Description
Technical Field
The present invention relates to the field of speech recognition technologies, and in particular, to a method and an apparatus for repairing a speech recognition single number, an electronic device, and a storage medium.
Background
With the continuous development of speech recognition technology, more and more application scenes of speech interaction and man-machine conversation appear. For example, many applications require a user to provide information similar to a single number, such as an order number, a license plate number, an identification number, a bank card number, etc., which can be provided by the user as a voice input in a voice interaction scenario in order to facilitate the user to provide the information.
More and more service scenes need to identify the single number information input by the user in a voice form, but the single number information is usually long letter and number string information, and because the length of the information is long, the user cannot complete and accurately speak at one time when inputting voice, and because the voice recognition may generate errors, the final recognition result may be inaccurate.
In order to solve the problem that the single number information is long and cannot accurately pass through voice recognition, the current solution is that after the single number information is recognized through a voice recognition technology, a user confirms the single number, and when a recognition error is found, the user actively modifies the single number information to correct the error information in the recognized single number information. However, this way of active modification by the user increases the number of interactions between the user and the application and system, reduces the user experience, and may introduce new errors due to the speech recognition errors that may be brought by the speech recognition technology.

As shown in fig. 1A, an embodiment of the present invention provides a method for repairing a speech recognition single number, which is applied to a terminal device, and the method includes:
s11, the terminal equipment acquires a voice signal and performs voice recognition on the voice signal to obtain a recognition single number;
s12, the terminal device records the identification single number into a database, judges whether the identification single number is a first input single number or not, and if yes, enters S13; if not, the process goes to S14;
s13, the terminal equipment executes first single number repair to generate one or more repair single numbers, and the step enters S17;
s14, the terminal equipment judges whether to execute user repair, if so, the process goes to S15; if not, the process goes to S16;
s15, the terminal equipment executes user repair;
s16, the terminal equipment executes automatic repair to generate one or more repair single numbers, wherein the automatic repair comprises at least one of similarity repair, splicing repair, de-duplication repair and error-prone character repair;
s17, the terminal equipment determines whether a correct single number exists in the one or more repair single numbers based on the verification result of the single number system, and if so, the correct single number is recorded; if not, the process proceeds to S14.
The S11, the terminal device obtains a voice signal, and carries out voice recognition on the voice signal to obtain a recognition single number;
the terminal device can be any intelligent terminal or electronic device such as a smart phone, a tablet computer and a PC.
In the embodiment, the single number in the user voice signal is recognized through ASR.
In this embodiment, the length of the single sign in the user speech signal conforms to the normal distribution. For example, if the correct single number is 10 digits, the highest one of the identified single numbers is the 10 digit single number, and the second is the 9 and 11 digits, which are sequentially decreased. For another example, if the number of digits of the single number is correct, if the identified single number has an error, the ratio of digits with one bit error is the largest, and so on.
S12, the terminal device records the identification single number into a database, judges whether the identification single number is a first input single number or not, and if yes, enters S13; if not, the process proceeds to S14,
the terminal device records the identification single number into a database, and judges whether the identification single number is a first input single number, and the method comprises the following steps:
the terminal equipment records the identification single number and the user voice instruction identification ID into the database, inquires the database according to the user voice instruction identification ID, determines whether the identification single number has the single number, and determines that the identification single number is the first input single number if the identification single number does not have the single number; otherwise, the identification single number is not the first input single number; the above single number is a unique single number obtained by searching through the user voice instruction identification ID.
S13, the terminal equipment executes first single number repair to generate one or more repair single numbers, and the step enters S17;
wherein, the first single number repair comprises duplication removal repair and error-prone character repair;
the duplicate removal and repair is that if the number of the character digits of the identification single number and/or the repair single number exceeds the correct number, the terminal equipment searches for the repeated sub-character strings in the identification single number and/or the repair single number, and if the number of the character strings obtained by deleting the repeated sub-character strings in the identification single number and/or the repair single number is the correct number, the repeated sub-character strings in the identification single number and/or the repair single number are deleted, so that one or more repair single numbers are obtained.
Deduplication fixes addresses the situation where the user has duplicate readings while saying a single number. For example, the correct single number to be input by the user is "1234567890", the voice input by the user is "single number is 123, 1234567890", it is determined that the number digit number of the single number exceeds the correct number of digits by 10 for the recognized single number "1231234567890", and the repeated sub-number string "123" exists in the single number, and the repeated sub-number string "123" is deleted, so as to obtain the repaired single number "1234567890".
