TECHNICAL FIELD OF THE INVENTION
The present invention relates to a portable information terminal device having a character string kanji conversion function.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, portable information terminal devices such as PDAs (Personal Digital Assistants) have been required to simplify operation input and increase efficiency. For example, a portable information terminal device capable of performing operation input by various methods such as keyboard, pen touch, and handwritten character recognition using a pen has been devised. In addition, with recent technological advances, data input by voice recognition is being put to practical use.
[0003]
In a device for inputting data by voice recognition, voice data input via a microphone is converted into reading characters with reference to a voice dictionary, and the reading characters are further converted into characters mixed with kanji and kana using a dictionary. In this way, the user simply inputs voice from the microphone, and the voice data is automatically converted to kanji, so that operation input can be performed easily.
[0004]
[Problems to be solved by the invention]
However, compared to a general computer, the conventional portable information terminal device has limited functions to be mounted due to miniaturization, so that the processing capacity of the CPU is low and the memory capacity is limited. In addition, since the portable information terminal device is used in a portable manner, has a very wide use environment and is required to execute various processes, it is impossible to reduce other functions by emphasizing only the voice recognition function. Therefore, in the conventional portable information terminal device, for example, when inputting an address book or a schedule by voice data, erroneous input due to a recognition process or a conversion process is not small.
[0005]
In addition, since the recognition process of voice data and the kanji conversion process of recognized data impose a burden on a CPU and a memory, a conventional portable information terminal device requires a lot of time to perform an input process using voice data. There was also room for improvement.
[0006]
On the other hand, in order to improve the accuracy of voice data input, a method of performing a voice recognition process after setting a data input range, instead of simply performing a data input using only a voice recognition engine, has been devised. However, according to this method, it is necessary to set the input range every time voice data is input, and the operation is complicated and inefficient.
[0007]
An object of the present invention is to improve the accuracy of data input in a portable information terminal device, and to realize simplification and efficiency of data input.
[0008]

[0014]
The connection base 3 includes an interface (not shown) for connecting to each of the portable information terminal device 1 and the PC 2, and mediates the exchange of data between these devices. Specifically, it adjusts the data transfer speed.
[0015]
FIG. 2 is a block diagram showing a schematic configuration of portable information terminal device 1 according to the present embodiment. As shown in FIG. 2, the portable information terminal device 1 includes a CPU 11, a display unit 12, a touch panel 13, a key input unit 14, a RAM 15, a storage device 16, a voice input unit 17, a voice recognition unit 18, a PC connection communication unit 19, The communication control unit 20 includes a communication control unit 20. The units are connected to each other by a bus 21 so that data can be transmitted and received between the units.
[0016]
Here, various dictionaries and data stored in the portable information terminal device 1 and the PC 2 will be described with reference to FIG. FIG. 3A is a diagram illustrating dictionaries and data stored in the portable information terminal device 1 and the PC 2, and FIG. 3B is a diagram illustrating an example of the content of personal information data.
[0017]
As shown in FIG. 3A, the storage device 16 of the portable information terminal device 1 stores various dictionaries such as a command word dictionary 1a, a general dictionary 1b, and an item dictionary 1c, "schedule", "TO DO", and "TO DO". Personal information data including "address book" is stored, and temporary registration data and unregistered data described later are stored in the RAM 15. The PC 2 stores a reading conversion dictionary 2a and a kanji dictionary 2b.
[0018]
The command word dictionary 1 a stored in the storage device 16 is a dictionary of commands (command words) for starting processing executable by the portable information terminal 1, and the CPU 11 is input via the voice input unit 17. The voice data is converted into text data by the voice recognition unit 18, and if the text data includes a character string matching the command registered in the command dictionary 1a, it is recognized as a command, and the commanded process is executed. I do.
[0019]
The general dictionary 1b is a kanji conversion dictionary that stores kana reading data and kanji data in association with each other. Note that the kanji data referred to in the present embodiment includes not only data composed only of kanji but also data in which kanji and kana are mixed.
[0020]

