Fig. 1 is a kind of implementation process schematic diagram of the comparison method for voice messaging that one embodiment of the invention provides, such as
This method may comprise steps of shown in figure：
Step S101, two voice messagings to be compared are obtained, by sound corresponding to every voice messaging generation to be compared
Frequency oscillogram.
In embodiments of the present invention, two voice messagings to be compared are obtained first, and one of voice messaging can be made
For received pronunciation information, another voice messaging, which can be used as, compares voice messaging, wherein the received pronunciation information is as base
Standard, by compare voice messaging be compared with received pronunciation information, obtain comparison voice messaging whether with received pronunciation information
Voice content is consistent.Because voice messaging can generally switch to text information, it is possible to be converted to two voice messagings
Text information, then compare the text information in two voice messagings, it is possible to which obtaining the voice content of two voice messagings is
It is no consistent, but during being converted into text information due to voice messaging, it is pair of element according to voice messaging and word
It should be related to, voice messaging is mapped as text information, the pronunciation or linguistic context due to many text informations are different, are actually turning
Deviation is likely to occur during change, so by the way that voice messaging to be compared is converted into the method being compared again after word simultaneously
Precise alignment can not be accomplished.The embodiment of the present invention passes through first by audio volume control figure, sound corresponding to voice messaging generation to be compared
The information such as the loudness, tone color, frequency of audio are contained in frequency oscillogram, can more represent voice messaging.
Specifically, audio volume control figure corresponding to every voice messaging generation to be compared is included：
The voice messaging is decompressed, and the voice messaging is randomly divided into multiple data blocks；
The amplitude of sampled point and the sampled point is obtained according to default sample mode in each data block；
Sampled point is ranked up according to the time audio volume control figure is generated according to the amplitude of each sampled point afterwards.
In embodiments of the present invention, during voice messaging is generated into audio volume control figure, can be obtained according to the time
Sampled point, the data for only choosing sampled point generate audio oscillogram, can so reduce amount of calculation, we can first decompress
The voice messaging, the voice messaging after decompression being randomly divided into multiple data blocks, the size of each data block is not fixed,
Then sampled point is obtained according to default sample mode in each data block, because the data block divided in advance is according to random
Mode divides, and is sampled in each data block according to fixed mode, so, this existing randomness has rule again
The sampled point that the sample mode of rule property to obtain can more represent voice messaging sample, after obtaining the sampled point of each data block,
Also sampled point is ranked up according to the time in voice messaging, so equivalent in voice messaging sample according to both wrapping
Contain random, the sample mode for containing regularity again is sampled, and after obtaining sampled point, then obtains number corresponding to sampled point
According to, such as amplitude, generate audio volume control figure.
Step S102, audio volume control figure corresponding to two voice messagings is compared, obtain two voice messagings
Similarity.
In embodiments of the present invention, the letter such as loudness, tone color, frequency of one section of voice messaging is contained in audio volume control figure
Breath, for example, in audio volume control figure, upper and lower amplitude representative loudness, the combination of frequency represent tone color, and period distances represent
Frequency.We can obtain the similarity of two voice messagings by the way that the audio volume control figure of two voice messagings is compared.
Such as two audio volume control figures can be carried out overlapping Comparison Method, the part generation overlapped in the audio volume control figure of two voice messagings
The consistent part of table, the part that can not be overlapped represent inconsistent part, and the hundred of total oscillogram can be accounted for according to the part of coincidence
Be divided to the similarity for being used for two audio volume control figures, the similarities of two audio volume control figures namely two voice messagings it is similar
Degree.
Step S103, if the similarity of two voice messagings is more than threshold value, export two voice messagings
Voice content identical comparison result；If the similarity of two voice messagings is less than or equal to the threshold value, institute is exported
State the comparison result that the content of two voice messagings differs.
In embodiments of the present invention, due to before the similarity of two voice messagings to be compared is obtained, it is possible to pass through
Format conversion, the generation process such as oscillogram are crossed, even so the information of two voice contents of identical, in the mistake of format conversion
Two audio volume control figures that encoding variability between different-format causes to ultimately generate are also possible in journey can't be completely the same, or
Person is different due to the method sampled during generation audio volume control figure, it is also possible to which two audio volume control figures for causing to ultimately generate will not
It is completely the same.At this moment we just need to set threshold value, when the similarity of two voice messagings is more than threshold value, then show two languages
The voice content of message breath is consistent, it is possible to the voice content identical sound result of two voice messagings is exported, otherwise,
Export the comparison result that the content of two voice messagings differs.
