Other objects, specific advantages and novel features of the present invention will become more apparent from the following detailed description and the preferred embodiments associated with the accompanying drawings.

Hereinafter, with reference to the accompanying drawings to describe the embodiment of the present invention in detail.

1 is a block diagram showing the internal configuration of a portable terminal having a key input voice transmission function according to the present invention. As shown in FIG. 1, a portable terminal having a key input voice transmission function according to the present invention includes a key input unit 10, a display unit 20, a microphone 30, a power supply unit 40, a control unit 50, and a storage unit. The unit 60 includes a voice processing unit 70, a voice output unit 80, and a wireless transmission / reception unit 90.

The configuration of the display unit 20, the wireless transmission and reception unit 90 and the power supply unit 40 is the same as that of the conventional portable terminal, and the description thereof will be omitted since it is not directly related to the present invention.

The key input unit 10 is a portion in which the input unit 70 inputs various operation command signals for operating the portable terminal. The keypad is used a lot, but input devices such as a touch screen, a track pad, a track point, and a stylus are used. It may be.

The microphone 30 is an electronic device that converts sound energy into electrical energy, and has a function of receiving a user's voice as voice data for a shortcut key in addition to a normal function of receiving a user's voice during a call. The microphone 30 includes a diaphragm (not shown), a converter (not shown), an output unit (not shown), and includes a carbon microphone, a crystal microphone, a dynamic microphone, a condenser microphone, and the like.

The storage unit 60 stores a voice extraction module for extracting number data related to a telephone number, character string data related to a shortcut key, voice data related to number data and phonemes, and voice data corresponding to a key input through a key input unit. . The string data will be described in detail with reference to FIG. 2.

The voice data refers to a code for voice frequency characteristic information of each character corresponding to the number data and a code for voice frequency characteristic information of all phonemes in Korean.

As the storage unit 90, a nonvolatile memory for storing various programs, character string data, voice data, and a voice extraction module and a volatile memory for loading a program when the program and the flash control module are executed are used. As nonvolatile memory, a flash memory that is nonvolatile and capable of reading and writing memory is mainly used to change a character string corresponding to a shortcut key.

The voice processing unit 70 converts the voice data into an analog voice signal or converts the analog voice signal input through the microphone 30 into digital voice data.

The voice output unit 80 converts the analog voice signal converted by the voice processor into voice and outputs the voice. Generally, a speaker is used. A speaker is an acoustic device that converts an electrical signal into vibration of a diaphragm to generate a small density wave in the air to radiate sound waves. There are a dynamic type and a condenser type according to its operation principle.

2 is a diagram conceptually illustrating a storage structure of character string data stored in a storage unit. As shown in FIG. 2, there are two types of character string data stored in the storage unit, name data and character string data corresponding to shortcut keys.

The number data is a character corresponding to the numbers 0 to 9 and is actually stored as an ASCII code for the character.

The character string data corresponding to the shortcut key stores the name or name of the corresponding object with respect to the shortcut key for which the user frequently designates the phone number of the call, and is stored in ASCII code like the number data.

In FIG. 2, a "-" symbol beside a number means a shortcut key. That is, "1-" means to press and hold 1 in the key input unit 10.

3 is a flowchart illustrating a voice transmission process according to a key input according to the first embodiment of the present invention. The processes of FIG. 3 are performed by the controller 50 executing the voice extraction module stored in the storage 60.

First, a dial key is input through the key input unit 10 (S100). That is, the user inputs a number by pressing a number in the key input unit.

The controller 50 checks whether the input dial key is a number, and if it is a number, calculates the time when the dial key is pressed. If the pressed time is longer than the set time, it is determined that the shortcut key is input and voice data corresponding to the shortcut key is extracted (S110). For example, if No. 1 is pressed for a set time or more, it is determined that the No. 1 hotkey is pressed, and the string code for the string “Kang Suk-Hee” (see FIG. 2) for the hotkey No. 1 is extracted from the storage unit 60. , Voice data corresponding to each phoneme "strong", "stone", "hee" is extracted from the storage unit 60 and transmitted to the voice processing unit 70.

If the time when the dial key is pressed is less than the set time, the dial key input until the call key is pressed is stored in the storage unit 60, and enters the standby mode for receiving the next dial key (S120). That is, to store the stored phone number until all the phone numbers are entered. For example, if " 0, 1, 1, 1, 2, 3, 4, 5, 6, 7 " is continuously input without input of a call key, the series is temporarily stored in the storage unit 60. .

