Abstract

The present invention relates to a method, an apparatus, and a computer-readable recording medium for improving at least one semantic unit set by using a phonetic sound. The method for improving a set including at least one semantic unit, in which the set including at least one semantic unit is a captured semantic unit set, includes: receiving an improvement phonetic sound according to utterance of a user; specifying an improvement semantic unit set on the basis of the improvement phonetic sound; specifying a semantic unit set as a target to be actually improved within the captured semantic unit set, as a matched semantic unit set, on the basis of correlation thereof with the improvement semantic unit set; and replacing the matched semantic unit set within the captured semantic unit set with the improvement semantic unit set.

Claims

1. A computer-implemented method for correcting errors in a captured semantic unit set including at least one semantic unit set, the method comprising:

displaying the captured semantic unit set including an incorrect semantic unit set on a display screen;

receiving, from an utterance of a user through a voice sensing unit, an analog voice signal including an improvement semantic unit set to correct the incorrect semantic unit set in the captured semantic unit set and a predetermined number of letters forming a partial spelling of the improvement semantic unit set immediately following the utterance of the improvement semantic unit set without an intervening phonetic sound uttered between the utterance of the improvement semantic unit set and the utterance of the predetermined number of letters;

converting the analog voice signal of the improvement semantic unit set to a digital signal by performing at least one of a sampling process, a quantization process, and an encoding process;

specifying, by a processor, the incorrect semantic unit set within the captured semantic unit set on a basis of correlation thereof with the improvement semantic unit set; and

replacing, by the processor, the incorrect semantic unit set within the captured semantic unit set with the improvement semantic unit set.

2. The method of claim 1, wherein the specified improvement semantic unit set is determined to be correct when the predetermined number of letters sequentially coincide with a portion of the specified improvement semantic unit set.

3. The method of claim 1, wherein the predetermined number of letters are military phonetic alphabets which sequentially coincide with a portion of the specified improvement semantic unit set.

4. A non-transitory computer-readable recording medium storing a computer program for enabling a computer to execute the method according to claim 1.

5. An apparatus for correcting errors in a captured semantic unit set including at least one semantic unit set, the apparatus comprising:

a voice sensing unit configured to receive an analog voice signal of an improvement semantic unit set according to utterance of a user to correct an incorrect semantic unit set in the captured semantic unit set displayed on a display screen;

a voice processing unit configured to convert the analog voice signal of the improvement semantic unit set to a digital signal by performing at least one of a sampling process, a quantization process, and an encoding process; and

a semantic unit improving unit, including at least one processor, configured to

receive, through the voice sensing unit from the user, the analog voice signal of the improvement semantic unit set to correct the incorrect semantic unit set in the captured semantic unit set and a predetermined number of letters forming a partial spelling of the improvement semantic unit set immediately following the utterance of the improvement semantic unit set without an intervening phonetic sound uttered between the utterance of the improvement semantic unit set and the utterance of the predetermined number of letters,

specify the incorrect semantic unit set within the captured semantic unit set on a basis of a correlation thereof with the improvement semantic unit set, and to

replace the incorrect semantic unit set within the captured semantic unit set with the improvement semantic unit set.

6. A computer-implemented method for correcting errors in a captured semantic unit set including at least one semantic unit set, the method comprising:

displaying the captured semantic unit set including an incorrect semantic unit set on a display screen;

receiving, from an utterance of a user through a voice sensing unit, an analog voice signal including an improvement semantic unit set to correct the incorrect semantic unit set in the captured semantic unit set and a predetermined reserve word and a hint word immediately following the utterance of the improvement semantic unit set without an intervening phonetic sound uttered between the utterance of the improvement semantic unit set and the utterance of the predetermined number of letters,

wherein the hint word corresponds to at least one of a word having a spelling at least partially identical or similar to that of a word in the specified improvement semantic unit set, a word having a synonymic relationship with a word in the specified improvement semantic unit set, a word having a superordinate-subordinate relationship with a word in the specified improvement semantic unit set, and a word having an associate relationship with a word in the specified improvement semantic unit set;

converting the analog voice signal of the improvement semantic unit set to a digital signal by performing at least one of a sampling process, a quantization process, and an encoding process;

specifying, by a processor, the incorrect semantic unit set within the captured semantic unit set on the basis of correlation thereof with the improvement semantic unit set; and

replacing, by the processor, the incorrect semantic unit set within the captured semantic unit set with the improvement semantic unit set.
