Description

Description FOREIGN LANGUAGE STUDYING DEVICE FOR IMPROVING

FOREIGN LANGUAGE STUDYING EFFICIENCY, AND ONLINE FOREIGN LANGUAGE STUDYING SYSTEM USING THE

SAME

Technical Field

[1] The present invention relates, in general, to a foreign language learning device and, more particularly, to a foreign language learning device that indicates the pronunciation characteristics of foreign languages so as to make them easily perceivable, thereby considerably improving the efficiency of foreign language learning. Background Art

[2] In modern society, which is becoming globalized, a good command of foreign languages is necessitated, so that enthusiasm for learning foreign languages, such as English or Chinese, is spreading all over the world.

[3] Although various foreign language learning devices are being developed to meet the above phenomenon and necessity, conventional foreign language learning devices, such as electronic dictionaries, indicate only phonetic symbols for foreign language words, but do not reflect the pronunciation characteristics of the foreign language as they are.

[4] In the case of English, which is most generally used in international diplomacy and trade, English is a stress-timed language, unlike Korean, which is a syllable-timed language. That is, English is a language that has length, pitch and stress in pronunciation. In order to accurately pronounce English words or sentences, it is important to pronounce English words or sentences while considering the unique characteristics of the pronunciation of English.

[5] In spite of the above-described difference, the conventional foreign language learning devices, such as electronic dictionaries, represent English words uniformly without consideration of the phonetic characteristics of English, so that there is a problem in that it is difficult to learn the accurate pronunciation of English.

[6] In the case of a stress-timed language, when the listening and speaking of a foreign language is learned without the understanding of the phonetic characteristics of the foreign language, it is difficult to learn the accurate length, pitch and stress of the pronunciation of the foreign language. Accordingly, at the time of having a conversation with a native speaker, it is difficult to catch the native speaker's speaking, and a learner pronounces the foreign language based on Korean and, thus, the native speaker cannot understand the learner's speaking, so that there is a hindrance in communication.

[7] Furthermore, when a stress-timed foreign language is learned using the conventional foreign language learning devices as described above, it is difficult to efficiently learn the foreign language. Accordingly, it is difficult to have a good command of the corresponding foreign language, and a considerably long period of time is required to have a good command of the corresponding foreign language. Disclosure of Invention Technical Problem

[8] Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and an object of the present invention is to provide a foreign language learning device that indicates phonetic information that enables the phonetic characteristics of a foreign language to be easily perceived, so that the length, pitch and stress of the foreign language can be easily acquired at the time of learning the foreign language, and accurate pronunciation can be used.

[9] Another object of the present invention is to provide a foreign language learning device that allows pronunciation based on the characteristics of foreign languages to be accurately and easily learned, so that an overall command of foreign languages, including the ability to speak the foreign languages as well as the ability to listen to the foreign languages, can be improved in a short period of time. Technical Solution

[10] In order to accomplish the above objects, the present invention provides a foreign language learning device used for foreign language learning so as to improve foreign language learning efficiency, including an input unit for receiving foreign language words and commands to select or direct operations of the foreign language learning device; a phonetic symbol storage unit for storing phonetic symbols for a plurality of foreign language words; a display unit for displaying phonetic information for the foreign language words input from the input unit; and a control unit for receiving the foreign language words input through the input unit, searching for phonetic symbols corresponding to the received foreign language words in the phonetic symbol storage unit, creating the phonetic information for the corresponding words based on the phonetic symbols, and transmitting the phonetic information to and outputting the phonetic information on the display unit; wherein the control unit creates the pronunciation information in such a way as to indicate the length of pronunciation by repeating a phonetic symbol or alphabet letter of a corresponding vowel, indicate the pitch of pronunciation by varying the height of the phonetic symbol or alphabet letter, and indicate the stress of pronunciation by enlarging a portion affixed with a stress mark at a predetermined magnification, based on the phonetic symbols. [11] Preferably, the stress of pronunciation is indicated by adjusting thickness, rather than size, according to the stress, or by adjusting thickness as well as size.

