Description

Description: TECHNICAL FIELD [0001] The present invention relates to a voice document creation device capable of efficiently creating a document by voice input. [Technical Background of the Invention and Problems Thereof] A document is created by writing on a manuscript paper exclusively using a writing instrument. On the other hand, a busy document creator can use a stenographer to create a document by dictation, or input the created document information by voice into a tape recorder or the like, and write the document by a secretary, etc. Is performed. On the other hand, recently, with the spread of Japanese word processors, documents have been easily created by a batch input method of document information by, for example, keyboard operation. However, the most natural means of inputting document information is voice input, and no cumbersome operation such as a keyboard is required.
Therefore, various attempts have been made to develop a document creation device using voice input, that is, a voice word processor. Now, research on the practical use of this type of voice word processor is being promoted with the development of information processing technology and semiconductor manufacturing technology. However, the speech recognition technology has only been put to practical use, for example, as a specific speaker recognition technology in a product management process in a factory, or as an unspecified speaker recognition technology for a limited recognition target in a telephone service or the like. In other words, the voice recognition needs to perform a recognition process in consideration of various fluctuation factors of the input voice. Therefore, in order to improve the recognition performance, various devices for the recognition processing method have been tried, and the recognition performance has been gradually improved. However, it is very difficult for human beings to achieve a 100% perfect recognition rate in a speech recognition device so that false recognition occurs in conversation. For this reason, when a document is created by voice input, strict checking of created document information is required more than when a document is created by handwriting. [Object of the Invention] The present invention has been made in view of such circumstances,
It is an object of the present invention to provide a voice document creating apparatus capable of effectively creating a document by voice input and performing an editing check of the created document easily and efficiently. [Summary of the Invention] A speech document creating apparatus according to the present invention includes a means for analyzing a speech uttered and input in a predetermined language unit, and a method for recognizing a predetermined speech processing unit by comparing the analysis result of the speech with a speech dictionary. Means for obtaining a candidate, means for comparing the sequence of recognition candidates with a language dictionary to obtain a recognition result for the input speech in the predetermined linguistic unit, first storage means for storing the recognition result, A second storage means for storing input voice data corresponding to the input voice data, and a predetermined language processing of the recognition result stored in the first storage means and the input voice data stored in the second storage means. Correspondence management means for managing in association with each other, display means for displaying the recognition result stored in the first storage means, and input speech among the recognition results displayed by the display means. Voice output instructing means for instructing a desired part in a predetermined language processing unit, and the second
Means for selectively reading out the input voice data stored in the storage means and outputting the voice. [Effects of the Invention] Thus, according to the present invention, according to the recognition result, it is possible to play back the input voice that has obtained the recognition result, and monitor and check the recognition result. It is possible to easily and efficiently perform the check processing of the document information thus corrected and the correction processing thereof. Moreover, since the input voice is stored in correspondence with the recognition result and can be reproduced as appropriate, it is possible to collectively create a document by voice input, thereby improving the document creation efficiency. Thus, a great effect can be obtained in practical use. [Embodiment of the Invention] An embodiment of the invention will be described below with reference to the drawings. FIG. 1 is a schematic configuration diagram of the apparatus according to the embodiment. Reference numeral 1 denotes an audio input unit including a microphone, an amplifier, and the like. The voice information input from the voice input unit 1 is detected by the voice detection unit 2 in a voice section. The control unit 3 controls the execution of a speech recognition process described below in accordance with the speech section detection information. When a speech to be recognized is input from the speech input unit 1, the speech analysis unit 4 including a group of band-pass filters of a plurality of channels detects the spectral components of the input speech and performs other processing on the characteristic parameters of the input speech. Seeking. The speech recognition unit 5 detects the feature vector from the time series of the feature parameters, compares the feature vector with the speech dictionary 6, calculates the similarity for each recognition target category, and the like, and converts the input speech. Recognition processing is in progress. The language processing unit 7 verifies the sequence of the recognition results of the input speech obtained in this manner linguistically with reference to the language dictionary 8 and, for example, recognizes a recognition result sequence linguistically established from a combination of a plurality of