[0021]
As shown in FIG. 3B, the item dictionary 1c has items such as a name (reading as kanji), a telephone, an address, and an e-mail address. It is stored in association with kanji data. Further, in the item of the schedule content, the reading data of the word related to the schedule content and the kanji data are stored in association with each other, and as shown in FIG. When the voice data is input, the CPU 11 searches the item dictionary 1c for the reading data "Kikakukaigi" using only the words classified into the item "Schedule contents" as a search range, and reads the kanji data " The kanji conversion is performed by reading the "plan meeting" from the item dictionary 1c.
[0022]
As described above, since the search range can be limited by designating items using the item dictionary 1c, the conversion accuracy from reading data to kanji data is improved. Also, the time required for conversion is reduced.
[0023]
The temporary registration data stored in the RAM 15 matches reading data of personal information data and reading data registered in the item dictionary 1c among text data generated from voice data in a voice data input process described later. The CPU 11 temporarily stores the temporarily registered data in the RAM 15 because it is text data of a kana that cannot be converted to kanji data because it does not include a character string. The temporary registration data is converted into kanji data using the kanji dictionary 2b by the PC 2 synchronized with the portable information terminal device 1 and registered in the item dictionary 1c in association with the kanji data in a synchronous registration process described later.
[0024]
The unregistered data stored in the RAM 15 coincides with the personal information data in the storage device 16 among the text data input from the key input unit 14 in the key input data registration processing (described later) executed by the CPU 11. The data does not include a character string, is not registered in the item dictionary 1c, and is registered in the general dictionary 1b, and the CPU 11 temporarily stores unregistered data in the RAM 15. When the unregistered data is converted into kanji data using the reading conversion dictionary 2a by the PC 2 synchronized with the portable information terminal device 1 in a synchronous registration process described later, the unregistered data is registered in the item dictionary 1c in association with the kanji data. You.
[0025]
The reading conversion dictionary 2a shown in FIG. 3A is a dictionary for converting unregistered data stored in the PC 2 into kanji. When unregistered data is input from the portable information terminal device 1 in synchronization with the portable information terminal device 1, the PC 2 converts the unregistered data into kanji data using the reading conversion dictionary 2a and outputs the kanji data to the portable information terminal device 1.
[0026]
The kanji dictionary 2b is a dictionary for converting tentatively registered data stored in the PC 2 into kanji. When the temporary registration data is input from the portable information communication terminal device 1, the PC 2 converts the temporarily registered data into kanji data using the kanji dictionary 2b and outputs the kanji data to the portable information terminal device 1.

[0063]
Here, a specific example of the audio data input processing will be described with reference to FIG. As shown in FIG. 8, in the voice data input process, when the voice data “Kenmei Hanba Kaigi” is input from the voice input unit 17, the voice data is converted into text data by the voice recognition unit 18. Convert. Next, the CPU 11 searches the reading data associated with “Kenmei” of the personal information data stored in the storage device 16 for “Hankai Igi” and finds the corresponding reading data. The kanji data “sales conference” corresponding to the read data is read out and displayed on the display unit 12.
[0064]
On the other hand, when the CPU 11 determines that the reading data “Hankai Kaigi” corresponding to the item “Kenmei” is not registered in the personal information data, the reading data classified into the “Kenmei” item in the item dictionary 1c is determined. From among them, the reading data “Hankai Kaigi” is searched, and the kanji data “Sales Conference” corresponding to the searched reading data is read from the item dictionary 1 c and displayed on the display unit 12.
[0065]
As described above, the CPU 11 of the mobile communication terminal device 1 converts the voice data into text data in the voice data input processing, converts the text data based on the item, and stores the text data in the RAM 15 as temporary registration data when the conversion is not possible. Then, in the dictionary change processing, the dictionary to be used is changed and the tentative registration data is converted into kanji. In the key input data registration process, text data not registered in the item dictionary 1c is stored in the RAM 15 as unregistered data. In the synchronous registration process, the temporary registration data and the unregistered data are output to the PC 2, kanji data is obtained from the PC 2, and registered in the item dictionary 1c.
[0066]
Therefore, by using the item dictionary 1c that classifies and stores the words for each item, the speech recognition rate can be improved, and the input processing of the speech data and the key input data can be quickly executed by a simple operation. In addition, since the input data can be converted into kanji by synchronizing with the PC 2, it is not necessary to mount a dictionary having an enormous data amount on the portable information terminal device 1, and this does not hinder miniaturization.
[0067]
In the synchronous registration process, the CPU 11 registers the data input by the user and the corresponding kanji data in the item dictionary 1c, so that the data can be easily and quickly converted to the desired kanji in the second and subsequent data inputs. It is highly convenient.
[0068]
Note that the present invention is not limited to the above embodiment. For example, when text data input by the user is converted to kanji or kana and displayed on the display unit 12, for example, when there are a plurality of kanji data corresponding to one reading data, a plurality of conversion candidates are displayed. If there is, all conversion candidates may be displayed and converted to kanji data according to the selection by the user.
[0069]
Further, the simplified reading data may be registered in the item dictionary 1c in association with the kanji data. For example, by registering a nickname of a name in association with a full name, key input and voice input can be performed more easily and quickly.
[0070]
In addition, the detailed configuration and detailed operation of each terminal or constituent parts constituting the mobile communication terminal device 1 can be appropriately changed without departing from the spirit of the present invention.
[0071]
【The invention's effect】
According to the first aspect of the present invention, the accuracy of data input in the portable information terminal device can be improved, and the simplification and efficiency of data input can be realized.
