Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. Figure 1 shows a functional diagram for performing the operation of the present invention, Figure 2 is a graph for explaining the relationship between the foreign language original sound and the signal recorded from the user in accordance with the present invention, Figures 3 and 4 It is a flowchart for explaining the operation of the invention.

As shown in the illustrated drawings, a first memory 105 for downloading or storing foreign language original sound information from a computer terminal, a predetermined communication terminal or a compact disk, and a second memory for storing information recorded from a user as a digital signal ( 107) a DSP for controlling output of pre-stored information from the memory and input of information into the memory, a sound reproduction speed control, and a synchronous control of a peripheral device; an output port of the DSP 101 Digitized information connected to and stored in the memory, for example, includes an MP3 decoder 109, a D / A converter 111, and an amplifier 113 for decoding MP3 file information.

The input port of the DSP 101 is connected to the filter 117, the A / D converter 115 for the non-signal removal of the analog signal input from the microphone, in addition to the keypad 119 for the user control signal input ) And a display unit 103 for displaying caption information stored in the first memory 105.

The MP3 file information may include sound source information of a foreign language and text corresponding to the sound source information, that is, sentence information, and may be sound information and text information corresponding thereto. Here the text information of the sound information will be lyrics. Therefore, the information stored in the first memory 105 is composed of sound source information (sound information) and text (sentence information, lyrics information), and the corresponding text is assigned to each syllable of the sound source information and correspondingly. The unique number is assigned to the information to synchronize with each other.

In the present invention, the synchronization signal of the sound source information and the text information is matched with the start byte of the subtitle data, and the sequence information of the syllable is inserted into the start byte of the sound source information and the text information (subtitle), so that the sound source information and Synchronization is performed when text information is reproduced. This reproduction synchronization signal is intended to ensure accurate synchronization even after the system uses slow playback, fast playback, rewind and fast forward modes.

In other words, if the synchronization between the sound source information and the text information for each frame is required, a number of frames are required to be calculated, and in spite of these calculations, the sound quality degradation due to an error with the sampling frequency of the system is prevented.

First, the recording process according to the present invention will be described with reference to FIGS. 2 and 3, and a user downloads text information corresponding to foreign language original sound information and original sound information from a computer (S301), and the original sound information and text information are respectively described. As a unique number is assigned in syllable units, the foreign language original sound information and the text information are stored in the first memory 105 as a single file. The file type may be an MP3 file as an embodiment, and may be downloaded with a predetermined protocol as other digitized information. Of course, data processing of the DS 101 is performed according to the above protocol.

The user confirms the completion of the language information download through the keypad 119 and the display 103, and performs a separate key operation to reproduce the downloaded information. The reproduction transfers the information stored in the first memory 105 to the MP3 decoder 109 to select only foreign language sound source information. The text information corresponding thereto is provided to the display unit 103 under the control of the DS 101. The synchronization of the foreign language sound source information and the corresponding text information is performed through the synchronization information for each syllable described above, and the text display is performed. Is to be output with a certain timing.

The foreign language sound source information provided through the MP3 decoder 109 is converted into sound information analogized through the D / A converter 111 and provided to the speaker or the earphone through the amplifier 113. The DSP 101 not only provides a sampling frequency of the ADC converter 111 but also controls the amplification gain of the amplifier 113 to be controlled by the keypad 119.

On the other hand, when the user listens to foreign language sound source information reproduced through the speaker or earphone, and wants to compare with the pronunciation of the pronunciation from it, the user switches to the recording confirmation mode through the keypad (119) (S303). The DS 101 detects this and reads the foreign language original sound information and the text information corresponding thereto in one syllable unit, which are stored in the first memory 105, and the second memory 107 is enabled to store the information. Then, the state is switched to the light state.

Foreign language original sound information stored in the first memory 105 is provided to the die converter 111 via the MP3 decoder 109, and the analogized original sound information is provided to the speaker through the amplifier 113. As shown in Fig. 2, foreign language original sound reproduction is performed for a time. Here, a time may be correct to be recognized as one sentence, or may be a word unit necessary for language learning (S307).

The time a provided from the first memory 105 ends (S309), and for example, after a delay of about 0.5 seconds, a recording start signal is output (S311). The DSP 101 provides a recording start signal as a dial tone through a user's earphone or speaker, and stores time information according to the a time in a register. The user starts recording after this dial tone. The recorded signal detects only the user's voice signal through the filter circuit 117, which detects only the signal of the audible frequency and removes the remaining noise signal to determine whether the user recording information is terminated.

The user voice signal is converted into digitized information through the AD converter 115 and processed through the DSP 101. The DS 101 may set a start point of the voice signal to determine a start portion of the voice signal and store the start point of the voice signal in the second memory 107 (S313). The DS 101 counts the time a and determines whether a time corresponding to 90% of the time a has elapsed (S315). If the time has not elapsed, the user voice signal is continuously stored in the second memory 107. If the time has elapsed, a no signal of the currently input voice signal is detected (S317).

If no signal is detected, the user is currently recording, and if no signal is detected after 90% of the time a, the user recording is considered to be ended. A recording end signal is generated (S319). The recording end signal indicates that the recording time has elapsed from the user.

The user recording information recorded as described above is stored in the second memory 107 and the playback mode is selected through the keypad 119. In the reproducing mode, the foreign language original sound information previously stored in the first memory 105 is reproduced one sentence, and the user recording information previously stored in the second memory 107 is reproduced one sentence at a time. As another reproduction mode, the foreign language original sound information and the user recording information which are pre-stored in the first memory 105 and the second memory 107 are simultaneously reproduced.

The DS 101 generates a recording end signal, calculates a time from the recording start signal to input of the first user recording information, and stores the time in the internal register (S401). When another reproduction mode is selected from the keypad 119, the user recording information previously stored in the second memory 107 is reproduced (S403). The DS 101 performs a count according to the time information stored in the internal register to determine whether the time delay has been performed as much as the time information (S405).

If the time delay as much as the time information is not achieved, the user recording information of the second memory 107 is continuously reproduced. This is a delay time until the user records after the recording start signal, and the DS 101 simply outputs such a non-signal to save the time difference. On the other hand, when the time delay as much as the time information is made, the first memory 105 is enabled to reproduce the stored foreign language original sound information (S407).

At this time, the DSP 101 reproduces the foreign language original sound information and the user recording information at the same time, and reproduces the left and right sides of the earphone with respective mono signals, respectively. The user is to compare the original sound and the recording information through the foreign language original sound information and the user recording information listened to the earphone. The playback process is terminated at the same time as the recording end signal generated by the DS 101 (S409).

In the present invention, when comparing the reproduction of the original sound information and the recorded user recording information, it is possible to record while listening to the original sound information in accordance with the playback order of the digital signal, or to record after listening to the original sound information, the original sound information and the user during playback Listening to the recording information at the same time, or listening to the recording information after listening to the original sound information can improve the efficiency of language learning education.

As described above, a language learning apparatus having a recording comparison function and a language learning method using the same according to the present invention are provided for learning a language by downloading foreign language original sound information and corresponding text information for language learning through a computer and reproducing it. In the system, the user's voice information is converted into a digitized signal, processed according to a predetermined protocol, stored in a specific memory, and the stored information is controlled simultaneously or alternately with the foreign language original sound information. As the information and the recorded information of the user can be compared with each other, the effect of increasing the language learning efficiency is obtained.