[12] More preferably, the foreign language learning device further includes a voice information storage unit for storing voice information about the plurality of foreign language words and a voice output unit for outputting the voice information, and the control unit simultaneously creates phonetic information about the foreign language words input through the input unit and searches for corresponding voice information in the voice information storage unit, and displays the created phonetic information on the display unit and outputs the found voice information to the voice output unit.

[13] In order to accomplish the above objects, the present invention provides a foreign language learning system for foreign language learning using a wired/wireless network so as to improve foreign language learning efficiency, including a terminal device connected to the wired/wireless network, and configured to receive foreign language words and commands to select or direct operations of the foreign language learning system; a phonetic symbol database for storing phonetic symbols for a plurality of foreign language words; and a phonetic information provision server connected to the wired/wireless network, and configured to search for phonetic symbols corresponding to the received foreign language words in the phonetic symbol database and create the phonetic information based on the found phonetic symbols when receiving the foreign language words through the input unit, to transmit the phonetic information to the terminal device, and to output the phonetic information on a display unit of the terminal device; wherein the phonetic information provision server creates the pronunciation information in such a way as to indicate length of pronunciation by repeating a phonetic symbol or alphabet letter of a corresponding vowel, indicate pitch of pronunciation by varying height of the phonetic symbol or alphabet letter, and indicate stress of pronunciation by enlarging a portion affixed with a stress mark at a predetermined magnification, based on the phonetic symbols.

[14] According to the foreign language learning device of the present invention, pronunciation based on the characteristics of foreign languages can be accurately and easily learned. Advantageous Effects

[15] According to the present invention, phonetic information enabling the phonetic characteristics of foreign languages to be easily perceived is indicated, so that the length, pitch and stress of the pronunciation of a foreign language can be easily acquired at the time of learning the foreign language, and accurate pronunciation can be used.

[16] Furthermore, pronunciation based on the characteristics of foreign languages can be accurately and easily learned, so that an overall command of foreign languages, including the ability to speak the foreign languages as well as the ability to listen to the foreign languages, can be improved in a short period.

Mode for the Invention [31] Preferred embodiments of the present invention are described in detail with reference to the accompanying drawings below. [32] FlG. 1 is a schematic diagram illustrating the construction of a foreign language learning device according to an embodiment of the present invention. [33] As illustrated in FlG. 1, the foreign language learning device of the present invention includes an input unit 11, a phonetic symbol storage unit 13, a display unit

15 and a control unit 17. [34] Although, in the following embodiment, the case where the target foreign language is English is taken as an example, the present invention is not limited to English, but can be applied to any stress-timed language that has length, pitch and stress. [35] The input unit 11 is configured such that a learner can input English words or commands to select and direct the operations of the foreign language learning device of the present invention. The input unit 11 is installed on a specific portion of the outside of the foreign language learning device, and is provided with a plurality of keys enabling the input of alphabet letters and commands.

[36] Although a keypad is generally used as the input unit, the input unit is not limited to the keypad, but any device enabling the input of alphabet letters or commands, including a touch screen, can be used as the input unit.

[37] In the phonetic symbol storage unit 13, phonetic symbol data about a plurality of English words is stored. In this case, the phonetic symbol data stored in the phonetic symbol storage unit 13 is the conventional phonetic symbols of English words, which are generally used phonetic symbols.

[38] Phonetic information created by the control unit 17 for a word input by the input unit 11 is displayed on the display unit 15. Although a Liquid Crystal Display (LCD) may be used as the display unit 17, the display unit is not necessarily limited to the LCD, but any device capable of displaying phonetic information to allow the information to be visibly recognized may be used.