And the repeated repairing also comprises deleting the corresponding repeated sub-digit strings if the repeated sub-digit strings exist at a plurality of positions and the digit number of the obtained digit string is the correct digit number after the repeated sub-digit strings are respectively deleted.
The error-prone character repairing is to store the identification single number and/or the repair single number by the terminal equipment, count and determine characters which are easy to confuse and lose according to historical data, and replace the characters which are easy to confuse in the identification single number and/or the repair single number; supplementing characters which are easy to lose to the identification single number and/or the repair single number with insufficient digits; and generating a new repair order number, and taking the new repair order number and the pre-stored identification order number and/or repair order number as target repair order numbers so as to obtain one or more repair order numbers.
And if the identification single number is not changed after the duplication removal repair and the error-prone character repair, taking the identification single number as a repair single number.
In another embodiment, for example, according to the historical data, it is counted that the ratio of confusion of 3 and 4 exceeds the threshold, and it is counted that the ratio of missing numbers 2 and 5 exceeds the threshold, then 3 and 4 are determined to be confusable numbers; 2 and 5 are determined as easy-missing numbers. And replacing the confusable number 3 in the single number and/or the repair single number with the number 4, replacing the number 4 with the number 3, and identifying all the confusable numbers in the single number and/or the repair single number by replacing part or all the confusable numbers in the single number and/or the repair single number by replacing the operation.
The S14, the terminal equipment judges whether to execute user repair, if yes, the S15 is entered; if not, the process proceeds to S16,
the terminal equipment receives user operation, judges whether to execute user repair according to the user operation, and executes the user repair if the user repair needs to be executed; otherwise, the terminal equipment executes automatic repair.
The S15, the terminal device performs user repair,
the user repairing is that the terminal equipment receives an active modification instruction of a user and modifies the active modification instruction in a local modification or full modification mode, wherein the local modification is that the expression of the user is received to modify a single character position until all characters which the user wants to modify are modified, and the modified single number is used as a repairing single number; and the total modification is to receive the voice signal of the whole single number re-input by the user, recognize the voice signal to obtain a new identification single number, and reset and cover the stored identification single number in the database by using the new identification single number as a repair single number.
And only one repair single number is generated in the local modification mode and the whole modification mode.
S16, the terminal device executes automatic repair to generate one or more repair single numbers, the automatic repair includes at least one of similarity repair, splicing repair, de-duplication repair and error-prone character repair,
wherein, the similarity refers to the number of the same numbers at the same positions of two single numbers;
the similarity restoration includes:
determining the correct number n of the single number, selecting the identification single number and/or the repair single number with the character number between [ n-1, n +1] as a single number set, and selecting a single number from the single number set as the current single number; the repairing objects of the similarity repairing of the terminal equipment are the current single number and the previous single number of the single number, and one or more repairing single numbers are generated according to a repairing strategy; until all the single numbers in the single number set and the corresponding single numbers above are repaired according to a repair strategy, wherein n is more than 1; the repair strategy comprises:
a first repair strategy is as follows: if the current sheet number and the previous sheet number of the sheet number are both n bits,
s101, comparing characters of each character position in the current single number and the previous single number of the single number, and determining all character position sets with different characters;
s102, randomly selecting a character bit with different characters from all the character bit sets, replacing the character of the corresponding character bit in the current single number with the character of the character bit corresponding to the single number above the single number, generating and recording a process repairing single number, and deleting the character bit from all the character bit sets;
s103, if the whole character bit set is not empty, entering S102; otherwise, entering S104;
s104, obtaining a repair order number;
and (2) repairing strategy two: if the current single number is n bits, the previous single number of the current single number is n +1 bits,
s201, marking the above single number of the current single number from left to right as 1 to n +1 bits, and setting i to be 1;
s202, deleting the ith bit of the previous single number of the current single number, generating a process repair single number, and calculating the similarity between the process repair single number and the current single number;
s203, if i is less than n +1, setting i as i +1, and entering S202; otherwise, entering S204;
s204, recording the process repair single number with the maximum similarity as the single number with the maximum similarity;
s205, repeating the first repair strategy for the single number with the maximum similarity and the current single number, wherein when the first repair strategy is repeated, the single number with the maximum similarity serves as the single number above, and the first repair strategy is executed with the current single number;
and (3) repairing strategy III: if the current single number is n-1 bits, the previous single number of the current single number is n bits,
s301, adding a placeholder at a certain position of the current single number to obtain a process repair single number, and calculating the similarity of the process repair single number and the previous single number of the current single number;
s302, repeating the step S301 until the obtained process with the maximum similarity restores the single number, wherein the position of the placeholder is the position of the missing character position;
and S303, replacing the corresponding placeholder with the character corresponding to the position of the missing character position and the previous single number of the current single number to obtain the repair single number.
