All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, a schematic structural diagram of an auxiliary method and system for reciting english words generated based on associated vocabulary according to an embodiment of the present invention is shown. The English word recitation auxiliary method based on the associated vocabulary generation comprises the following steps:
step S1, analyzing the English words input by the students to determine the word attributes of the input English words; selecting a plurality of associated English words related to the input English words in the sense of meaning from a preset English word lexicon according to the word attributes;
step S2, according to the past English word recitation history of the student, eliminating the word which is memorized after the student recites from the plurality of related English words, thereby generating a corresponding English word recitation list;
step S3, after all English words in the English word recitation list are sorted, the standard pronunciation audio frequency corresponding to each word in the English word recitation list is played in turn; and recording the actual voice formed after the student follows the standard pronunciation audio, and feeding back a corresponding reminding message of whether the words recite correctly or not to the student after analyzing the actual voice.
The beneficial effects of the above technical scheme are: the English word recitation auxiliary method based on the associated vocabulary generation generates a plurality of associated English words semantically associated with the input English words by analyzing the English words input by students, and also eliminates the words which have been previously memorized by the students, thereby avoiding the occurrence of repeated recitation of the words by the students; in addition, the student determines whether the student remembers the English words accurately or not by analyzing the actual voice formed by the student according to the standard pronunciation audio corresponding to each word in the English word recitation list and feeds back a prompt message indicating whether the corresponding word recitation is accurate or not to the student in time, so that a semantically related English word set can be generated as the student remembering and reading list based on a vocabulary related memory mode, the student is helped to recite and memorize a large number of similar English words in a short time, the efficiency of reciting and memorizing the English words by the student is improved to the maximum extent, and the persistence and the accuracy of reciting and memorizing the English words by the student are ensured.
Preferably, in the step S1, the english word inputted by the student is analyzed, so as to determine the word attribute of the inputted english word; according to the word attributes, extracting and selecting a plurality of associated English words related to the input English words in the sense from a preset English word bank specifically comprises the following steps:
step S101, carrying out word spelling check on English words input by students so as to determine whether the input English words have spelling errors or not; if the spelling error exists, prompting the student to re-input English words until the spelling error does not exist; if the spelling error does not exist, determining whether the input English word belongs to a word of an adjective class or a word of a non-adjective class;
step S102, if the input English word is determined to belong to the words of the adjective category, a plurality of related English words with the same or similar meaning as the input English word are picked out from a preset English word bank;
step S103, if the input English word is determined to belong to a word of a non-adjective part of speech, determining a root and/or an affix corresponding to the input English word; and then, according to the root and/or the affix, selecting a plurality of related English words with the same root and/or affix as the input English words from a preset English word lexicon.
The beneficial effects of the above technical scheme are: the English words input by the students are analyzed to generate corresponding associated English words, so that the students can recite and memorize a specific English word set conveniently according to the actual needs of the students. In the process of actually inputting english words, the student cannot correctly and completely input english words due to the student himself, so that the input english words are misspelled, and the subsequent incorrect input english words cannot be recognized or the subsequent associated english words generated are actually different from the associated english words that the student intends to obtain. And whether spelling errors exist in the input English words can be quickly and accurately identified by utilizing a corresponding English word spelling check algorithm, and students can be reminded to re-input the English words under the condition that the input English words have spelling errors in time. Therefore, the input English words can be accurately spelled without worry. In addition, the input English words are divided into words belonging to the adjective category and words belonging to the non-adjective category according to whether the input English words belong to the word attributes of the adjective, so that the targeted associated expansion can be conveniently carried out according to the word attributes of the input English words, different associated English words can be expanded as much as possible according to the input English words, and the vocabulary of remembering and memorizing the English words by students is increased.
Preferably, in step S2, based on the past history of reciting english words of the student, the word that the student has completed reciting memory is removed from the associated english words, so as to generate a list of recitations of corresponding english words, which specifically includes:
step S201, acquiring past English word recitation history records of students, and acquiring the actual student recitation times of each English word contained in the English word recitation history records;
step S202, comparing the actual recitation times of the student of each English word with a preset recitation time threshold, and if the actual recitation times of the student is greater than or equal to the preset recitation time threshold, determining the corresponding English word as the word which is memorized after the student completes recitation;
step S203, comparing the word that the student has completed reciting memory with a plurality of associated english words one by one, and if a certain associated english word is the same as the word that the student has completed reciting memory, deleting the corresponding associated english word, so as to remove the word that the student has completed reciting memory from the plurality of associated english words, thereby generating a corresponding english word reciting list.
The beneficial effects of the above technical scheme are: because the multi-dimensional association relationship is presented between different English words, namely two different input English words can have the same associated English words, the respective associated English words of the two different input English words can overlap, the English words which are memorized by reciting and skillful in the past reciting memory process of the student can be accurately determined by analyzing the past English word reciting history record of the student, and the English words which are memorized by reciting are removed from the currently generated associated English words, so that the situation that the student repeatedly recits the same English words can be effectively avoided, and the efficiency of reciting the English words by the student is greatly improved.
Preferably, in the step S3, after all the english words in the english word recitation list are sorted, the standard pronunciation audio corresponding to each word in the english word recitation list is played in turn; recording the actual voice formed after the student follows the standard pronunciation audio, and after analyzing the actual voice, feeding back the reminding message whether the corresponding word recitation is correct or not to the student specifically comprises:
step S301, sorting all English words in the English word recitation list according to the sequence of the lengths of the English words from short to long;
step S302, according to the sequence, the standard pronunciation audio frequency of each word in the English word recitation list is played repeatedly for a plurality of times, and the actual voice corresponding to the standard pronunciation audio frequency is read by students after each playing is recorded;
step S303, analyzing whether the pronunciation of the actual voice obtained by each recording is correct or not, and if more than half of the actual voices in all the actual voices obtained by recording after the same word is read, feeding back a corresponding word reciting incorrect reminding message to the student; otherwise, the corresponding reminding message of correct word reciting is fed back to the student.