[39] The control unit 17 receives the English word input through the input unit 11, searches the phonetic symbol storage unit 13 for phonetic symbols corresponding to the received word, creates phonetic information about the corresponding word based on the phonetic symbols, and transmits the created phonetic information to the display unit 15 such that the created phonetic information is displayed on the display unit 15.

[40] The method in which the control unit 17 creates phonetic information for a corresponding word based on phonetic symbols is described in detail below. [41] For this purpose, the characteristics of the pronunciation of English, which is a stress-timed language, are described below in more detail. As described above, English is a stress-timed language, and has length, pitch and stress in its pronunciation. The length, pitch and stress of English pronunciation are related to the sonority of the English alphabet. Here, the term "sonority" refers to the relative size of sound that is pronounced using the same length, pitch and stress. The highest sonority values of respective phonetic symbols are illustrated in the following [Example I].

[42] [Example 1] [43]

Figure imgf000006_0001
Figure imgf000007_0001

[44] As understood from the above Example 1, the vowels of the English alphabet generally have high sonorities, with the consequence that almost all of the length, pitch and stress in English are determined depending on vowels.

[45] The sound structure of an English vowel is different from that of a Korean one. A single English vowel, or a compound English vowel in which a plurality of vowels is successively included, has a successive sound structure that is composed of a beginning sound, the highest sound and the lowest sound. If this structure is to be compared with a figure, it may be compared with a triangle.

[46] The following [Example 2] compares the sound structure of an English vowel to that of a Korean vowel on a four-line sheet, the English vowel and the Korean vowel being considered to be the same by common persons.

[47] [Example 2] [48]

Figure imgf000007_0002

[49] As understood from [Example 2], the vowel 'D' in Korean forms a square single- time sound structure that has a short and monotonous interval, whereas the vowel in English corresponding to the vowel 'D' in Korean forms a triangular triple-time sound structure that is long and has pitch. Such a sound structure corresponds not only to this vowel, but also to every vowel in English in the same manner. That is, every vowel in English has a triangular sound structure in which a beginning sound, the highest sound and the lowest sound occur in sequence.

[50] The triangular sound structure of English is based on each syllable of English, and not only a single vowel but also a compound vowel forms a single triangular sound structure. That is, a compound vowel as a whole has a triangular sound structure, like a single vowel, the triangular sound structure of such a compound vowel being il¬ lustrated in the following [Example 3].

[51] [Example 3]

[52] bathe"

_[_Jbβiά_]_

Figure imgf000008_0001

[53] As understood from [Example 3], a compound vowel in which a plurality of vowels exists in a single syllable forms a single triangular sound structure as a whole. However, such a compound vowel is different from a single vowel in that the lowest sound of the compound vowel is lower than that of the single vowel and the lowest sound of the compound vowel is longer than that of the single vowel.

[54] Furthermore, when even a single vowel has a long sound mark, the lowest sound of the long vowel is lower than that of a simple single vowel and the long vowel is longer overall than is the simple single vowel, like a compound vowel. The triangular sound structure of such a long vowel is illustrated in the following [Example 4].

[55] [Example 4] [56]

Figure imgf000008_0002

[57] As understood from the triangular sound structure of a compound vowel and a long vowel, the compound vowel and the long vowel are similar to a single vowel in that they all have triangular sound structures each of which is composed of a beginning sound, the highest sound and the lowest sound, except that the length of the lowest sound of each of the compound vowel and the long vowel is longer than that of the single vowel, and the pitch of the lowest sound of each of the compound vowel and the long vowel is lower than that of the single vowel. [58] Meanwhile, the sonority of a single vowel or compound vowel existing in each syllable of an English word varies with the location of the stress of the corresponding English word. For example, in the case where a vowel has a primary stress, about 10 is added to the original sonority value of a corresponding vowel. In the case where a vowel has a secondary stress, about 5 is added to the original sonority value of a corresponding vowel (see [Example I]).

[59] In the foreign language learning device according to the present invention, the control unit 17 creates phonetic information, which enables a sound structure unique to English to be visually perceived, about an English word input from the input unit 11 based on the phonetic symbols thereof, and displays the phonetic information on the display unit 15.

