The benefits of voice identification

Voice identification is a safe, secure and convenient form of biometric authentication that extracts personal voice patterns to verify an individual’s identity.

This biometric modality can be used over the phone, with or without using specific words or phrases – and there’s potential to combine them with spoken passwords for added security.

Voice biometrics is commonly used in call centres for faster authentication and are also being used increasingly in daily life with mobile phones and other smart speaker devices.

Voice Identification

Voice recognition works by analysing over 100 physical and behavioural factors to produce a unique voiceprint for each individual. These factors include pronunciation, emphasis, speech speed and accents, and also physical characteristics such as vocal tract, mouth and nasal passages.

Voice identification occurs in two forms: It can be passive, where a user’s speech is matched to a previously recorded voiceprint. Or it can be active, where callers are asked to recite a predetermined passphrase and their voice matched to the voiceprint saved in a database.

Vocal capture:

A voiceprint is created by reducing each spoken word to segments composed of several dominant frequencies, that are then segmented by tones captured in a digital format. Those tones collectively identify the speaker’s unique voice print which becomes their unique vocal pattern.

Business applications

Voice identification has common business uses within contact centres, visitor management and in consumer applications for access.

Call Centre Engagement

Access Control

Visitor Management

Industry solutions

Voice recognition systems are typically utilised in contact centres where there is no other method for physical authentication. However, it can be used across a wide range of industries such as;


Retail and Logistics

Banking and Finance

Benefits summary

Voice recognition is a method of security that can be accessed by almost everyone. It provides those with visual impairments the same level of security as those without. Similarly, technologies that require physical interaction may prove difficult for users with certain disabilities, but due to voice recognition being the analysis of vocal patterns, this can remove a physical barrier that other methods of technology may carry.

Contactless & non-invasive
The contactless nature of this modality is unobtrusive and hygienic compared to touch-based systems, and thus brings a higher level of comfort and acceptance to users of the technology.

With no specific biometric hardware required, it is widely-recognised as one of the most cost-effective solutions when you need certainty of identity due to its ability to be used with simple hardware such as a microphone.