The mode of the default sampling can be according to fixed step size carry out sampling, can also be according to it is existing its
Its sample mode is sampled, and will not be repeated here.
Then the embodiment of the present invention is compared by the way that two voice messagings to be compared are generated into corresponding audio volume control figure respectively
The similarity of two voice messagings is obtained to the audio volume control figure of two voice messagings, two voice messagings are judged by similarity
Content it is whether consistent.
Fig. 2 is a kind of implementation process schematic diagram of the comparison method for voice messaging that further embodiment of this invention provides, such as
This method may comprise steps of shown in figure：
Step S201, two voice messagings to be compared are obtained, two voice messagings to be compared are set respectively
For received pronunciation information and compare voice messaging.
Step S202, obtains the data format of the received pronunciation information, and by the data lattice of the comparison voice messaging
Formula is converted to the data format of the received pronunciation information.
In embodiments of the present invention, due to needing to generate audio volume control figure, the coded system of the audio file of different-format
Difference, may can slightly have gap when generating audio volume control figure, so we are after two voice messagings to be compared are obtained,
First identify whether the data format of two voice messagings to be compared is identical, if differing, by two languages to be compared
Message breath is converted to identical data format, can be converted into predetermined audio format simultaneously, can also be by one of voice
Information is converted into the voice document with another voice messaging identical data format, can specifically obtain the standard speech message
The data format of breath, the Data Format Transform by the comparison voice messaging are the data format of the received pronunciation information.Language
The data format of message breath i.e. the form of audio, can there is MP3, WAV, AU, SND, RAW, AFC etc..
Step S203, identify the mute part in every voice messaging, and the Jing Yin portion in the voice messaging that will identify that
Cutting removes.

Step S204, by audio volume control figure corresponding to every voice messaging generation to be compared.
The step is identical with step S102, specifically can refer to step S102 explanation, will not be repeated here.
Step S205, dot matrix image is generated according to audio volume control figure corresponding to every voice messaging, compared by dot matrix
Method compares dot matrix image corresponding to two voice messagings, obtains the similarity of two voice messagings.
In embodiments of the present invention, audio volume control figure can also be generated dot matrix image, dot matrix image is also dot chart, point
The least unit of the system of battle formations is pixel, and dot chart is exactly the figure that display effect is realized by the arrangement of pel array.Generate dot matrix image
Afterwards, we can compare dot matrix image corresponding to the voice messaging by the method that dot matrix compares, so, equivalent to each
Dot matrix image corresponding to voice messaging can be all made up of several pixels, and we realize ratio by comparing pixel one by one
To two voice messagings, the ratio acquisition that the number of total pixel can be so accounted for by the number of identical pixel is similar
Degree.
Step S206, if the similarity of two voice messagings is more than threshold value, export two voice messagings
Voice content identical comparison result；
If the similarity of two voice messagings is less than or equal to the threshold value, two voice messagings are exported
The comparison result that content differs, and change the comparison voice messaging and cause the comparison voice messaging and the received pronunciation
The data content of information is consistent or according to the data format for comparing voice messaging, by the data of the received pronunciation information
Form is converted to the data format for comparing voice messaging to replace the comparison voice messaging.
In embodiments of the present invention, if the similarity of two voice messagings is less than threshold value, then explanation compares voice messaging
Voice content relative to received pronunciation information is inconsistent, at this moment needs two voice messagings being revised as in identical voice
Hold, can will compare voice messaging and be revised as the voice messaging consistent with the data content of received pronunciation information, can also delete
Fall and compare voice messaging, as comparison voice letter after received pronunciation information directly is converted into the data format for comparing voice messaging
Breath, such received pronunciation information are exactly consistent with the voice content of comparison voice messaging.
The embodiment of the present invention is changed by entering row format to the voice messaging to be compared of acquisition, excision mute part, generation
Oscillogram and then dot chart is generated according to oscillogram, compare dot chart and be obtained with the similarities of two voice messagings, so
Than pair mode can more accurately obtain the similarities of two voices to be compared.