[60] The method of creating such phonetic information is described in detail below. The control unit 17 searches the phonetic symbol storage unit 13 for phonetic symbols for an English word input from the input unit 11, and displays the length of a single vowel in such a way as to display the phonetic symbol of a single vowel three times based on found phonetic symbols while displaying the pitches of English pronunciation in descending order of a second phonetic symbol (highest sound), a first phonetic symbol (beginning sound) and a third phonetic symbol (lowest sound) so as to allow the pitches of the English pronunciation to be perceived, as described above.

[61] Furthermore, in the case where a compound vowel or long vowel exists in phonetic symbols, the five phonetic symbols of the compound vowel or long vowel are displayed in such a way as to display first and second phonetic symbols in a manner identical to that in which the first and second phonetic symbols of a single vowel are displayed, and to display the third to fifth phonetic symbols thereof such that the pitches of the third to fifth phonetic symbols of the compound vowel or long vowel sequentially decrease. That is, all of the pitches are displayed in descending order of a second phonetic symbol, a first phonetic symbol, a third phonetic symbol, a fourth phonetic symbol and a fifth phonetic symbol.

[62] Meanwhile, the generally used phonetic symbols of English are affixed with first and/or secondary stress marks so as to indicate the stresses of the phonetic symbols. The control unit 17 determines whether one or more stresses exist in the phonetic symbols, and displays the stresses so as to enable the stresses to be visually perceived by displaying a vowel having a primary stress mark at a magnification of 200% of the original size thereof and displaying a vowel having a secondary stress at a magnification of 150%.

[63] Alternatively, the stress of pronunciation may be displayed by adjusting thickness, rather than size, according to the stress, or can be more clearly displayed by adjusting thickness as well as size. [64] Although, in the present embodiment, phonetic information is created by repeatedly displaying the phonetic symbols of a corresponding word at the time of creating the phonetic information using the control unit 17, the phonetic information of the corresponding word can be created by using and repeatedly displaying the alphabet letters of the corresponding word, rather than the phonetic symbols thereof. The following [Example 5] illustrates examples in which phonetic information about English words and English sentences is created using the letters of the alphabet themselves.

[65] [Example 5]

[67]

Figure imgf000010_0002

[68] When phonetic information is displayed using the alphabet letters of English words themselves, there is the advantage of being capable of perceiving the sound structure of English using English words themselves without viewing phonetic symbols.

[69] The above-described foreign language learning device according to the present invention displays the pronunciation of each vowel, which is most important for the precise pronunciation of an input English word, in the above-described triangular form that is composed of a beginning sound, the highest sound and the lowest sound as phonetic information about the corresponding word, and enlarges the size of a corresponding symbol according to the affixture of a stress mark, so that a learner can learn the corresponding word while visually perceiving the length, pitch and stress of the pronunciation of the word at the time of learning the word, therefore the learner can easily perceive and learn the phonetic characteristics of English, which is a stress- timed language.

[70] Meanwhile, although, in the above-described embodiment, English is taken as an example of a stress-timed language, the present invention is not limited to English, but may be applied to any stress-timed language at the time of creating the phonetic information.

[71] A method of creating phonetic information about Chinese, which is another stress- timed language, is described below.

[72] Chinese has four tones, and the respective tones have different lengths, pitches and stresses. The respective tones are briefly described below. The sound of the first tone is pronounced from a somewhat high beginning sound to a somewhat low final sound, but the difference between the beginning sound and the final sound is not significant. The length of the sound of this tone is the second shortest of the four tones.

[73] The sound of the second tone is pronounced from a relatively low sound to the highest sound, and the length of the sound of this tone is the second longest of the four tones. The third tone is a tone having a curve. The sound of this tone is pronounced from a sound slightly low compared to that for the second tone through a lower sound rapidly to a high sound, and the length of the sound of this tone is the longest of the four tones.