In this embodiment, the similarity repair also supports repairing more cases and supports other repair strategies. For example, the above single numbers are n-1, n, and n +1 bits respectively, and the current single numbers are n-1, n, and n +1 bits respectively, which can generate 9 combinations, and the similarity repairing method is similar and will not be described herein again.
The following examples illustrate the repair of similarity repair:
assuming the correct single sign is a 10-digit number: 1234567890. next, several examples will be given to explain the similarity restoration method in detail.
Example 1:
the above sheet number: 1233567890
Current single number: 1234567891
The single number is 1233567890 above, where bit 4, misidentifies 4 as 3, the single number is misidentified, thus requiring the user to re-provide the single number. The current sheet number is obtained as 1234567891, and the last bit identifies an error. Since the current number is 10, it is likely to be the correct number, and therefore a list of repair numbers is added. And calculating the similarity of the above single number and the current single number to be 8, which indicates that the two single numbers are possibly staggered by one bit respectively, and if the two staggered positions are different, the terminal equipment can spell the correct single number. Therefore, the positions of the two single numbers which are different are found, the number of the current single number is replaced by the number of the last single number, and then two new single numbers are obtained: 1233567891, 1234567890. Thus, the list of final repair sheet numbers is: 1234567891, 1233567891, 1234567890. It can be seen that although the single number spoken by the user has errors in both times, the correct result is included in the list of repaired single numbers.
Example 2:
the above sheet number: 12345678990
Current single number: 1244567890
The above single sign is 12345678990 with one more digit, 9 more than the correct single sign. The current single number is 1244567890, misidentifying 3 as 4 in bit 3 as compared to the correct single number. As above, the current single number is 10 in length and therefore is likely to be the correct single number, which the terminal device adds to the list of repair single numbers. Since the above single sign is 11 bits, there is a high probability that there is one more bit. Deleting one digit of the document number respectively, and then calculating the similarity together with the second round of document numbers, it can be found that when deleting 9, the similarity is the highest, and the document number after the deleting operation is 1234567890. Then comparing the current single number with the repair single number and replacing different numbers, the single number 1234567890 can be obtained. The list of repair order numbers may be restored with 1244567890, 1234567890, including the correct result.
Example 3:
the above sheet number: 1233567890
Current single number: 123456789
The current single sign is 9 bits, and one bit is less, so the terminal equipment is respectively filled with the number at different positions to complement 10 bits, and then the similarity is calculated. And (4) replacing the filling position with the highest similarity, namely the correct filling position, with the number corresponding to the position of the above single sign to obtain a repair single sign 1234567890 which is also the correct single sign.
And splicing and repairing, if the character digit of the identification single number and/or the repair single number is lower than the correct digit, and the sum of the character digit of the identification single number and/or the repair single number and the digit of the above single number is the correct digit, splicing the identification single number and/or the repair single number to the above single number to obtain the repair single number.
For example, when a user inputs speech, a pause or a wrong interruption may occur, for example, if 4 bits are input for the first time and 6 bits are input for the second time, the two results may be spliced to obtain a repair single number.
The deduplication restoring and error-prone character restoring are the same as those in S13, and are not described herein again.
In this embodiment, the user repair is active repair of the user, so that the user performs partial modification or complete modification on the single number. The automatic repair is to obtain one or more repair single numbers according to the identified identification single number and/or the repair single number and the above information of the identification single number by a repair method such as similarity repair, and the correct single number may exist in the repair single numbers. Because the user repair can also introduce new identification errors, the automatic repair is executed after the user repair, and the accuracy of the single number repair can be improved. Therefore, the interaction times with the user are reduced, and the user experience is improved.
S17, the terminal equipment determines whether a correct single number exists in the one or more repair single numbers based on the verification result of the single number system, and if so, the correct single number is recorded; if not, go to S14;
the single number system can verify the repaired single number, judge whether the single number is correct or not, and obtain the correct single number through the verification of the single number system. The single number system can be a third-party system, for example, when the single number is an express single number, the single number system is an express single number system of an express company.
As yet another example, the repair of the speech recognition ticket number may be performed in the manner shown in FIG. 1B.
