Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.
In order to explain the technical means of the present invention, the following description will be given by way of specific examples.
Referring to fig. 1, it is a flowchart of an implementation of a speech recognition method provided in an embodiment of the present invention, and the speech recognition method shown in fig. 1 may include:
s11: if the preset operation for voice recognition is detected, monitoring a comparison result of the first input voice received in the preset operation and a pre-stored first reference voice.
In step S11, the preset operation for performing voice recognition may be a trigger operation that performs voice recognition when a preset application is opened on the terminal, or a trigger operation that performs voice password input by manual triggering in the process of using the preset application, or a trigger operation that triggers the current operation interface to jump to the voice recognition interface in the step of obtaining the request for permission, where the trigger operation may be implemented by single click, double click, or continuous pressing of a trigger voice recognition button.
It should be noted that the comparison result between the first input speech and the preset first reference speech reflects whether the source of the first input speech targeted by the speech recognition is the same as the source of the first reference speech.
In this embodiment, if the source of the first input speech is the same as the source of the first reference speech, it indicates that the first reference speech can be updated according to the first input speech. If the source of the first input voice is different from that of the first reference voice, the first input voice indicates that the first reference voice cannot be updated according to the first input voice. By monitoring the comparison result of the first input voice received in the preset operation and the prestored first reference voice, whether the display interface content is consistent with the interface content corresponding to the preset operation or not can be judged by acquiring the display interface content after voice recognition, and then the comparison result of the first input voice and the prestored first reference voice is determined.
Taking the resource payment in the preset application by the user through the voice recognition as an example, the interface content corresponding to the preset operation is prompt that the resource payment is successful, and when the obtained display interface content after the voice recognition is prompt that the payment is not completed or the payment fails, it is determined that the comparison result between the first input voice and the pre-stored first reference voice is not matched. And when the obtained display interface content after the voice recognition indicates that the payment is successful, determining that the comparison result of the first input voice and the pre-stored first reference voice is matching.
In other embodiments, the comparison result between the first input voice received in the preset operation and the pre-stored first reference voice is monitored, and the comparison result between the first input voice and the pre-stored first reference voice can be determined by determining whether a new task or a new process exists or by obtaining the content of the new task or the new process.
Illustrated is voice recognition for account login.
For example, the preset operation is used for inputting a first input voice for login verification, and when the comparison result between the first input voice and a pre-stored first reference voice is a match, the corresponding login interface is loaded and displayed when the language identification is successful. And when the comparison result of the first input voice and the pre-stored first reference voice is not matched, no operation is performed. Therefore, the comparison result of the first input voice and the pre-stored first reference voice can be determined by judging whether the newly added task or the newly added process of the logged interface is loaded and displayed.
S12: and if the comparison result is that the first input voice is matched with the first reference voice, setting a mark stamp for the first input voice.
In step S12, the tag stamp is used to tag the first input speech and reflect that the source of the first input speech is legal, i.e. the source of the first input speech is the same as the source of the first reference speech.
It should be noted that the first input voice and the first reference voice each include a header protocol and a voice data content corresponding to each other, where the header protocol can be used to reflect at least a file size of the voice, a duration of the voice content, and a voice format.
In this embodiment, the setting of the mark stamp for the first input voice may be setting a marker in a header protocol corresponding to the first input voice, or setting a mark keyword in a file name of the first input voice.
As a possible implementation manner, step S12 may include: if the comparison result is that the first input voice is matched with the first reference voice and the file format of the first input voice is consistent with that of the first reference voice, setting a mark stamp for the first input voice; if the comparison result is that the first input voice is matched with the first reference voice and the file format of the first input voice is not consistent with that of the first reference voice, a voice format conversion tool is called to convert the first input voice into a target input voice with the file format consistent with that of the first reference voice, and a mark stamp is set for the target input voice.
It is understood that the voice format conversion tool may be an existing voice file format conversion tool, for example, the first input voice is in MP3 format, the first reference voice is in WAV format, and the ". MP 3" is modified to ". WAV" by calling the voice file format conversion tool to modify the suffix name of the first input voice, so that the first input voice and the first reference voice can be spliced and played.
S13: and calling a voice splicing tool to splice the first input voice with the mark stamp and the first reference voice to obtain second reference voice.
In step S13, the first input voice with the tag stamp is spliced with the first reference voice, specifically, the voice data of the first input voice with the tag stamp is spliced with the voice data of the first reference voice, and the spliced voice data is encapsulated with the new header protocol, so as to obtain the second reference voice.
It should be noted that the voice data corresponding to the second reference voice at least includes the voice data of the first input voice and the voice data of the first reference voice.
In this embodiment, the voice splicing tool is a script file for splicing the first input voice with the mark stamp and the first reference voice, wherein the object-oriented object of the script file is the voice data of the first input voice with the mark stamp and the voice data of the first reference voice.