The beneficial effects of the above technical scheme are: according to the short-to-long sequence of the English words, all the English words in the English word reciting list are sorted, so that all the English words in the English word reciting list can be sorted easily and difficultly, and a student can recite the English words gradually and conveniently. And according to the sequence, repeating the standard pronunciation audio (which may be an electronic synthesized pronunciation related to the english word) corresponding to each word in the english word recitation list for several times, for example, when the english word recitation list contains three words, i.e., maybe, perhaps and posable, repeating the standard pronunciation audio corresponding to each of the three words, i.e., maybe, perhaps and posable, for 8 times. And then, after the standard pronunciation audio corresponding to the maybe is played every time in the 1 st to 8 th times, the practical voice corresponding to the standard pronunciation audio is collected and read by the students. And the actual voice acquired by the student after the standard pronunciation audio corresponding to the maybe each time is compared with the standard pronunciation audio, so that whether the pronunciation of the student for reading at this time is correct or not is determined. Finally, the analysis results of the actual voices of the students are integrated, and corresponding reminding messages are fed back to the students, so that the states of reciting and memorizing the English words by the students can be corrected in time, the students are reminded to accurately correct pronunciation errors of the students, and the efficiency of reciting the English words by the students is improved.
Preferably, in the step S303, whether the pronunciation of the actual voice obtained by each recording is correct or not is analyzed, and if more than half of the actual voices in all the actual voices obtained by recording after the same word is read after, a corresponding word reciting incorrect reminding message is fed back to the student; otherwise, the step of feeding back the reminding message of the correct recitation of the corresponding words to the student specifically comprises:
step S3031, establishing a standard phonetic symbol database, wherein each phonetic symbol in the standard phonetic symbol database corresponds to a positive integer value, as shown in the following formula (1),
α＝{a1：1 a2：2 … a48：48} (1)
in the above formula (1), α represents a standard phonetic symbol database which is a set containing 48 sets of element pairs, each set including one phonetic symbol aiAnd its corresponding positive integer value i;
step S3032, after the standard pronunciation audio frequency of each word is played, recording the phonetic symbols contained in the standard pronunciation audio frequency of each word; after the student follows and reads the actual voice corresponding to the standard pronunciation audio, recording the phonetic symbols contained in the actual voice, and determining whether the phonetic symbols exist in a standard phonetic symbol database; then, the coding values corresponding to the standard pronunciation audio frequency and the actual voice of each word are determined by using the following formula (2),
in the above formula (2), SiThe encoded value of the standard pronunciation audio representing the ith word,
code value a representing actual voice corresponding to jth follow-up reading ith word standard pronunciation audio of studentn iA positive integer value corresponding to the nth phonetic symbol in the standard phonetic symbol database, am i,jThe positive integer value of the mth phonetic symbol contained in the jth following read ith word standard pronunciation audio of the student in the standard phonetic symbol database is represented, if the mth phonetic symbol does not exist in the standard phonetic symbol database, am i,j＝0；
Step S3033, determining whether the pronunciation of the actual voice is correct or not by using the following formula (3),
in the above formula (3), δiA determination value indicating whether the pronunciation of the actual pronunciation of the ith word is correct or not, when deltaiWhen the number is 1, the pronunciation of more than half of all the actual voices recorded after the i-th word is read is incorrect, and when the number is deltaiWhen the number in the parentheses is greater than or equal to 0, the value of the step function is 1, and when the number in the parentheses is less than 0, the value of the step function is 0;
if more than half of the actual voices in all the recorded actual voices are incorrect aiming at the same word after being read, feeding back a corresponding reminding message that the word reciting is incorrect to the student; otherwise, the corresponding reminding message of correct word reciting is fed back to the student.
The beneficial effects of the above technical scheme are: the English pronunciation comprises a plurality of different phonetic symbols (such as vowel phonetic symbol pronunciation, consonant phonetic symbol pronunciation and the like), each phonetic symbol corresponds to a unique standard pronunciation, a corresponding standard phonetic symbol database is established by using the formula (1), and each phonetic symbol corresponds to a positive integer value uniquely, so that the English phonetic symbols can be subjected to numerical conversion, the pronunciation subjective impression of the English phonetic symbols is converted into objective numerical values, and quantitative evaluation processing can be performed on the phonetic symbols subsequently. Secondly, the actual pronunciation of the student after reading the standard pronunciation audio frequency each time has corresponding difference, these differences may be the result of the student reading incorrectly for one or several of the phonetic symbols in the word, these differences, which are usually subtle, cannot be accurately determined if the entire actual pronunciation of the word is recognized, by using the formula (2), the actual pronunciation can be decomposed into different phonetic symbols for identification processing, in practical cases, all the phonetic symbols contained in the standard pronunciation audio will exist in the standard phonetic symbol database, and the student follows the formed actual pronunciation and may have the problem of accent so that partial pronunciation phonetic symbols do not exist in the standard phonetic symbol database, thus, the above formula (2) can respectively determine the respective corresponding code values of the standard pronunciation audio and the actual speech of each word, so as to perform numerical conversion on the whole pronunciation of the standard pronunciation audio and the actual speech. Finally, using the above formula (3), the actual voices formed after each subsequent reading by the student can be quantitatively evaluated, which can more quickly and accurately determine whether the actual voices of the student are correct or not, compared to performing audio recognition on the actual voices formed each time, respectively.
