2. Description of the Related Art Today, there is known a voice input type Japanese input system as shown in FIG. 9 for inputting a character string into a computer. In the speech conversion dictionary, a feature amount of speech data and a notation character string corresponding to the feature amount are registered in advance as a table. Microphone 61
When the voice is input from the voice conversion unit 63, the voice conversion unit 63 extracts a predetermined feature amount from the input voice, calculates a matching with the feature amount of each written character string registered in the voice conversion dictionary 65, The one with the highest degree of matching is output as the notation character string. Since Japanese input can be performed by voice input, even an operator who is not used to keyboard input can input Japanese.

However, the above-mentioned voice input system has the following problems. To change the converted notation character string after the conversion once, it was necessary to perform voice input again. In some cases, the operator may want to change the notation method. For example, kanji is written in hiragana, and uppercase letters are written in lowercase letters.
In such a case, in order to be able to freely select the notation method, it is conceivable that the notation method is listed in the candidate list and can be selected, but each time, a dialog for selecting the candidate list is displayed on the screen. It is complicated.

[0004] The present invention solves the above problem and provides a notation character string conversion device or method capable of easily converting notation of Japanese input.

BEST MODE FOR CARRYING OUT THE INVENTION Description of Functional Block Diagram One embodiment of the present invention will be described with reference to the drawings. FIG.
2 shows a functional block diagram of the notation character string conversion device 10.
The notation character string conversion device 10 converts a notation character string given from a sound data conversion unit that extracts a feature amount from audio data input by an operator, converts the characteristic amount into a notation character string, and outputs the character string, based on a conversion command from the operator. A notation character string storage device, a manual conversion device 13,
A language rule storage unit 17, an automatic conversion unit 15 and an output unit 14 are provided.

First, a description will be given of the voice data conversion means 5 for providing a notation character string to the notation character string conversion device 10. When the operator inputs data to the voice input unit 3, the voice conversion unit 6 extracts a predetermined feature amount from the voice data.
A plurality of conversion candidates are stored in the voice conversion dictionary 7 in advance. Each conversion candidate is composed of a feature amount, its notation character string, and its reading character string. Voice conversion means 6
Determines the degree of coincidence between the extracted feature value and the feature value of each of the conversion candidates, and outputs the notation character string and the read character string of the best matching candidate.

The written character string output from the voice data conversion means 5 is stored in an undetermined character string storage means 12 in an undetermined state, and the read character string is stored in a read character string storage means 11. The language rule storage means 17 stores a language rule. In the present embodiment, a conversion dictionary for kana-kanji conversion is adopted as a language rule. More specifically, co-occurrence information composed of a notation character string having a co-occurrence relation and a reading character string thereof is employed.

The automatic conversion means 15 determines the relation of a specific notation character string among the plurality of notation character strings stored in the unconfirmed character string storage means 12 based on the language rules of the language rule storage means 17, If it is determined that the relationship between the notation character strings does not match the language rule, the notation state of the notation character string is changed to match the language rule.

In this embodiment, the automatic conversion means 15
Performs the above determination and change in consideration of the read character string stored in the read character string storage unit 11.

The output means 18 is an undetermined character string storage means 1
The display character string stored in the display means 19 is in an undetermined state.
The display control command is output so as to be displayed in.

When a conversion instruction is given to the noted portion of the written character string stored in the undetermined character string storage means 12, the manual conversion means 13 performs conversion based on this instruction. Specifically, when the operator selects a conversion command assignment key in which the conversion commands are assigned by function, the conversion command is stored in the undetermined character string storage unit 12 based on the conversion command assigned to the selected conversion command assignment key. The undetermined character string of the noted portion is converted. This conversion instruction is, for example, an instruction to change the notation of the undetermined character string of the noted portion. Further, when given a specific command for specifying the target portion, the manual conversion unit 13 specifies the command and performs the conversion.

2. 2. Hardware Configuration (2.1) Outline FIG. 2 shows a kana-kanji conversion device 40 incorporating a voice conversion device and a display character string conversion device. The kana-kanji conversion device 40 includes an input device 41, a control device 43, a display device 45, and a storage device 47.

Audio data is input to the microphone 34.
The input audio data is digitally converted by the interface 33 and temporarily stored in a work buffer (not shown) of the memory 27.

