Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the mobile terminal and the text generation method for the disabled of the present invention.

As shown in FIG. 1, the mobile communication terminal for the disabled of the present invention is characterized by being largely composed of a display unit 100, a controller 200, a memory unit 300, and a voice input unit 400.

The term "disabled person" refers to a user who does not have easy vocalization and keypad touch, including a brain lesion disorder. The present invention allows the disabled to speak a representative word that is easy to speak without requiring a keypad touch. The text message is generated.

Herein, the term “representative” defines words that are easily recognized by the voice input unit 400 by the speech of the disabled for each elementary, middle, and final voice, which is easy for the applicant to speak through the experiment. The word group is collected and matched to the group of words corresponding to each elementary, middle, and finality. A plurality of "keywords" are stored for each elementary, middle and finality, and each second is automatically or selected by the user. This is the word that matches the middle, final, or final word.

The display unit 100 is composed of a keypad display unit 110, a character display unit 120, a command display unit 130, a representative word display unit 140, the keypad, characters, commands, representative words under the control of the controller 200 Corresponds to the configuration for displaying such.

The controller 200 includes a character processor 210, a command processor 220, and a representative word processor 230. When the representative word is input from the voice input unit 400, the corresponding character and command from the memory unit 300, respectively. , A representative word is searched and output to the display unit 100.

The memory unit 300 includes a character memory unit 310, a command memory unit 320, and a representative word memory unit 330 to correspond to a configuration for storing data regarding a character, a command, and a representative word, respectively.

The voice input unit 400 corresponds to a configuration of recognizing a voice for a representative word and transmitting a corresponding signal to the controller 200.

First, as shown in FIG. 3A, the keypad display unit 110 includes a initial display unit, a neutral display unit, and a vertical display unit. Meanwhile, although not shown in the drawings, a number display unit and a symbol display unit may also be included. In the following description, the initial display unit, the neutral display unit, and the final display unit will be described.

In particular, in the keypad display unit 110, representative words corresponding to the respective primary, middle, and final keys of the initial display unit 111, the neutral display unit 112, and the final display unit 113 are displayed. That is, the user recognizes and speaks a representative word corresponding to each second, middle, and final key by the keypad display unit 110 so that the second, middle, and final characters corresponding to the representative word are displayed on the character display unit 120. . Of course, the keypad display unit 110 is configured so that a signal is also input by a touch, but as mentioned above, since the present invention is for the handicapped and the keypad is not easily touched, the initial display unit 111 unlike the existing keypad arrangement. , The neutral display unit 112, the vertical display unit 113 is configured to be converted by automatic or manual.

When the representative word is voice recognized through the voice input unit 400, the text processing unit 210 searches for seconds, middle, and final matches that match the representative word input from the text data previously stored in the text memory unit 310, and retrieves the found seconds. Among them, the finality is to be displayed on the character display unit 120. Meanwhile, as shown in FIG. 5, when the representative word input from the voice input unit 400 is not recognized, the character processing unit 210 may display a guide on recurrence of the representative word on the character display unit 120.

Based on such a configuration, the present invention allows the text message to be generated by the representative word recognition as shown in FIGS. 3A to 3K. Figures 3A-3K illustrate a flow for completing a text message of "a cold winter day with snow" using the present invention.

Referring to FIG. 3A, the initial display unit 111 of the keypad display unit 110 is automatically displayed at the bottom of the character display unit 120. In response, the user utters a representative word "Seoul" corresponding to the first consonant "b". When the voice of the representative word is input to the text processing unit 210 through the voice input unit 400, the text processing unit 210 matches “b” from the text memory unit 310 with the representative word by the text display unit ( 120). Hereinafter, since the operations of the voice input unit 400, the text processing unit 210, the text memory unit 310, and the text display unit 120 are the same, description thereof will be omitted.

Then, the neutral display unit 112 is automatically converted, and the user utters "Hangang" as a representative word corresponding to the neutral "TT", and when the utterance is recognized, "TT" is displayed as neutral in the character display unit.

