Solutions /Telephone Voice Verification

Add an identity check during the call.

Use existing calls for identity verification. Compare captured speech with registered voiceprints to assist call center identity checks, while managing speech, models, and call records centrally.

Comparing telephone speech with voiceprint models in real time for identity verification

Product features

From audio capture
to in-call identity comparison.

Call audio capture

Capture call audio through SIP and an external capture module for modeling and comparison.

Customer voiceprint modeling

Build voiceprint models from captured speech and store them for verification in subsequent calls.

In-call voiceprint comparison

Compare current call audio with registered models and provide recognition results during the conversation.

Call and model management

Manage captured speech, voiceprint models, verification information, and call records in one place.

System architecture

Deployment
that fits your business.

Review SIP integration, audio capture, and customer systems, then choose an add-on or standalone deployment according to network conditions and call volume.

Existing systems

Review business systems and integration needs

Network isolation

Define network conditions and isolation requirements

Business scale

Evaluate capacity and expansion requirements

Advantages

Keep your phone services.
Add voiceprint capabilities.

01

Two deployment options

Add a voiceprint module to an existing call center or deploy a standalone telephone voiceprint system.

02

Two verification approaches

Use text-independent or dynamic-passphrase verification according to the scenario.

03

Use existing recordings

Create models from call recordings or use historical call audio for offline modeling.

04

System integration support

Custom development connects to other business or biometric verification systems.

Workflow

Build models first.
Compare voices in later calls.

  1. Prepare speech and create models

    An unregistered person's first call produces no recognition result. Use that recording to register a voiceprint afterward, or model from historical audio offline.

  2. Provide results during calls

    During subsequent calls, capture and analyze speech against registered models to provide identity recognition results.
