7 Reasons to implement Cloud based Voice Biometric today

What is Voice Biometric Authentication?

From privacy and security, to ease of use and savings. Discover how your business can benefit from cloud based voice biometrics.

Voice Biometrics characterises a person's voice for use in Speaker Verification - an application of AI-based voice technology that uses a voice imprint to authenticate or confirm an individual’s identity. Various vocal features and attributes such as pronunciation, pitch, tone, dialect, and style of speech all contribute to our vocal identity and allow verification / authentication for users. This process is extremely fast (think tens of milliseconds), needing only a couple of seconds of speech to store the voiceprint. That is why it is already used in many systems and services that have become an integral part of our daily routines, such as Google Voice, Amazon Alexa, and other virtual assistants.

Here are 7 reasons why your organisation should implement cloud-based Voice Biometrics technology today.

1. Fighting Fraud

Voice biometric systems operate on hundreds or even thousands of features of the human voice, making verification highly accurate, and a powerful tool in fighting fraud. Adding voice biometric technology not only reduces the risk of fraud by identifying the customer unambiguously, but also protects victims of fraud and impersonations, the customers themselves. Call centers today, with the help of voice biometrics, are already building real-time databases of “blacklisted voiceprints” as a security measure.

2. Security

The traditional verification methods like password or PIN can be easily tracked or hacked, while the voice of an individual can be as distinctive and unique as the fingerprints captured by many computer systems. That’s why Voice Biometrics are being implemented in large scale applications such as remote banking, government e-services and healthcare. Groundbreaking advances in Artificial Intelligence (AI) and the science of Big Data, give Voice Biometrics the ability to identify a speaker, rapidly and reliably. Voice Biometric APIs, such as VoiSentry’s, enable developers to add enhanced security and convenience of biometric voice authentication to their customer contact applications.

3. Privacy & Engagement

Voice Biometrics keeps the privacy of users intact, and the end-users engaged.

With other authentication methods, simple PINs or passwords are usually supplemented with personal information such as mother’s maiden name, date of birth, or a pet’s name. But many end-users are reluctant to share such information with more than a few services – they quite rightly believe that doing so makes their accounts far more vulnerable to attack, because once one such service has been breached, an attacker will have easy access to all the other services.

What’s more, some of this information can be inconvenient to use – it can be forgotten, or sometimes expressed or spelled out in different ways (different capitalisation, optional punctuation marks, etc.) – causing confusion and delays in accessing services or systems.

Whatever the reason, simple knowledge-based authentication makes for an experience that is tedious and uncomfortable for users. The key is to find methods of authentication and verification that are effective, accurate, and easy for customer engagement. Voice Biometrics is often the only feasible method to achieve all these aims simultaneously.

4. Operational Cost Savings

Several use cases for voice biometric authentication show immense operational cost savings including Contact and Call Centers that are traditionally agent-assisted. With voice biometrics, the customer is identified, authenticated and routed to the appropriate call flow via IVR for processing their request, without any human interaction. Voice Biometrics reduces the average authentication time by up to 80%, which also frees up the agents, meaning they can be more engaged in focusing on other complex issues without compromising the customer experience.

5. Ease of Use

Voice Biometrics is a win-win for users. Rather than customers memorizing their passwords or keeping them saved in their notebooks and phones, a voice biometric system can verify their identity with only a short sample of their voice – whether taken from a natural conversation or in a more controlled fashion.

In many situations, a Voice Biometric solution is the only technology that can provide reliable authentication with such ease – there is no need for a keyboard, a web-cam, or any special hardware such as a fingerprint reader, and there is virtually no overhead in terms of overall transaction time.

What’s more, the most powerful Voice Biometric systems are language-independent, recognizing unique voice characteristics regardless of language or accent. This is especially important in regions where multiple languages or dialects are spoken.

Voice Biometrics can provide a smooth user experience that still accurately verifies the identity of customers.

6. Foster accessibility

Voice biometrics solutions are suitable for almost everyone, including many of those with speech-related disabilities. “A good language-independent Voice Biometric system relies on the voice characteristics rather than the actual words spoken.” Wheeler (a digital analyst at Aculab, who has cerebral palsy and limited speech) explained. “This means it can still be used by people with impaired speech.”

Voice Biometrics provider, Aculab Cloud, has recently published a blog post illustrating the accessibility features of its VoiSentry Speaker Verification & Identification (SVI) system.

7. Get started Quickly

Voice Biometrics can be implemented easily on your platform of choice – hardware server, data center, cloud, or even a SaaS pay-as-you-go model. Best of all, it is highly scalable and can be applied in a variety of different applications such as contact centers, healthcare management, public services and financial systems.

These flexible integration options make it simple to implement cloud-based Voice Biometric solutions. Aculab VoiSentry with SaaS, cloud-based and / or subscription-based models, enables developers to add the enhanced security and user convenience of biometric voice authentication to their customer contact applications within hours.