Next, the seed display unit 113 is automatically converted, and the user utters a "carp" as a representative word corresponding to the seed "b", and this utterance is recognized, and the letter "b" is displayed on the character display unit.

Next, as shown in FIG. 3B, the initial words "o" and the neutral "ㅗ" of the second syllable are recognized and displayed by the representative words in the same manner as the flow described above. Subsequently, the terminal display unit 113 is automatically converted, and when the user utters the representative word "koi" corresponding to "n", "b" is recognized as the terminal star, and the character display unit 120 displays "eye on". .

Subsequently, as shown in FIG. 3C, when the initial display unit 111 is automatically converted and the voice is skipped, the user is switched to the neutral display unit 112, where the skip is the representative word for the function key. . Accordingly, when the user utters "grape" as a representative word for "-" corresponding to the neutral of the third syllable, "B" recognized as a final star is automatically converted into a first consonant and "snowy" is displayed in the character display unit 120. Is displayed, the keypad display unit 110 is automatically converted to the final display unit 113, and when the user utters "carp" as a representative word for "b" corresponding to the final syllable of the third syllable, the character display unit 120 displays " Snowy "is displayed and the third syllable is completed.

Next, as shown in FIG. 3D, when the user utters the "crosswalk" corresponding to the representative word of the "offset" function key, the cursor of the character display unit 120 is moved to enable the spacing. In this way, by uttering a representative word of each elementary, middle, final and function keys, the user eventually completes a text message of "a cold winter day with snow".

The command processor 220 corresponds to a configuration in which the command memory unit 320 searches for a command corresponding to a syllable, a word, or a phrase output on the character display unit 120 and displays the command in the command display unit 130. . That is, the user searches for the command corresponding to the syllables, words, and phrases displayed on the character display unit 120 by the voice of the representative word, and displays the searched command list on the command display unit 130. When a command is selected through a touch of 130, the command corresponds to a configuration that replaces the command with syllables, words, and phrases in the character display unit 120. In addition, the command processor 220 transmits the text message input by the user through the representative word to the command memory unit 320 to be stored in the command memory unit 320. During transmission, the text message is divided into words and phrases, and then transferred to the command memory unit 320, and the divided data is stored in the command memory unit 320. Therefore, the command memory unit 320 is to save the words, phrases, sentences frequently used by the user to improve the ease and accuracy in the future writing the text message. Of course, the command stored in the command memory unit 320 may be data downloaded from the service provider.

An operation relationship between the command processor 220, the command memory 320, and the command display 130 will be described with reference to FIGS. 4A to 4D. 4A to 4D illustrate a case where a user wants to generate a text message "let's make a snowman".

First, as shown in FIG. 4A, the user utters the primary and neutral voices of the first syllable, respectively, so that "nu" is displayed on the character display unit 120. When the "nu" is displayed on the character display unit 120 as described above, the command processing unit 220 automatically searches for a command including "nu" from the command memory unit 320 and displays a command list on the command display unit 130. do. The command list displayed in this way is sorted on the command display unit 130 according to a frequency used by a user or a previously stored rank. If there is no corresponding word or phrase in the displayed command, it is automatically converted to the final display unit 113 after a certain time. When the user utters a "carp" corresponding to the final syllable "b", the character display unit 120 is displayed. "Eye" is displayed. The command processing unit 220 automatically searches for a command including "eye" from the command memory unit 320 and displays a command list on the command display unit 130. Accordingly, when the user selects "snowman" as shown in FIG. 4B in the command list, the command processor 220 replaces "eye" of the character display unit 120 with "snowman" which is the selected command. In this case as well, although not shown in the drawing, in the selection of the command list, the command may be configured to match the representative word to each command list so that the command may be selected by the voice of the representative word. By repeating this flow, the user can easily complete the text message by the command list.

