Description
Technical field
The invention belongs to law big data processing technology fields, and in particular to a kind of case wisdom auditing system.
Background technology
With the continuous development of information technology, justice system also proposed increasingly higher demands to automated process.Method
All kinds of case information of institute's trial have been enough to form the pending data in big data meaning.Through retrieval, in the prior art Shen
Number please providing a kind of criminal case for CN201710426297.1, intelligently auxiliary is handled a case method, suitable for public security subsystem, inspection
It examines subsystem and law court's subsystem provides auxiliary of handling a case, the public security subsystem, procuratorial work subsystem and method subsystem are equal
With server communication, include the following steps：
Step 21, public security subsystem to one or more of the case instrument of evidence carry out evidence collection, typing and
Verification；
Step 22, public security subsystem obtains the pending request instruction of input, and is judged according to the check results of the instrument of evidence
Whether the requirement that proposes pending request is met, if so, sending out pending request to procuratorial work subsystem by server；
Step 23, procuratorial work subsystem obtains the instrument of evidence and its check results of the public security subsystem to the case；
Step 24, procuratorial work subsystem carries out chain of evidence examination to the instrument of evidence of the case；
Step 25, procuratorial work subsystem obtains the examination result that sends out inputted and instructs, and according to the chain of evidence of the instrument of evidence
Examination result judges whether to meet the requirement for sending out examination result, if so, by server to public security subsystem or method courtyard
System sends out examination result.
However, existing case big data processing system still needs the related information retrieval capability of internet information
It improves.In the prior art, more and more sound and perfect with the law of country, the legal consciousness of people increasingly improves, judicial
The quantity of class case is also more and more.And people are when handling a case, also habitually go to search relevant case into
Row reference, so that the case point involved by case itself and relevant law are more known and understood.However, existing case is looked into
For asking or retrieving, people are generally widely to be inquired by universal search engine, and the inquiry of this inquiry mode is accurate
True rate generally requires people and carries out just inquiring useful reference case after largely screening than relatively low.In addition, people can be with
It is inquired or is retrieved by the dedicated system of judicial department, the universal search engine and this dedicated query mode compares
It says, accuracy rate increases, but it is either in formality or in mode of operation, all comparatively laborious, can not spirit
Living is suitable for civil retrieved, also, conventional judicial class case is retrieved, and is also commonly based on the full-text search of keyword
System is realized, and this retrieval can only directly retrieve related keyword whether occur, in accuracy rate also than relatively low.
Invention content
In order to improve the automatization level of justice system case examination, the present invention provides a kind of case wisdom to examine system
System, including：
Database, for storing and the relevant document information of case；
Information acquisition unit, for acquiring the voice messaging at case trial scene；
Document selection unit, for choosing document according to the voice messaging；
Document markup unit, for marking the document according to the voice messaging；
Hearing process confirmation unit confirms document for generating hearing process according to the voice messaging.
Further, described information collecting unit is multichannel voice collecting unit.
Further, the multichannel voice collecting unit is set more including speech signal analysis unit and distribution
A microphone.
Further, the document selection unit includes document title determination unit, for generating text according to voice messaging
Word, and document is chosen from the database according to the corresponding document title of word.
Further, the document markup unit is used to the word being added to the document.
Further, the database is relevant database.
Further, the hearing process confirmation unit includes：
Document establishes unit, confirms document for establishing hearing process；
Content generation unit confirms document for the document and the word to be added to the hearing process.
Further, the document title determination unit includes：
S (w) be speech signal energy spectral density function, cnFor cepstrum coefficient, pass through cnCan obtain cepstrum distance l is：
N is microphone number, and d is poor relative to the criterion distance of trial judge position for each microphone position, and wherein N (n) is institute
State the noise signal in voice messaging, S (n) is the voice signal for removing the voice messaging after noise；pi(k) be based on cepstrum away from
From speech frequency component,
Short-time average energies of the voice signal x (n) of microphone n at the n moment be：
For Hamming window functions；
To the p of each microphone compositioni(k) matrix, the matrix and E are formednCharacteristic value be multiplied, acquire covariance matrix G；
Technical scheme of the present invention has the following advantages：
The case wisdom auditing system of the live noise of trial can farthest be reduced by realizing, and pass through the system, energy
Enough noises being converted into voice during word are effectively reduced, according to test, the models such as HMM compared with the prior art
Its identification validity of voice-character recognition technology is higher by more than 70%, therefore be highly suitable for any place other than court
It carries out providing stable and reliable text conversion during case trial, greatly improve in trial efficiency.