The hard disk 26 stores a voice conversion program 26a, a voice conversion dictionary 26b, a kana-kanji conversion program 26c, a kana-kanji conversion dictionary 26d, and an application program 26p. FIG. 4 shows the data structure of the voice conversion dictionary 26b. As described above, the written character string and its read character string are stored for each voice data. The speech conversion dictionary 26b also stores inter-word connection data indicating how words are connected (not shown). FIG. 5 shows an example of the co-occurrence dictionary stored in the kana-kanji conversion dictionary 26d. Notation character strings having a co-occurrence relationship are stored in association with each other. The voice conversion program 26a and the kana-kanji conversion program 26c will be described later. The application program 26p
The notation character string is received from the kana-kanji conversion program 26c and output to the CRT 30.

The CPU 23 shown in FIG. 3 controls each section via the bus line 29 according to the two programs stored in the hard disk 26. These programs are read from the flexible disk 25a in which the programs are stored via the FDD 25 and installed on the hard disk 26. In addition to the flexible disk, a hard disk may be installed from a computer-readable storage medium in which a program such as a CD-ROM or an IC card is substantially integrated. Furthermore, you may make it download using a communication line.

In the present embodiment, the program is installed on the hard disk 26 from the flexible disk, so that the computer indirectly executes the program stored on the flexible disk. However, without being limited to this, the program stored in the flexible disk is stored in the FDD25.
Alternatively, it may be executed directly from. Note that, as a program executable by a computer, not only a program that can be directly executed by simply installing it as it is, but also a program that needs to be temporarily converted into another form (for example,
Decompression of data that has been compressed, etc.), and also includes those that can be executed in combination with other module parts.

The memory 27 has an audio data buffer 27
a, a feature buffer 27f, a post-conversion buffer 27e, a reading buffer 27b, a semi-determined buffer 27c, and a defined buffer 27d.

The audio data buffer 27a, the feature buffer 27f and the post-conversion buffer 27e are buffers for an audio conversion program. Audio data buffer 27a
Stores digital audio data obtained by digitally converting input audio data. The voice feature extracted by the voice conversion program 26a is stored in the feature buffer 27f. The post-conversion buffer 27e stores the written character string specified by the voice conversion program 26a and its read character string.

Reading buffer 27b, semi-determining buffer 27
c, the determination buffer 27d is a buffer for a kana-kanji conversion program. The reading character strings stored in the converted buffer 27e are sequentially stored in the reading buffer 27b. The semi-determined buffer 27c includes a post-conversion buffer 27e.
Are sequentially stored. The notation character string determined by the determination command given from the keyboard 28 is stored in the determination buffer 27d. The memory 27 also stores various calculation results and the like.

On the CRT 30, a notation character string in an undetermined state or a notation character string in a confirmed state is displayed. The keyboard 28 is provided with various conversion command assignment keys.

3. Next, a program stored in the hard disk 26 will be described with reference to FIGS. In this embodiment, the application program 26p is:
The voice conversion program 26a and the kana-kanji conversion program 26b are called in a state where a character string can be input, and a kana-kanji character string is input. The voice conversion program 26a specifies the notation character string (FIG. 6, step ST0 to step ST0).
3) The kana-kanji conversion program 26b
Is passed to the application program 26p in an undetermined state. The application program 26p displays the notation character string in an undetermined state.

The kana-kanji conversion program 26b converts the character string to be written based on the conversion command from the operator (FIG. 7, step ST4 to FIG. 8, step ST33). The converted notation character string is passed to the application program 26p. In the present embodiment, the kana-kanji conversion program 2
6b, "ATOK11" manufactured by Justsystem Co., Ltd., which is one of IME (input method editor)
(Trademark) and "Ichitaro 8" (trademark) made by the company was adopted as the application program 26p.

First, the application program 26p
Will be described. Application program 26p
Is a Japanese document creation program, and when activated, a character string input enabled screen is displayed on the CRT 30 (not shown).

In this state, the voice conversion program 26a is called. The following processing is executed by the voice conversion program 26a. The operator operates the microphone 34 shown in FIG.
Input audio data from. The CPU 23 includes a microphone 34
It is determined whether or not there is a voice input (step ST0 in FIG. 6).
The digital audio data digitally converted by the interface 33 is stored in a (step ST1). For example, when "Sansei-Arikari-no-Sui-Eki" is uttered, the digitally converted data is stored in the audio data buffer 27a.

