Referring to fig. 2, fig. 2 is a flow chart of another method for modifying dictation according to an embodiment of the invention. The method for modifying the dictation shown in fig. 2 may specifically include the following steps:
201. when receiving a dictation termination instruction, collecting dictation pictures corresponding to dictation contents by using a camera module; wherein the dictation content is written by the user according to the newspaper reading content of the electronic device.
202. Judging whether the picture quality of the dictation picture meets the identification condition, if so, executing the steps 203 to 207; if not, the process is ended.
203. And determining a target recognition rule from the preset recognition rules according to the type of the newspaper reading content.
Steps 201 to 203 are performed to detect the picture quality of the dictation picture, thereby improving the recognition efficiency of the dictation picture.
204. And determining the area in a preset border in the dictation picture as an effective area.
205. And cutting the picture in the effective area to obtain picture blocks, and setting identification serial numbers corresponding to the picture blocks.
The writing area (paper book surface or electronic book surface) of the dictation content may have a special cell and a preset border line, if the type of the dictation content is pinyin type, the special cell may be pinyin cell, if the type of the dictation content is word type, the special cell may be word cell, and if the type of the dictation content is pinyin plus word type, the special cell is comprehensive cell. The spelling unit lattice can be four-row three-line spelling lattice, the word unit lattice can be field word lattice, and the comprehensive unit lattice can be four-row three-line +field word lattice. The picture blocks obtained by cutting the picture of the effective area can be special cells with dictation content, the mode of setting the identification serial numbers corresponding to the picture blocks can be to set the number of rows and the number of columns of the picture blocks as the sorting base, and the identification serial numbers corresponding to the picture blocks are set according to the sorting base of the picture blocks.
206. And integrating the target recognition rule and the recognition sequence number to recognize the picture blocks so as to obtain a recognition result.
The following describes the target recognition rule in detail:
if the type of the above-mentioned newspaper-reading content is a pinyin type, the target recognition rule may be to determine the dictation content in a pinyin lattice as a pinyin, and sequentially recognize letters constituting the pinyin according to the sequence from left to right.
If the type of the above-mentioned newspaper-reading content is word type, the target recognition rule may be that the dictation content in a word cell is determined as a word, and whether the two words form a word is determined by detecting the distance between the left and right adjacent two words, specifically, when the distance between the left and right adjacent two words is greater than a preset value, the two words do not form a word, and when the distance between the left and right adjacent two words is less than or equal to the preset value, the two words form a word.
If the type of the above-mentioned newspaper-reading content is the spelling and word adding type, the target recognition rule involves two cases, one is the spelling and word adding case, namely comprising one spelling and one Chinese character, the other is the spelling and word adding case, namely comprising two spellings and two Chinese characters, in the embodiment of the invention, the position relationship between the spelling and the Chinese character in the integrated unit cell can be that the spelling is on the upper side, the word is on the lower side, the two are aligned in the center of the same vertical axis, if the spelling and word adding is seen as a whole, the spelling and word adding case comprises two spelling and word adding whole, and the interval between the two whole is smaller than the preset value. In pinyin word adding or recognition of pinyin word adding, in addition to referring to a target recognition rule corresponding to a pinyin type, recognition of pinyin is required to recognize a tone written in pinyin and a position of the tone.

The target modification rule is described as follows:
if the type of the reading content is pinyin type, the target correction rule may be: according to the sequence from left to right, each written letter of the identified constituent pinyin is matched with each standard letter of the constituent pinyin one by one, and when each written letter of the identified constituent pinyin is successfully matched, namely, the written strokes and the sequence of each written letter of the identified constituent pinyin are matched, the correct pinyin dictation is determined, the written strokes and/or the sequence of the identified written letters of the constituent pinyin are not matched, the incorrect pinyin dictation is determined, and the marking is carried out according to a preset marking mode (such as circle drawing);
if the types of the above-mentioned newspaper-reading content are word types, the target correction rules can be divided into two types, one is correction of the word, and the other is correction of the word, and the correction of the word is specifically: matching the writing strokes of the recognized words with standard strokes of the newspaper reading words, and marking the successfully unmatched words according to a preset marking mode; the correction of the words is specifically as follows: performing single word matching on each recognized word forming the word one by one according to the left-to-right sequence, determining that the word dictation is correct when the recognized writing strokes and the sequence of each recognized word forming the word are successfully matched, determining that the word dictation is wrong when the recognized writing strokes and/or the sequence of each recognized word forming the word are not successfully matched, and marking according to a preset marking mode;
If the type of the above-mentioned newspaper-reading content is the spelling and word type, the target correction rule mainly involves correcting the spelling and word type, when correcting the spelling and word type, the requirements of the spelling and word overall dictation are that the spelling and the word in the spelling and word overall dictation are correct, the word dictation is correct, and the spelling and word are corresponding (if the word in the spelling and word is a multitone, the written spelling is any one of a plurality of legal spellings corresponding to the word, the spelling and word are determined to be corresponding), it is required that in the spelling and word type, besides the writing strokes and sequence of all writing letters comprising the spelling are correct, the written tone and position are correct, if the spelling and word type is wrong, the spelling and/or word error is present, the spelling and word overall error is determined; the correct requirements for the dictation of the pinyin plus word include that each individual pinyin plus word contained in the pinyin plus word is correctly dictated and that the order of each individual pinyin plus word is correct. When the spelling adding word is wrong, the whole spelling adding word is marked according to a preset mode, and when the spelling adding word is wrong, the whole spelling adding word is marked according to a preset mode.
In the embodiment of the invention, in the process of correcting the pinyin and the word, if the pinyin and the word are unrecognizable, the pinyin and the word can be determined to be dictation errors.
By implementing the method, the correction efficiency of the dictation content can be improved, the acquisition efficiency and quality of the dictation picture can be effectively improved, feedback information for encouraging the user can be output to the user, the interestingness of the device is improved, parents or teachers can clearly master the learning progress of students, and the recognition efficiency of the dictation picture is improved.