[74] Finally, the sound of the fourth tone is rapidly pronounced from the highest sound to the lowest sound, and the length of the sound of this tone is the shortest of the four tones.

[75] The typical phonetic symbols for the four tones of Chinese are illustrated in the following [Example 6].

[76] [Example 6]

[81] Furthermore, the phonetic information created in the above-described manner by the foreign language learning device according to the present invention and typical phonetic symbols are compared in the following Example 8. [82] [Example 8]

[83]

Figure imgf000012_0001

[84] In [Example 8], the upper portion indicates typically used phonetic symbols, while the lower portion indicates phonetic information created by the foreign language learning device according to the present invention.

[85] As appreciated above, the phonetic information created and displayed by the foreign language learning device according to the present invention displays the length, pitch and stress of the pronunciation of Chinese, which is another stress-timed language, so as to make it clearly visually perceived, so that a learner can easily perceive and learn the phonetic characteristics of Chinese.

[86] The method of operating the above-described foreign language learning device according to the present invention is described in detail below with reference to FIG. 2.

[87] FIG. 2 is a flowchart illustrating the operation of the foreign language learning device of FTG. 1.

[88] First, a word is input from the input unit 11 at step S21.

[89] The control unit 17 searches the phonetic symbol storage unit 13 for phonetic symbols corresponding to the input word at step S22.

[90] Thereafter, the control unit 17 creates phonetic information, which allows the length and pitch of pronunciation to be visually perceived, based on the found phonetic symbols and depending on the length and pitch at step S23. At the time of creating such phonetic information, the length of pronunciation is indicated by repeating the phonetic symbol or alphabet letter of a corresponding vowel, while the pitch of the pronunciation is indicated by varying the displayed heights of the repeated phonetic symbols or alphabet letters.

[91] Thereafter, the control unit 17 determines whether the corresponding phonetic symbols have been affixed with a stress mark at step S24.

[92] If, as a result of the determination, it is determined that the corresponding phonetic symbols have not been affixed with a stress mark, the created phonetic information is transferred to the display unit 15 and is then displayed at step S25.

[93] In contrast, if, as a result of the determination, it is determined that the corresponding phonetic symbols have been affixed with a stress mark, the portion affixed with a primary stress mark is enlarged at a magnification of 200%, the portion affixed with a secondary stress mark is enlarged at a magnification of 150% at step S26, and this information is transmitted to and displayed on the display unit 15.

[94] Alternatively, the stress of pronunciation may be indicated by adjusting thickness, rather than size, according to the stress, or can be more clearly displayed by adjusting thickness as well as size.

[95] Meanwhile, the foreign language learning device according to the present invention further includes a voice information storage unit for foreign language words and, thereby, can further improve a learner's learning efficiency.

[96] With reference to FlG. 3, another embodiment of the present invention, further including the voice information storage unit for foreign language words, is described below.

[97] FlG. 3 is a schematic diagram illustrating a foreign language learning device according to another embodiment of the present invention.

[98] As seen from FlG. 3, the foreign language learning device of FlG. 3 further includes a voice information storage unit 36 and a voice output unit 38, in addition to the foreign language learning device of FlG. 1. The remaining elements are the same and are assigned the same reference characters as those of FlG. 1, and descriptions thereof are omitted here.

[99] Voice information corresponding to the phonetic symbols of a plurality of words stored in the phonetic symbol storage unit 13 is stored in the voice information storage unit 36.

[100] Furthermore, voice information found in the voice information storage unit 36 is output from the voice output unit 38. Any device capable of outputting voice, such as a speaker, may be used as the voice output unit 38.

[101] In this case, the control unit 17 searches for phonetic symbols corresponding to a word input through the input unit 11 in the phonetic symbol storage unit 13, searches for corresponding voice information in the voice information storage unit 36, displays phonetic information generated from the phonetic symbols on the display unit 15, and outputs the corresponding voice information through the voice output unit 38.

