How to Manually Deploy NextGen Voice Biometric Engine

Patch MAP

Make sure you have the latest version of MAP up and running. To do so, copy the following files located in the directory: 

note

X:\LumenVox7\Internal\Selene\Assure KB1 to your VTAssure System Directory.

Engine

Manually copy the following files:

X:\LumenVox7\Internal\Selene\Framework\bin  

The sources are available as a Nuget Package on our Nugget Server.  'http://rs-bs01.dev.voicetrust.de:1860/LVNugGetServer/nuget

They are also available as built artifact located on our build server : http://golem.dev.voicetrust.de:8080/tfs/Lumenvox/V7/_build?_a=completed&definitionId=2 (use tfs credentials to authenticate) and download the zip. Location of files within zip is : drop\Framework\bin\Release\netstandard2.0

Resources 

• Resource files are located  under : X:\LumenVox7\Internal\Selene\Resource

Copy 

• Copy the Engine libs to the <assure system> folder (ie. C:\LumenVox\Assure\System) 

• Copy the resources to <assure system>\Selene\Resources ( should not have duplicate resouces). There are two models currently, please use resources.201906271.dat as default. Folder should contain single file called  : resources.201906271.dat  (ie. C:\LumenVox\Assure\System\\Selene\Resources\resources.201906271.dat) 

Configuration

Navigate to the MAP manager, location should specified in the LumenVoxAssureSummary.txt file under Q:\LumenVox\Assure\

Verifier

• Navigate to Management ?Verifier ?Verifiers 

• Click “New Verifier.”
  

  

  
  
  

•  Create a new “text-independent” verifier with: VoiceTrust.VoiceBiometrics.Selene.v10.VTSelene,Biometrics.Selene.v1.0
  

  

• Navigate to Verifier ? Parameters 

• Click “Create New Parameter.”

• Create the following parameter with the following values :

• Name : VTRootPath
  Validatation: ^(?:[a-zA-Z]\:|\\\\[\w\.]+\\[\w\.\-$]+)\\(?:[\w.-]+\\)*\w([\w.-]*)+$
  Description : Path to the Selene resource base directory.
  Grouping:1100
  

• Select "Verifier Type" and "Type" from the drop-down menu. 

  

• Navigate back to Verifier?Verifiers and assign resource path of VTRootPath parameter to the files copied in the first step:
  VTRootPath : C:\LumenVox\Assure\System\Selene\Resources\resources.201906271.dat
  
  

Enrollment Profile

• Navigate to Profile ?Profiles.

• Select "New Profile."
  
  

• Create the profile naming, making sure:
  Verifier: Drop down should have the new NextGen Voice Biometric Engine Verifier selected.
  Status :  Enabled.
  

  

• Navigate to Profile Parameters and create the following two Parameters (simillar to the verifier parameter creation) :
  
  Name: SampleType
  Verifier Type : Text Independent.
  Type: Drop down
  Validation :(X|A|U)
  Information :{"X": "PCM16","U":"uLaw","A":"aLaw"}
  Description :Sample Type coming into Assure.
  
  Name: RequiredSpeechLength
  Verifier Type : Text In dependant.
  Type: Uint
  Validation :^([4-9]|[1-5][0-9]|60)$
  Description: The length of audio ( without silence) that needs to be processed before vtassure considers the enrollment complete.
  

• Navigate to “Create Profile,” and set the SampleType parameters according to your incoming audio and the RequiredSpeechLength to 20 .

Configuration Profile

• Repeat the activity performed for the Enrollment Profile to create the configuration profile.

• Use following Configuration Parameters:

Name: SampleTypeVerifier Type : Text Independent.Type: Drop downValidation :(X|A|U)Information :{"X": "PCM16","U":"uLaw","A":"aLaw"}Name: AcceptThresholdVectorVerifier Type : Text Independent.Type: StringValidation :.*Description:Accept score vector.Name: RejectThresholdVectorVerifier Type : Text In dependant.Type: StringValidation :.*Description:Reject score vector.Name: CompletionThresholdVerifier Type : Text Independent.Type: floatValidation: ^(?=.+)(?:[1-9]\d*|0)?(?:\.\d+)?$Description: The completion threhold

• Set the parameters to the following values.
  
  AcceptThresholdVector : {"5.0":0.9,"10.0":0.8,"15.0":0.75,"20.0":0.7}
  RejectThresholdVector: {"5.0":0.1,"10.0":0.2,"15.0":0.3,"20.0":0.45}
  CompletionThreshold: 0.65
  SampleType: Should match the expected incoming audio.

Updating Logging

To enable NextGen Voice Biometric logging, add the following line to the VTassure.exe.nlog file in the MAP system directory.

<logger name="Selene" minlevel="Trace" writeTo="file" />

Database Script

Run the following database script.

INSERT INTO dbo.RESULT_DEFINITION(RESULT_TYPE,RESULT_DESCRIPTION,RESULT_NAME,RESULT_ORDER)VALUES('u','Current Audio Gross Length','Gross Audio Sample Length',1)INSERT INTO dbo.RESULT_DEFINITION(RESULT_TYPE,RESULT_DESCRIPTION,RESULT_NAME,RESULT_ORDER)VALUES('v','Required Audio Length','Required Audio Length',2)INSERT INTO dbo.RESULT_DEFINITION(RESULT_TYPE,RESULT_DESCRIPTION,RESULT_NAME,RESULT_ORDER)VALUES('x','Evaluation Point','Evaluation Point',3)GO
