Voice Biometrics Integration with NICE CXone

Overview

This document provides an overview of what’s required to successfully install agent-side enrollment for Voice Biometrics with NICE CXone Studio.

Voice Biometrics (VB) is used to detect and verify a caller’s identity that has been authenticated in a past call and enrolled in the VB service.

The basic steps for VB are the following:

• VB enrolment. Authoritatively assign a set of identifiers to a stored voice recording.

• VB verification. Comparing the active voice stream against stored voiceprints.

• VB verification system expectations. Speaker verification systems calculate the similarity score between two or more voiceprints from the same speaker. They differ from speaker identification systems, where the goal is to identify who is speaking amongst a set of speakers.

Prerequisites

To integrate Voice Biometrics with Nice CXone Studio you must first have completed the following tasks:

1. Create a VB profile.

2. Integrate NICE API with OCP miniApps®.

3. Arrange a free call number available in NICE.

A telephone number must be available to avoid using the same one for miniApps.

4. Generate a token through the Token Service.

Create NICE CXone script

The VB integration process mainly concerns the creation of a call script. This script will collect the information from the caller and transfer this information to an agent to complete the enrollment of customers to Voice Biometrics.

To create a new script log in NICE CXone Studio, follow the steps below:

1. Create a new script file.

2. Select a General Purpose Script for Phone application.

3. Create a script as per the below diagram.

The details of each script element with its properties are described below.

Logcall

The role of this element is to record and log the call.

Assign VB Values

Based on the call data, specific Voice Biometrics values are assigned to the caller.

The vbProfile is set along the rest properties.

The ID of the vbProfile is retrieved from the VB tab of OCP Console.

Properties

ASSIGN vbProfile="profile_retrieved_by_ocp_console"
ASSIGN middlewareUrl="https://baseurl/agent-vb-mw"
ASSIGN middlewareToken="token_retrieved_by_ocp_console"

DYNAMIC SessionRequest
ASSIGN SessionRequest.tenantId="{busno}"
ASSIGN SessionRequest.masterId="{masterId}"
ASSIGN SessionRequest.agentId="{agentId}"
ASSIGN SessionRequest.vbProfile="{vbProfile}"
ASSIGN SessionRequest.agentSkill="{sklname}"

DYNAMIC Headers
ASSIGN Headers.Authorization="Bearer {middlewareToken}"
ASSIGN Headers.Content_Type="application/json"

ASSIGN headersJson="{Headers.asjson()}"
ASSIGN headersJson = "{headersJson.replace("Content_Type", "Content-Type")}"

Request Session Token

The session creates a token that will later be posted and assigned before sent as information to the agent.

If the token creation fails for any reason a notification will be sent directly to the agent’s screen.

Assign Session Token

Upon successful session token creation, the session token is assigned with the call details and then sent to the agent.

Properties

ASSIGN token=”{result.data.token}”

Pop up Omilia iframe

A window pops up on the Agent’s screen with the details of the call.

Onrelease

This process starts when the call closes. Either because of agent transfer or call end.