[102] Selectively, the display of the phonetic information on the display unit 15 and the output of the voice information to the voice output unit 38 may be synchronized with each other so as to allow the display and output be performed at the same speed.

[103] With reference to FlG. 4, the operation of the foreign language learning device of

FlG. 3 is described in detail below. FlG. 4 is a flowchart illustrating the operation of the foreign language learning device of FlG. 3.

[104] First, a word is input from the input unit 11 at step S41.

[105] The control unit 17 searches for phonetic symbols corresponding to the input word in the phonetic symbol storage unit 13, and searches for corresponding voice information in the voice information storage unit 36 at step S42.

[106] Thereafter, the control unit creates phonetic information based on the found phonetic symbols and according to the length and pitch of pronunciation so as to make them visually perceivable at step S43. The method of creating the phonetic information is the same as described above, so that a detailed description thereof is omitted here.

[107] Thereafter, the control unit 17 determines whether the phonetic symbols have been affixed with one or more stress marks at step S44.

[108] If, as a result of the determination, it is determined that the phonetic symbols have not been affixed with one or more stress marks, the created phonetic information is transmitted to and displayed on the display unit 15 and, at the same time, the corresponding voice information is output through the voice output unit 38 at step S45.

[109] In contrast, if, as a result of the determination, it is determined that the phonetic symbols have been affixed with one or more stress marks, the portion affixed with a primary stress mark is enlarged at a magnification of 200% and the portion affixed with a secondary stress mark is enlarged at a magnification of 150% at step S46, this information is transmitted to and displayed on the display unit 15, and corresponding voice information is output through the voice output unit 38.

[110] Alternatively, the stress of pronunciation may be displayed by adjusting thickness, rather than size, according to the stress, or can be more clearly displayed by adjusting thickness as well as size.

[Ill] The above-described foreign language learning device according to the present invention displays phonetic information allowing the phonetic characteristics of a foreign language to be visually perceived, and enables corresponding voice information to be audibly perceived, thereby further improving the learner's learning efficiency.

[112] Meanwhile, the foreign language learning device according to the present invention may be implemented online using a wired/wireless network, which is described in detail below with reference to FlG. 5.

[113] FlG. 5 is a schematic diagram illustrating the construction of an online foreign language learning system according to another embodiment of the present invention.

[114] As seen from FlG. 5, the online foreign language learning system according to another embodiment of the present invention includes a terminal device 51, a wired/ wireless network 53, a phonetic symbol database 55, a voice information database 57, and a phonetic information provision server 59. [115] The terminal device 51 is connected to the wired/wireless network 53, and includes a display unit (not shown) and a voice output unit (not shown). A Personal Computer (PC), a PDA and a mobile communication terminal may be used as the terminal device 51.

[116] Phonetic symbols for a plurality of foreign language words are stored in the phonetic symbol database 55, and voice information about a plurality of foreign language words is stored in the voice information database 57.

[117] The phonetic information provision server 59 is connected to the wired/wireless network 53, and when receiving a signal requesting phonetic information about a foreign language word from the terminal device 51, searches the phonetic symbol database and the voice information database and creates the phonetic information, transmits the created phonetic information and the found voice information to the terminal device 51, and causes the created phonetic information and the found voice information to be respectively output from the display unit and voice output unit of the terminal device 51.

[118] In that case, the methods of creating and outputting phonetic information and voice information are the same as described above, and detailed descriptions thereof are omitted here.

[119] When the foreign language learning device according to the present invention is implemented on a wired/wireless network as described above, foreign languages can be conveniently and efficiently learned both in a current environment in which access to a network can be easily made and in a future environment in which a ubiquitous system enabling access to a network anytime and anywhere is established.

[120] Meanwhile, alternatively, the foreign language learning device according to present invention may create and display phonetic information using different colors for a vowel, a voiced consonant and a voiceless consonant that constitute the pronunciation of a foreign language word.