recognition candidates. Is obtained as created document information indicated by the input voice. The recognition results thus recognized are sequentially stored in the document file 10 under the management of the file management unit 9. On the other hand, when the recognition result for the input voice is stored in the document file 10, the input voice that obtained the recognition result or the voice data obtained by analyzing the input voice is stored in the voice file 11 corresponding to the recognition result. Is stored in The audio file 11 is for digitizing and storing input audio data, for example, and selectively reading out the stored audio data for reproduction and output. Then, when the speech to be used for document creation is input collectively and the recognition process for the input speech is completed, the recognition result (the creation result) stored in the document file 10 is displayed on the display unit 12 which forms an interactive interface with the operator. Document information), and the check is performed. Here, when the user wants to refer to the input speech obtained from the recognition result with respect to the displayed recognition result, the user specifies the recognition result to refer to the input speech from the speech output instructing unit 13 and the input speech. Is given. This instruction information is provided to the control unit 3 and also to the audio file 11. As a result, the file management unit 9
Under the control described above, input voice data corresponding to the specified recognition result is read out from the voice file 11 to the voice output unit 14, and the input voice is reproduced and output. Based on the reproduced voice, the operator determines whether the recognition result is acceptable or not and appropriately corrects the result. The correction of the recognition result is performed, for example, by inputting the correct recognition category using a keyboard, and the input data corrects the corresponding recognition result stored in the document file 11. If the document information (recognition result) stored in the document file 10 needs to be edited in accordance with the voice output from the voice output unit 14, the edit information is sent to the edit information input unit.
Entered from 15. Under the control of the file management unit 9 according to the input editing information, the document file 10
The document information stored in the file is edited. In this case, along with the editing operation of the recognition result stored in the document file 10, the audio data stored in the audio file 11 is also edited according to the recognition result. By the way, in the present apparatus, the recognition result stored in the document file 10 is read out to the rule synthesizing unit 16 as necessary, and the recognition result is subjected to rule synthesizing processing to obtain its speech data. . Then, the voice data that has been rule-synthesized can be output as voice via the voice output unit 17. This function is used when checking the result of recognition processing by voice.
The sequence of recognition results stored in is sequentially synthesized and output in units of language processing. In this case, when the control unit 3 is instructed to refer to the input speech for which the recognition result has been obtained with respect to the recognition result that has been rule-synthesized and output as speech, the control unit 3 terminates the speech output by the rule synthesis of the recognition result. Then, the reproduction of the cut-off sound from the input sound data several units before the language processing unit is started. That is, a document file is controlled under the control of the file management unit 9.
The recognition result from the document file 10 is read out for each predetermined language unit, and when the reference to the input voice is instructed at the time of performing the rule synthesis and outputting the voice, the reading of the recognition result from the document file 10 is performed instead. Then, the reading of the input voice data from the voice file 11 is started. The reading of the voice data from the voice file 11 is performed from the language processing unit several units before the language processing unit when the stop of the reading of the recognition result is instructed. As a result, after obtaining the voice output of the recognition result, the operator can repeat the input voice having obtained the recognition result, whereby the matching is performed. As described above, according to the present apparatus, the input voice is recognized and processed.
When the recognition results are sequentially stored in the document file 10, the input voice data obtained at the
Since these are stored in the memory 11 and managed in correspondence with each other in a predetermined language processing unit, it is possible to easily refer to the input speech obtained from the recognition result when checking the recognition result. In addition, it is possible to arbitrarily refer to the input voice in a predetermined language processing unit. Therefore, it is possible to easily and effectively check the recognition result by inputting voice data to be used for document creation at once and causing the recognition process to be performed, and then appropriately referring to the input voice. Therefore, not only the voice utterer can check the recognition result by himself, but also a third party such as a secretary can check the created document. Can be done. It is needless to say that, when storing the analyzed input voice data in the voice file 11, a process of resynthesizing the input voice according to the analyzed voice data is required. The recognition processing method of the input voice, the storage form of the input voice data, and the like may be determined according to the specifications of the device. In short, the present invention can be variously modified and implemented without departing from the gist thereof.