It should be noted that voice splicing is different from voice synthesis, and voice splicing is to splice voice data in at least two voice files, and may be voice data head-to-tail splicing or voice data segmentation interception splicing, where when voice data head-to-tail splicing is performed, a start timestamp position, a splicing point timestamp position, and an end timestamp position of the spliced voice data are determined in the voice data in at least two voice files; when the voice data in at least two voice files are segmented and spliced, a plurality of voice segments to be spliced are obtained, and the plurality of voice segments to be spliced are spliced into complete voice data according to a preset voice data segment splicing strategy.
It can be understood that, in the process of calling the voice splicing tool to perform voice splicing to obtain the second reference voice, the script file corresponding to the voice splicing tool may be written by the existing logic language, that is, in actual application, the object-oriented of the voice splicing tool may also be a voice splicing process.
S14: and when the preset operation is detected again, dividing the second reference voice segment into a first segmented voice and a second segmented voice.
In step S14, the first segmented speech corresponds to the first reference speech, and the second segmented speech corresponds to the first input speech.
In this embodiment, the first segmented voice corresponds to the first reference voice, which means that the voice data corresponding to the first segmented voice is the voice data corresponding to the first reference voice, that is, the voice content of the first segmented voice is the same as the content of the first reference voice, and similarly, the second segmented voice corresponds to the first input voice, that is, the voice content of the second segmented voice is the same as the content of the first input voice.
It should be noted that, the second reference voice segment is divided into a first segmented voice and a second segmented voice, where a mark point for distinguishing the first segmented voice from the second segmented voice is set in the second reference voice segment, and a corresponding mark position is set according to the respective voice data lengths of the first reference voice and the first input voice, so as to divide the second reference voice segment into the first segmented voice and the second segmented voice.
S15: and comparing the second input voice received in the redetected preset operation with the first segmented voice by voiceprint features.
In step S15, the comparing the voiceprint features of the second input voice with the first segmented voice is performed by drawing a target voiceprint corresponding to the second input voice and a first voiceprint corresponding to the first segmented voice, extracting the voiceprint features in the target voiceprint, and then comparing the voiceprint features with the first voiceprint as a reference.
It is noted that the voiceprint can be at least one of a broadband voiceprint, a narrowband voiceprint, an amplitude voiceprint, a contour voiceprint, a time spectrum voiceprint, and a cross-sectional voiceprint, wherein the cross-sectional voiceprint comprises a cross-sectional broadband voiceprint and a cross-sectional narrowband voiceprint. The broadband voiceprint image and the narrowband voiceprint image are used for reflecting the change characteristics of the frequency and the intensity of the voice in the voice along with the time; the amplitude voiceprint image, the contour voiceprint image and the time spectrum voiceprint image are used for reflecting the characteristics of the change of the voice intensity or the voice pressure along with the time; the cross-sectional voiceprint is used for reflecting the intensity and frequency characteristics of the sound wave at a certain time point.
In all embodiments of the present invention, when voiceprint image comparison is performed between voices, the categories of the two voiceprint images that are compared are the same.
In this embodiment, the voiceprint feature comparison between the second input speech and the first segmented speech may specifically be to compare similar features in the voiceprints of the same characters and words in the second input speech and the first segmented speech. For example, the frequency values of resonance peaks in the voiceprint images of the second input voice and the first segmented voice are respectively selected for comparison, and then the same point and the different point between the second input voice and the first segmented voice are found out.
It can be understood that, in practical applications, when comparing the voiceprint features between the second input voice and the first segmented voice, and when comparing based on different voiceprint maps, the feature points used for comparison may also be different, and a specific voiceprint feature comparison scheme exists in the prior art, and therefore details are not repeated here.
S16: and if a first matching rate obtained by comparing the second input voice with the first segmented voice is smaller than a first preset matching rate, comparing the voiceprint characteristics of the second input voice with the second segmented voice.
In step S16, the first matching rate is used to reflect the comparison result between the second input speech and the first segmented speech. The first preset matching rate is used for describing the lowest matching rate standard when the comparison result of the second input voice and the first segmented voice is matched.
It should be noted that, in all embodiments of the present invention, the matching rate is used to describe the similarity degree between two voices being compared, that is, the higher the matching rate value is, the more similar the two voices being compared with the voiceprint feature are, and the greater the possibility of belonging to the same source is.
In this embodiment, the specific implementation manner of comparing the voiceprint characteristics of the second input voice with the first segmented voice is similar to that in step S15, and therefore, the detailed description is omitted here.
It is understood that in other embodiments of the present invention, the speech recognition method further comprises a first parallel step juxtaposed with step S16: and if a first matching rate obtained by comparing the second input voice with the first segmented voice is equal to or greater than a first preset matching rate, determining that the second input voice is matched with the second reference voice.
It should be noted that step S16 is not in the order of execution of the first parallel step, and the first parallel step is not executed after step S16 is executed, and step S16 is not executed after the first parallel step is executed.
S17: and if a second matching rate obtained by comparing the second input voice with the second segmented voice is equal to or greater than a second preset matching rate, determining that the second input voice is matched with the second reference voice.