On the other hand, the representative word processing unit 230 searches for a representative word for the elementary, middle, and final selected by the user from the representative word memory 330 in which the representative word list for the elementary, middle, and finality is stored, and the representative word display unit 140 Corresponds to the configuration that displays a list of searched representative words. In addition, the representative word processing unit 230 recognizes the user's utterance of each representative word from the representative word list displayed on the representative word display unit 140 from the voice input unit 400 to represent a high speech recognition rate among the representative word list. The representative word display unit 140 is displayed in the order of the representative words or the representative words. In addition, when the main word display unit 140 is displayed in the order of the representative words or the representative words with the high voice recognition rate, the user selects the representative word matching the corresponding elementary, middle, and finality, and the representative word processing unit 230 The keypad display unit 110 is converted to the representative word selected for the corresponding seconds, middle, and finality.

An operation relationship between the representative word processing unit 230, the representative word memory unit 330, and the representative word display unit 140 will be described with reference to FIGS. 6A to 6D.

First, as shown in FIG. 6A, when the user selects an environment setting (representative word change) on the terminal interface, selection keys 141, 142, and 143 and an automatic setting key are displayed on the representative word display unit 140. 144, the advanced setting key 145 is displayed. When the user selects the corresponding first key 141, the representative word processing unit 230 searches for the representative word matching the corresponding first word from the representative memory unit 333 and displays the representative word list on the representative display unit 140. Sort it. In this case, it is reasonable that the speech recognition rate is sorted in order of the representative words according to the preset. Accordingly, when the user selects the automatic setting key 144, the representative word is automatically activated according to the sorting order among the representative words matching the initial consonant. Next, as shown in FIGS. 6B and 6C, the user speaks with respect to the activated representative word, and for each of these utterances, the representative word processor 230 has the highest voice recognition rate among the spoken representative words. The word is displayed on the representative word display unit 140 and presented. Accordingly, when the user selects a representative word having a high voice recognition rate presented in the representative word display unit 140, as shown in FIG. 6D, the representative word is automatically converted into the initial consonant in the keypad display unit 110. As a result, the user can assign a representative word having a high voice recognition rate according to his / her voice to each elementary, middle, and final voice, thereby reducing the number of errors and retries due to the voice recognition rate drop in the text message writing. It will be possible.

On the other hand, the character generation method for the disabled according to the present invention, as shown in Figure 2a representative voice input step (S10); Searching for a second, middle, and finality corresponding to the representative word (S20); It has a step (S30) to display the seconds, middle, and finality corresponding to the representative word. That is, by repeating the steps (S10, 20, 30) is a text message to be generated is completed.

Here, in the step S20 of searching for a primary, middle, and final word corresponding to the representative word, when searching for the primary, middle, and final word corresponding to the representative word, the syllables, words, and phrases completed by the corresponding primary, middle, and final word A step S21 of searching for a command is included. When the command is searched, the next step is to display a list of commands corresponding to the syllables, words, and phrases formed by the displayed seconds, middle, and final words in S30. It is to include (S31). Thereby, the user does not need to complete the corresponding elementary, middle, and finality of the text message that he or she wants to write by the utterance of the representative word, and replaces the commands corresponding to the syllables, words, and phrases that are used frequently or frequently This makes texting easier.

In addition, the representative voice input step (S30) may be a step that can be selected or converted to the representative word for the corresponding elementary, middle, and final. That is, the user changes the representative words for the corresponding elementary, middle, and final words when an error occurs due to low vocalization of the matched representative word or low voice recognition rate by the representative word. To this end, as shown in FIG. 2B, first, a step S31 of selecting the finality is made. Thereafter, a step (S32) of searching for a representative word for the selected super, middle, and final species is provided. Thereafter, there is a step S32 of displaying the searched representative word list for the selected second, middle, and final species. Next, a voice input step S33 is provided for each representative word with respect to the representative word list displayed next. When the voice for the representative word is input in this way, the representative word list has a step of determining and displaying a representative word having a high voice recognition rate (S34). As mentioned above, determining and presenting a representative word having a high voice recognition rate among the representative word list is performed by the representative word processing unit 230. Finally, when the user selects the suggested representative word, the representative word for the corresponding elementary, middle, and final words is converted into the representative word with the high voice recognition rate of the user.

Although described and described in connection with the preferred embodiment of the present invention, it should be understood that the present invention may be variously modified and changed without departing from the spirit or the scope of the present invention provided by the claims below.
