Even when a copying machine with a voice guidance function is used, a problem of wastefully copying wrong documents or documents with missing pages remains unsolved for visually impaired persons. To this end, a document image is read, character strings on the read document image are recognized, a character string indicating the contents of the document is chosen from the recognized character strings, the chosen character string is converted into speech, and synthetic speech is output.

Method, apparatus and program for recognizing, extracting, and speech synthesizing strings from documents

Disclosed are an interactive system and method of controlling the same for achieving a task more efficiently. Items of data to be searched are stored in a memory () in a form classified according to prescribed classes, and a dialog controller () decides the order in which questions are presented to a user in order to narrow down the object of a search to data in a specific class. The questions are then presented to the user in the decided order by a question generator ().

Modality information indicating various functions of a multimodal document reception processing apparatus is transmitted to a multimodal document transmission apparatus, and a multimodal document, which is generated by the multimodal document transmission apparatus based on the modality information is received. A speech synthesis unit synthesizes speech of text data to be output as speech in the multimodal document, and a speech output unit outputs the synthesized output speech. A GUT display unit displays text data to be displayed in the multimodal document.

Input form information associated with an input form is stored in a form name holding unit. Input speech is recognized by a speech recognition unit, and input form information corresponding to that speech recognition result is selected. The display pattern of an input form corresponding to the selected input form information is controlled by a GUI display unit.

A user dictionary, which is formed by storing pronunciations and notations of target recognition words designated by the user in correspondence with each other, input speech recognition data, and dictionary management data used to determine the recognition field of a recognition dictionary used in recognition of the speech recognition data are sent to a server via a communication module. In the server, a dictionary management unit looks up an identifier table to determine a recognition dictionary corresponding to the dictionary management information received from a client from a plurality of kinds of recognition dictionaries. A speech recognition module recognizes the speech recognition data using at least the determined recognition dictionary. The recognition result is sent to the client via a communication module.

The system implements high-accuracy speech recognition while suppressing the amount of data transfer between the client and server. For this purpose, the client compression-encodes speech parameters by a speech processing unit, and sends the compression-encoded speech parameters to the server. The server receives the compression-encoded speech parameters, a speech processing unit makes speech recognition of the compression-encoded speech parameters, and sends information corresponding to the speech recognition result to the client.

Client-server speech processing system, apparatus, method, and storage medium

An information processing apparatus inputs a document having a plurality of input fields, and displays it using a display control item. The apparatus then determines whether or not one of the plurality of input fields is designated by the user. Specific grammar corresponding to the designated input field is selected from a grammar holding unit for holding a plurality of types of grammar, and the selected grammar is used in a speech recognition process.

An apparatus and method to successively extract a proper speech zone from speech inputted in such a fashion that noise is mixed in a speech to be recognized, and to remove noise from the detected speech zone. To this end, a noise position is estimated from an input waveform, a speech zone is detected from a speech inputted subsequently by using power information of speech at the estimated noise position, and noise is removed from the speech in the detected speech zone by using spectrum information of the speech at the estimated noise position. Further, the estimated noise zone is updated as appropriate by using a result of comparison between the power information of the input speech and the power information of the speech in the estimated noise zone so that the noise position is always properly estimated.

Method and apparatus for distinguishing speech from noise

A process for removing additive noise due to the influence of ambient circumstances in a real-time manner in order to improve the precision of speech recognition which is performed in a real-time manner includes a converting process for converting a selected speech model distribution into a representative distribution, combining a noise model with the converted to generate speech model a noise superimposed speech model, performing a first likelihood calculation to recognize an input speech by using the noise superimposed speech model, converting the noise superimposed speech model to a noise adapted distribution that retains the relationship of the selected speech model, and performing a second likelihood calculation to recognize the input speech by using the noise adapted distribution.

An apparatus, method, and storage medium for eliminating the influence of line characteristics in a real-time manner in order to raise recognition precision of input speech and to enable the speech to be recognized in a real-time manner, includes a device and step for obtaining, an estimate value of a long-time mean of a parameter from speech feature parameters which are sequentially inputted by using the speech feature parameters which have already been inputted, and a device and step for normalizing the speech feature parameter inputted at that time point by using the obtained estimate value. Each time the speech feature parameter is inputted, the latest estimate value is obtained by using the already inputted parameters including the inputted speech feature parameter, and the latest input speech feature parameter is normalized by using the updated estimate value. Since the reliability of the estimate value is higher as the number of speech feature parameters used when the estimate value is obtained is larger, the estimate value is normalized by adding a weight in accordance with the reliability.

A speech recognition method and apparatus in which a speech section is sliced by the unit of a word by spotting and candidate words are selected. Next, in a second stage, matching is conducted by the unit of a phoneme. Consequently, selection of the candidate words and slicing of the speech section can be performed concurrently. Furthermore, narrowing of the candidate words is facilitated. Furthermore, since reference phoneme patterns under a plurality of environments are prepared, recognition of an input speech under a larger number of conditions is possible using a smaller amount of data when compared with the case in which reference word patterns under a plurality of environments are prepared.
