Hereinafter, a method for quickly moving the learning voice file forward or backward according to the present invention will be described in detail.

3A to 3C are graphs for explaining the principle of speed control according to the present invention, which is a graph comparing a general playback time and a fast playback time by receiving a previous fast moving key input.

First, when the controller 210 receives a training file play command from the user, the controller 210 reads the training file play program from the program storage unit 242 and displays the training file play program on the flat panel display 262. The stored learning file is read, and the compressed learning file is interpreted using the codec of the program storage unit 242 and then sent to the voice signal processing unit 250. Thereafter, the audio signal processor 250 converts the received digital learning file into an analog and outputs the analog learning file to the speaker 254. FIG. 3A illustrates a part of the analog learning file 300, that is, the lead line 310 (read). The output is shown to the part where the line) is located. The progress of the lead line 310 is to be moved from left to right.

Next, FIG. 3B shows the position of the lead line 310 when playing at the normal speed for a predetermined time, Δt, in the state of FIG. 3A. Reference numeral 311 denotes the position of the lead line before Δt time, that is, FIG. Indicate the listener line position at 3a.

3C is a result of performing fast playback for Δt by receiving the fast forward key input from the user in the state of FIG. 3A. The fast forward playback is performed by the controller 210 receiving the fast forward command from the user. A quick reproducing command is issued, and the voice signal processor 250 receiving the command is achieved by adjusting the speed of the output signal, that is, the movement of the lead line 310.

Thus, comparing FIG. 3B and FIG. 3C, it can be seen that during DELTA t, the lead line of FIG. 3C reproduces a larger amount of analog signals than the lead line 310 of FIG. 3B.

4 is a flowchart illustrating a fast moving method when playing a learning file according to the present invention.

As shown in Fig. 4, in step S11, it is determined whether there is a key input from the user. As a result of the determination in step S11, if there is no key input, step S11 is repeated until there is a key input, and if there is a key input, the flow advances to step S13 to determine whether or not a learning file reproduction command is issued. As a result of the determination in step S13, if it is not a learning file play command, the process proceeds to step S33 to execute a command corresponding to a key input. In the case of a learning file play command, the process proceeds to step S15 to learn from the program storage unit 242. The file playback program is selected and executed, and output to the flat panel display 262.

In step S17, the selected learning file is played back. In step S19, it is determined whether there is a key input from the user. As a result of the determination in step S19, if there is no key input, step S19 is repeated until there is a key input, and if there is a key input, the flow advances to step S21 to determine whether it is a fast forward command. As a result of the determination in step S21, in the case of the previous fast movement command, the flow advances to step S23 to start the early rapid movement. As a result of the determination in step S25, if it is not the backward fast moving command, the control proceeds to step S33 to perform a command corresponding to the key input.

After starting the fast movement in step S23 or S27, it is determined whether there is no key input in step S29. If the key input is continuously detected as a result of the determination in step S29, the fast forward or backward movement is continued, and if there is no key input, that is, if the key input is stopped, the process proceeds to step S31 to stop the quick movement and then moves back to step S19. do.

On the other hand, by pressing the command of the play speed control key button as a toggle, it can be quickly played, and if pressed again, it can be played at the original speed, and the user can set the speed to 1.5 times, 2 times, 3 times, etc. You can also do that.

The control method of the mobile communication terminal having the language learning function of the present invention is not limited to the above-described embodiment, but can be modified in various ways within the scope of the technical idea of the present invention.

According to the control method of a mobile communication terminal having a language learning function as described above, a speed control key button is provided on the outside of the mobile communication terminal, and the program storage unit of the internal memory can process a learning file. Equipped with a program to be able to move quickly forward or backward when playing the learning voice file, it is possible to move quickly to the user's desired parts, it is possible to efficiently manage the learning and learning time.