[121] By displaying different pronunciation types using different colors, the difference of pronunciation can be clearly perceived and learned at the time of learning foreign languages, so that learning efficiency can be further improved.

[122] Although the present invention has been described in detail above in conjunction with the specific embodiments, the present invention is not limited to the above- descried embodiments, but various modifications can be made by those skilled in the art within the technical spirit of the present invention. Industrial Applicability

[123] According to the present invention, phonetic information enabling the phonetic characteristics of foreign languages to be easily perceived is indicated, so that the length, pitch and stress of the pronunciation of a corresponding foreign language can be easily acquired at the time of learning the foreign language and accurate pronunciation can be used, so that the present invention can be applied to and used in foreign language learning devices and foreign language learning systems implemented on wired/wireless networks.

[2] The foreign language learning device as set forth in claim 1, wherein the stress of pronunciation is indicated by adjusting thickness, rather than size, according to the stress, or by adjusting thickness as well as size.
[3] The foreign language learning device as set forth in claim 1, further comprising: a voice information storage unit for storing voice information about the plurality of foreign language words; and a voice output unit for outputting the voice information; wherein the control unit simultaneously creates phonetic information about the foreign language words input through the input unit and searches for corresponding voice information in the voice information storage unit, and displays the created phonetic information on the display unit and outputs the found voice information to the voice output unit.
[4] The foreign language learning device as set forth in claim 3, wherein the display of the phonetic information on the display unit and the output of the voice information to the voice output unit are synchronized with each other at an identical speed. [5] The foreign language learning device as set forth in any one of claims 1 to 4, wherein, when the foreign language words are English words, the phonetic information created for each of the input English words has a triangular sound structure in which phonetic information about a vowel is composed of a beginning sound, a highest sound, and a lowest sound.
[6] The foreign language learning device as set forth in claim 5, wherein, when the vowel is a compound vowel or long vowel, the lowest sound is lengthened compared to a case where the vowel is a single vowel.
[7] The foreign language learning device as set forth in any one of claims 1 to 4, wherein, when the phonetic information is created, a vowel affixed with a primary stress mark is indicated to be larger than that of a vowel affixed with a secondary stress mark.
[8] The foreign language learning device as set forth in any one of claims 1 to 4, wherein the phonetic information is indicated using different colors for a vowel, a voiced consonant and a voiceless consonant.
[9] A foreign language learning system for foreign language learning using a wired/ wireless network so as to improve foreign language learning efficiency, comprising: a terminal device connected to the wired/wireless network, and configured to receive foreign language words and commands to select or direct operations of the foreign language learning system; a phonetic symbol database for storing phonetic symbols for a plurality of foreign language words; and a phonetic information provision server connected to the wired/wireless network, and configured to search for phonetic symbols corresponding to the received foreign language words in the phonetic symbol database and create the phonetic information based on the found phonetic symbols when receiving the foreign language words through the input unit, to transmit the phonetic information to the terminal device, and to output the phonetic information on a display unit of the terminal device; wherein the phonetic information provision server creates the pronunciation information in such a way as to indicate length of pronunciation by repeating a phonetic symbol or alphabet letter of a corresponding vowel, indicate pitch of pronunciation by varying height of the phonetic symbol or alphabet letter, and indicate stress of pronunciation by enlarging a portion affixed with a stress mark at a predetermined magnification, based on the phonetic symbols.
[10] The foreign language learning device as set forth in claim 9, further comprising a voice information database for storing voice information about the plurality of foreign language words; wherein the terminal device comprises a voice output unit for outputting the voice information; and wherein the phonetic information provision server simultaneously creates phonetic information about the foreign language words input through the terminal device and searches for corresponding voice information in the voice information database, transmits the created phonetic information and the found voice information to the terminal device, and outputs the created phonetic information and the found voice information to the display unit and the voice output unit, respectively.
