Voice Verify DEMO

For demonstration purposes we created a Voice Verify DEMO. By using this demo you can get a feel for Voice Verify in a couple of minutes even without any programming or technical knowledge. This DEMO helps you understand the process of enrollment and verification and let’s you try our technologies on your own voice.

The only requirements for using our DEMO are:

  • a mobile phone to receive incoming call
  • a web browser
  • username and password created by Phonexia for login

 

Voice Verify SANDBOX

Phonexia Voice Verify SANDBOX is a cloud appliance accessible via RESTful API that enables testing of our technologies on one’s own recordings. The SANDBOX allows clients to get a feel for the complete Voice Verify solution and simulates a real communication scenario between Voice Verify and another software.

Requirements for using our SANDBOX are:

  • RESTful API knowledge
  • custom SANDBOX link generated by Phonexia

The Sandbox is focused only on voice verification, in which case you expect a certain speaker on the line and ask the question “Is the speaker calling right now really the person you expect him to be?”.

 

Technology behind Voice Verify

Voice Biometry

To verify a speaker, Phonexia Voice Verify uses the power of voice biometry to recognize speakers automatically by their voice with extremely high accuracy.

Voice biometry is based on the fact that the speech organs and speech habits of every person are unique. As a result, the characteristics of the speech signal captured in a recording are also unique, thus the technology can be language-, accent-, text-, and channel-independent.

Phonexia’s voice biometry technology is called Speaker Identification. Speaker Identification is based entirely on deep neural networks called Phonexia Deep Embeddings™.

Speaker Identification

Speaker Identification extracts the features from a voice to a voiceprint. A voiceprint is a small numerical representation of the voice.

The whole voice verification process consists of two parts:

  1. speaker enrollment – a speaker that is not already in the database has to be enrolled – this is done by creating a voiceprint from his voice sample and saving it to the database
  2. speaker verification – two voice samples are compared to decide if their voices belong to the same speaker – this is done by voiceprint comparison

Accuracy and calibration

Voice biometry is (as well as finger or face biometry) never absolutely perfect.

Two types of mistakes can occur:

  1. false acceptance of a person
  2. false rejection of a person

Based on these possible mistakes, accuracy can be measured. Phonexia’s Speaker Identification achieved a stunning 97% accuracy on call center datasets.

The accuracy can be boosted further with a calibration. Calibration adapts the Speaker Identification technology on a specific customer environment.

Voice Verify

In the picture below you can see a basic technical flowchart describing interactions with Voice Verify.

1.

Voice Verify is designed to process SIP (Session Initiation Protocol) based calls, HTTP streams or WebSocket streams as voice input. This means that it is a matter of configuring the Call Center’s PBX (Private Branch eXchange) or other audio source to fork each call and send a copy of the customer’s voice to Voice Verify.

2.

After Voice Verify receives the voice, it is able to process it with Speaker Identification voice biometric technology. It can either enroll this voice into a database or verify againts already existing voiceprint from the database. This way it is able to verify customer’s identity.

3.

Voice Verify provides result of verification of the consumer to the client’s Call Center software via RESTful API. The verification information needs to be incorporated into the client’s processes and software.