In step S17, the second matching rate is used to reflect the comparison result between the second input speech and the second segmented speech. The second preset matching rate is used for describing the lowest matching rate standard when the comparison result of the second input voice and the second segmented voice is matched.
It should be noted that, in all embodiments of the present invention, the matching rate is used to describe the similarity degree between two voices being compared, that is, the higher the matching rate value is, the more similar the two voices being compared with the voiceprint feature are, and the greater the possibility of belonging to the same source is.
In this embodiment, the specific implementation manner of comparing the voiceprint characteristics of the second input voice with the second segmented voice is similar to that in step S15, and therefore, the detailed description is omitted here.
In the present embodiment, the speech recognition method further includes a second parallel step parallel to step S17: if a second matching rate obtained by comparing the second input voice with the second segmented voice is smaller than a second preset matching rate, determining that the second input voice is not matched with the second reference voice; wherein the first preset matching rate is equal to the second preset matching rate.
It should be noted that, step S17 is not in sequence with the execution of the second parallel step, and the second parallel step is not executed after step S167 is executed, and the step S17 is not executed after the second parallel step is executed.
As can be seen from the above, in the embodiment of the present invention, when a preset operation for performing voice recognition is detected, a comparison result between a first input voice received in the preset operation and a prestored first reference voice is monitored, and when the comparison result is a match, a mark stamp is set for the first input voice, and the first input voice with the mark stamp is spliced with the first reference voice by calling a voice splicing tool, so as to obtain a second reference voice; when the preset operation is detected again, the second reference voice segment is divided into the first segmented voice and the second segmented voice, the second input voice detected again is compared with the first segmented voice in a voiceprint characteristic mode to obtain a first matching rate, whether the voiceprint characteristic comparison is carried out on the second input voice and the second segmented voice or not is determined according to a comparison result of the first matching rate and the first preset matching rate, the reference voice is updated in the voice recognition process, the reference voice can change along with the natural change of the voice of the same recognized person, and the phenomenon of inaccurate voice recognition caused by the change of the voice of the person is avoided.

In step S23, the speech concatenation tool includes: a data header protocol tool and a data content splicing tool; the first input voice and the first reference voice each include a header protocol and voice data content.
As a possible implementation manner of this embodiment, step S23 may specifically include: calling the data header protocol tool to respectively split the first input voice and the first reference voice to obtain a first data header protocol and first voice data content corresponding to the first input voice and a second data header protocol and second voice data content corresponding to the second input voice; generating a new data header protocol according to the first data header protocol and the second data header protocol; calling the data content splicing tool to splice the first voice data content and the second voice data content to obtain new voice data content; and encapsulating the new data header protocol and the new voice data content to obtain the second reference voice.
In this embodiment, the header protocol tool may be a preset wavheader.h script, and the first header protocol and the first voice data content, and the second header protocol and the second voice data content are obtained by executing the content in the script for parsing the header protocol.
In the WavHeader.h script, the number of digits of each parameter in a voice data header protocol and the number of digits occupied by voice data content are defined and distinguished, and the first input voice and the first reference voice are split by operating the WavHeader.h script to obtain a first data header protocol and first voice data content corresponding to the first input voice and a second data header protocol and second voice data content corresponding to the second input voice.
In this embodiment, the first header protocol and the second header protocol are respectively used to describe the voice duration, the voice size, and other contents of the first input voice and the first reference voice. And the voice time described by the new data header protocol generated according to the first data header protocol and the second data header protocol is the sum of the first input voice time and the first reference voice time, and the voice size described by the new data header protocol is the sum of the first input voice size and the first reference voice size.
The data content splicing tool may include a voice data reading tool DataRead and a voice data writing tool DataWriter.
It should be noted that both the voice data reading tool DataRead and the voice data writing tool DataWriter can be packaged and read via corresponding binary data streams.
In this embodiment, a new header protocol and new voice data content are encapsulated to obtain a second reference voice, where various voice data parameters in the new header protocol correspond to the new voice data content, that is, voice duration information and voice size information in the new header protocol are consistent with the duration and size of the voice data content.

In step S28, InN and N are integers, N is not less than 1, and N is more than 1.
In this embodiment, the result of matching the second input speech with the second reference speech only occurs once during each speech recognition process. When the voice recognition is carried out for N times and each voice recognition result is the result of the matching of the second input voice and the second reference voice, the counting value in the counter is set as In.

When I isnWhen the matching threshold value is equal to the preset matching threshold value N, the fact that the second input voice is matched with the second reference voice is an event is an inevitable event, namely the possibility that the event that the second input voice is matched with the second reference voice is an accidental event is eliminated。
In practical applications, the preset matching threshold may be determined according to a period of a change of the voice, or according to a number of times that the second reference voice is compared with the most comparative standard, or according to a duration of use of the second reference voice.
It should be noted that, a marking stamp is set for the second input speech, and the marking stamp is used for marking the second input speech and reflecting that the source of the second input speech is legal, that is, the source of the second input speech is the same as the source of the second reference speech.