If the call key is pressed, voice data corresponding to a series of dial keys is extracted from the storage unit 60 (S130). For example, when a call key is input after a series of dial keys of "0, 1, 1, 1, 2, 3, 4, 5, 6, 7" is input, the controller 50 stores the storage unit 50. After extracting the text data corresponding to each numeric data of the series of dial keys from the storage unit 60, the voice data corresponding to each character data is extracted from the storage unit 60 and transmitted to the voice processing unit 70.

Next, the voice processing unit 70 processes the transmitted voice data (S140). When the input dial key is a shortcut key, the voice processor 70 processes each phoneme data into a voice signal, and then converts the phoneme data into an analog signal. When the input dial key is a phone number, the voice processor 70 converts the voice data into an analog signal.

Finally, the converted voice analog signal is output as a voice signal through the voice output unit 80 (S150).

FIG. 4 is a detailed flowchart illustrating a process of processing a voice data signal when the dial key input in FIG. 3 is a shortcut key. 4 are performed by the controller 50 executing the voice extraction module stored in the storage unit 60 as in FIG. 3.

First, character string data corresponding to the dial key is extracted (S200). When the shortcut key "1" is pressed by the dial key as described above, the controller 50 extracts the corresponding character string data "Kang Suk-hee" from the storage unit 60.

Next, the code value for the phoneme of the string is extracted (S210). That is, the controller 50 extracts ASCII code values for the phonemes " strong ", " stone " and " hee " of the character string from the storage unit 60. FIG.

Next, voice data for the phoneme is extracted (S220). That is, the controller 50 extracts the voice data having the frequency characteristic information corresponding to each phoneme "strong", "stone", "hee" from the storage unit 60.

Next, the controller 50 generates a voice signal for the phoneme by using the extracted voice data (S230).

Next, the controller 50 synthesizes a voice signal for the generated phonemes (S240). For example, the audio signal of the phoneme for each phoneme "strong", "stone", "hee" is synthesized.

Next, the voice signal synthesized by the voice processor 70 is converted into an analog signal (S250) and output through the voice output unit 80 (S260).

5 is a flowchart illustrating a process of inputting a voice signal through the microphone 30 according to the second embodiment of the present invention, converting the voice signal into voice data, and storing the same. FIG. 5 does not require a synthesis step of a voice signal in a voice transmission process for key input by storing voice data for a dialing input key in advance in the storage unit 60 through the microphone 30.

First, a voice data storage function selection is input (S300). That is, the user selects a voice data storage function from the screen menu of the portable terminal.

Next, the type of voice data to be stored is selected (S310). When the voice data storage function selection is input in step S300, a screen for selecting the voice data to be stored is displayed on the screen of the portable terminal. The user selects either a number key or a shortcut string on the screen.

Then, a voice signal is input through the microphone 30 (S320). If the user selects a shortcut key string, the user inputs a shortcut key to be designated by the user, and then inputs his or her own voice. For example, after designating "1" as a shortcut key, a voice is inputted as "Kang Suk-hee". Number keys can be entered in the same way.

Then, the input voice signal is converted into voice data (S330). The voice processing unit 70 converts the input analog voice signal into voice data.

Finally, the converted voice data is stored in the corresponding area of the storage unit (S340). That is, if the converted voice data is voice data for the number key, it is stored in the area for storing the number data. If the converted voice data is a character string for the shortcut key, it is stored in the area for storing the character string.

Although illustrated and described in the present embodiment limited to a portable terminal, the present invention is not limited to this, it is of course applicable to various communication devices such as a general telephone, pager, walkie-talkie, computer.

In addition, although the string data, the voice data, and the voice extraction module are all provided in one storage unit in the present embodiment, a text data storage unit for storing the string data and a voice data storage unit for storing the voice data may be further added as necessary. It is also possible to provide.

According to the portable terminal having the key input voice transmission function, the portable terminal having the lower cost key input voice transmission function can be provided by implementing the voice signal transmission function for the key input in software. have.

In addition, there is an effect that can be transmitted to the character string corresponding to the input shortcut key when the input of the phone number as well as the input of the shortcut key.

In addition, the controller may perform a voice synthesis function for synthesizing voice data for the phoneme, thereby transmitting a voice corresponding to the shortcut key regardless of the change of the shortcut key.
