A score of 0 may be non-response, profanity, or profanity, and a score of 5 may be defined as a language ability above quasi-native speakers, not actual English native speakers. This is because students who have actually lived in English-speaking countries for more than 10 years have actually defined this student's response as a five-point benchmark. The subscale can consist of a scale of 0.5 to 1 to 5 points. That is, it can be composed of nine scales such as 0, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5,

Two scorers may share scoring criteria with each other and adjust the difference through a two-hour scorer training process for scoring. At this time, a benchmark can be set for the scores of 1, 2, 3, 4, and 5 points, and the demonstration score can be completed about 5 times to complete the preparation for scoring. In addition, scoring can be performed in a separate space. At this time, the given time can be set to one week, which can be changed.

Scoring can be done in a way that gives both an aggregate score and an analytical score. An individual analytical scoring score may be assigned to each item for each examinee's response, and then an overall score may be assigned independently. If there is a difference of more than 1 point between the results of two scoring, the final score can be given through further consultation. The following is an empirical scoring sequence and is very similar to the top-down teaching method. This method is an analytical method based on the scoring experience of a long time. For example: 1) "Task completion" is first scored and then graded 2) "Holistic Score" 3) "Coherence" 4) "Fluency & Pronunciation" 5) "Language use "-> 6) A method such as" Grammar "may be used.

The foreign language (English) speaking evaluation system according to the embodiment of the present invention may further include a test management module, a questionnaire test item creation module, a score module, and a score post-evaluation module (web site).

 The test management module may provide examinee account management, evaluator management, various inquiry screens, examinee scores and feedback confirmation screens, online bulletin boards and communities.

The test taker test item producing module can provide a participant log / logout screen, an item configuration screen, an option screen, video or audio evaluation selection, item text insertion, preparation and response time adjustment,

The scoring module may provide a scorer login / logout screen, examinee selection, test item selection, examinee response listening, score and feedback cycle, and the like.

In order to perform the above functions, the database may be configured as a MongoDB collection as shown in Table 4. In order to perform all the functions of the server 200, the server 200 may be constructed to provide a " Restful form " utilizing the "Node JS" language.

You can create a "collection of MongoDB" schema as follows to store data for the foreign language speaking evaluation test.

The server 200 may construct a "Node JS App" as shown in Table 5 for the "Restful" service.

As described above, the speech evaluation system and the evaluation method using the mobile terminal according to the embodiment of the present invention perform a speech evaluation using a mobile terminal (for example, a smart phone, a tablet PC, etc.) By transmitting the evaluation result to the mobile terminal, the cost for evaluating the foreign language can be reduced, and the foreign language speech evaluation can be performed quickly and conveniently.

The speech evaluation system using the mobile terminal and the evaluation method thereof according to the embodiment of the present invention can be applied to a mobile terminal (smart phone, tablet PC, etc.) in order to overcome the limitation of the language speaking language evaluation method, ) In order to improve the completeness of language performance evaluation by performing a foreign language speaking evaluation.
