the space, atmosphere in the space is controlled for creating atmosphere that is suitable to the space.

A method of providing an interpretation service, is disclosed. The method includes the steps of receiving an incoming telephone call from a user, forming a plurality of databases, wherein the plurality of databases includes at least one sentence registered to individual user, receiving at least one user information item via the incoming telephone call, searching at least one of the plurality of databases for at least one sentence correspondent to the at least one information item, outputting, according the step of searching, a translation, from at least one of the plurality of databases, of the at least one sentence correspondent to the at least one information item, and outputting, in audio on the incoming telephone call, the translation of the at least one sentence correspondent to the at least one information item.

Method and apparatus for language translation using registered databases

Provided is a crisis monitoring system that detects a crisis by identifying a person's emotion from his/her utterance includes an input unit to which an audio signal is inputted, a recording unit which records information necessary to judge a crisis situation, and a control unit which controls the input unit and the recording unit. The recording unit records emotion attribute information, which includes a feature of a specific emotion in an audio signal, and the control unit determines a person's emotion by comparing an audio signal inputted to the input unit with the emotion attribute information, and executes a predetermined emergency processing when it is judged that the determined emotion indicates a crisis situation.

Crisis monitoring system

A speech interpretation server, and a method for providing a speech interpretation service, are disclosed. The server includes a speech input for receiving an inputted speech in a first language from a mobile terminal, a speech recognizer that receives the inputted speech and converts the inputted speech into a prescribed symbol string, a language converter that converts the inputted speech converted into the prescribed symbol string into a second language, wherein the second language is different from the first language, and a speech output that outputs the second language to the mobile terminal. The method includes the steps of providing an interpretation server having resident thereon a plurality of registered sentences to be interpreted, activating a translation connection between the mobile terminal and the interpretation server, receiving speech, in a first language, inputted to the mobile terminal via the translation connection, at the interpretation server, recognizing and interpreting the speech inputted based on a comparison of the inputted speech to the plurality of registered sentences to be interpreted, and outputting a translation correspondent to the second language.

An interpretation service for voice based on sentence template retrieval allows a translation database to be customized without burdening users and enables sentences needed by users to be accurately interpreted. A sentence to be stored in a translation database for customization can be described as a sentence template including a slot which allows words to be replaced. A condition for selecting sentence templates is extracted from a registered user profile (UP). A sentence template matching the condition is retrieved from those stored in the translation database for customization and is registered in a translation database customized for each user. A word extracted from the UP is inserted into the sentence template's slot for registration to a sentence dictionary customized for each user.