The CPU 23 has an audio data buffer 27a
A feature amount is extracted from the digital audio data stored in (step ST2). Next, the voice data and the inter-word concatenation data registered in the voice conversion dictionary 26b shown in FIG. 3 are collated to obtain a character string having the highest matching degree, and stored in the converted buffer 27e (step ST3). For example, in this case, a conversion candidate is specified for each word, such as "sansei / to / arikasei / no / suoiyoueki /", and a conversion candidate is specified for each word. Agree/
And / alkaline // aqueous solution ”and the reading character string“ sansei / to / akarisei / no / suoiyoueki ”are stored.

In step ST0 in FIG. 6, if there is no voice input, the voice conversion program ends.

Next, the kana-kanji conversion program 26b is called. The following processing is executed by the kana-kanji conversion program 26b. The CPU 23 determines whether or not a new character string is stored in the post-conversion buffer 27e (step ST4 in FIG. 7). If a new character string is stored, the conversion unit (phrase) of the kana-kanji conversion program is used. ) Is corrected, and the written character string is stored in the undetermined buffer 27c and the read character string is stored in the read buffer 27b (step ST5 in FIG. 7). In the above case,
For example, the notation character string “agreement / alkaline / aqueous solution” is stored in the semi-fixed buffer 27c, and the reading “sansanto / arukasei / suoiyoeki” is stored in the reading buffer 27b.

Next, the CPU 23 executes the semi-determined buffer 2
The notation character string "agreement and alkaline aqueous solution" stored in 7c is passed to the application program 26p with the condition that it is in a semi-determined state (step ST in FIG. 7).
7). The application program 26p displays the replaced notation character string on the CRT 30 in a semi-determined state.

Next, the CPU 23 executes the semi-determined buffer 2
It is determined whether the character string stored in 7c matches the Kana-Kanji conversion rule (step ST9 in FIG. 7). In this example, the determination is made based on the co-occurrence dictionary shown in FIG. In this case, it is found that the co-occurrence relationship with the notation character string “alkaline” is not the notation character string “agree” but the notation character string “acidity”.

Therefore, the CPU 23 determines that the character string stored in the semi-fixed buffer 27c does not conform to the Kana-Kanji conversion rule, and converts the written character string stored in the semi-fixed buffer 27c based on the Kana-Kanji conversion rule. (Step ST11 in FIG. 7). Specifically, “agree” is replaced by “acid”, and “agree and alkaline aqueous solution” is stored in the semi-fixed buffer 27c.

Next, the CPU 23 executes the semi-determined buffer 2
The notation character string “acidic and alkaline aqueous solution” stored in 7c is transferred to the application program 26p in a semi-determined state (step ST13 in FIG. 7). The application program 26p displays the replaced notation character string on the CRT 30 in a semi-determined state.

If it is determined in step ST9 that the values match, the processes in steps ST11 and ST13 are not performed.

Next, CPU 23 determines whether or not there is a key operation (step ST14). If there is no key operation, the kana-kanji conversion program ends, and the voice conversion program shown in FIG. 6 is executed.

On the other hand, if there is a key operation in step ST14, the flow advances to step ST15 to determine the type of the key.

If the type of the key is the decision key, the process proceeds to step ST17 in FIG. 8, and the data of the semi-decision buffer 27c is stored in the decision buffer 27d. Then, it is passed to the application program 26p with the condition of the fixed state. The application program 26 p
The written character string “acidic and alkaline aqueous solution” stored in d is displayed on the CRT 30 in a fixed state.

If the type of key is a cancel key in step ST14, the data in the semi-fixed buffer 27c and the read buffer 27b are cleared (step ST2 in FIG. 8).
5). Then, the process ends.

If no character string is additionally stored in the post-conversion buffer 27e in step ST4 in FIG. 7, the process proceeds to step ST14 to determine whether or not a key operation has been performed.

The processing by the kana-kanji conversion program and the processing by the voice conversion program are sequentially repeated.

If the input voice has not been converted into the desired notation character string, the operator proceeds to step ST1.
In step 4, a key for performing a desired conversion may be operated. For example, if "Taiko is in the box" in Kanji, and you want to write "Taiko" in the form of a letter, the following operation may be performed. In the semi-determined state,
Operate the notice phrase change key to move the cursor to the "Taiko" part. Accordingly, the CPU 23 proceeds to step ST31 in FIG. 8 and changes the noticeable phrase. Then, if the katakana key is operated, the process proceeds from step ST14 to step ST27, where the notation character string of the noticed phrase in the semi-fixed buffer 27c is converted into katakana with reference to the reading character string in the reading buffer 27b.

As described above, the display control instruction is output so that the noticeable phrase, which is the noticeable portion, is displayed in a distinguishable manner, and the notation character string is changed based on the given notation change instruction. As a result, the written character string can be easily changed.

The same applies to other conversions. For example, if you want to convert Hiragana, you can operate the Hiragana conversion key. The CPU 23 determines that the type of the key is a hiragana key, and converts the target phrase in the semi-fixed buffer 27c into hiragana (step ST29 in FIG. 8).

If the key type is a half-width conversion key, the target phrase in the half-fixed buffer 27c is half-width converted (step ST35 in FIG. 8). Then, returning to step ST14, it is determined whether a key operation has been performed.

If the type of key is a delimiter position change key, the delimiter position of the reading buffer 27b is changed (step ST21 in FIG. 8), and the read character string whose delimiter position has been changed is passed to the application program 26p (step ST23). ). Then, returning to step ST14,
Determine whether a key operation has been performed.

As described above, in the present embodiment, the notation character string converted by the voice conversion program is received in an undetermined state by the Kana-Kanji conversion program, which is an IME, and displayed on the CRT 30 in an undetermined state. Notation strings are converted based on the operation. Therefore, more efficient character string input becomes possible. In addition, since the conversion can be performed with the same operability as the kana-kanji conversion program familiar to the operator, there is no need to learn the operation separately.

Also, in the present embodiment, the notation character string converted by the voice conversion program is checked by the kana-kanji conversion program, and if it is not an appropriate notation character string, it is re-converted based on the conversion rules of the kana-kanji conversion program. I am trying to do it. As a result, even if the speech conversion program has not been trained, appropriate Kana-Kanji conversion can be performed by utilizing the Kana-Kanji conversion rules already accumulated by the operator.

In the above embodiment, the hiragana conversion,
Katakana conversion, phrase break position change, half-width conversion, confirmation,
Although the case of an instruction such as cancellation has been described, other functions such as operation of a cursor, deletion of one sound before the cursor, movement of the cursor to the left, movement of the cursor to the right, and the like can be similarly applied.

4. Other Embodiments In the present embodiment, the case where co-occurrence information is used as the kana-kanji conversion rule has been described, but other rules, such as learning information, may be used. Also,
Not only kana-kanji conversion to Japanese but any language rules may be used. For example, the same can be applied to voice input in other languages such as English and Chinese.

When there is a homonymous object word, by using co-occurrence information as in the present embodiment, it is possible to obtain an appropriate written character string from data input by voice without an operation by an operator. On the other hand, reading voice data (technical terms and the like) not registered in the voice conversion dictionary of the voice conversion program cannot be correctly converted.
The reason is that the voice conversion program converts the speech into a written character string having a pronunciation very similar to the pronunciation.
For example, if there is no term for a patent, it is converted to a similar Tokyo, etc., and its reading is also converted to “Tokyo”. In general, a kana-kanji conversion program searches for a conversion candidate by referring to a written character string or a reading given from a voice conversion program. Therefore, even in such a case, a written character string having a similar reading may be stored as a kana-kanji conversion rule in the kana-kanji conversion program so that conversion can be performed accurately. in this way,
By storing the similar word reading data and predicting the correct reading, an appropriate written character string can be obtained even if a slightly shifted reading is given from the speech conversion program.

Also, words that are in Japanese English,
For example, as for “system” and the like, the spelling “system” may be stored as a notation character string and converted to this.

In the present embodiment, the voice conversion program is a program manufactured by IBM Japan, Ltd.
Although iaVoice (trademark) was adopted, the present invention is not limited to this, and other voice recognition programs can be similarly applied. In this way, when a commercially available voice conversion program is used as a voice input engine, even if the conversion rate is not so good due to the conversion target field, the conversion rules of the kana-kanji conversion stored by the operator are used. Thus, a desired written character string can be obtained.

Although the speech conversion program has been described as being realized by software, it may be realized by hardware. That is, the audio data conversion means is a concept including the audio data conversion device.

In the present embodiment, the application program 26p is provided with a condition that it is in a semi-determined state, and is displayed on the CRT 30 in a semi-determined state to the application program 26p. That is, the kana-kanji conversion program outputs the display control command so that the notation character string stored in the undetermined buffer is displayed in an undetermined state. However, as for the display in the undetermined state, not only is the application program 26p executed in this way, but the Kana-Kanji conversion program receives a reply command indicating that no display was made from the application program 26p, and displays it. You may. In addition, such display may be realized by sharing with the operating system (OS).

In the present embodiment, the functions shown in FIG. 1 are realized by using the CPU 23 and software. However, some or all of them may be realized by hardware such as a logic circuit.
