I’m Clive Summerfield, Managing Director for LumenVox EMEA [Europe, Middle East, Africa] Australia and New Zealand, and I’m here to talk about Active Voice Biometrics. Many of you may have actually heard about Voice Biometrics, and I’m here to talk about the particular benefits of Active Voice Biometrics as opposed to Passive Voice Biometrics.

Q: What is Voice Biometrics?

Voice biometrics is a technology that allows a system to authenticate the identity of a person from an analysis of their voice. Like your fingerprint, your voice is unique. And so, like your fingerprint voice can be used as a very powerful technology for authenticating the identity of the speaker: you actually are who you say you are. And that’s a literal statement; the voice and the sound wave that emanates from your lips and your nostrils contains within it an acoustic signature that is unique to that individual speaker. And that in a nutshell is what Voice Biometrics is all about.

Q: What’s the difference between Active and Passive Voice Biometrics?

Voice biometrics comes in two flavors, essentially. There’s Active and Passive Voice Biometrics. Active is where a system asks you a specific question, and you have to answer that question with the correct voice. The obvious one here is a phrase like “My voice is my password,” but it can be anything—it can be your name; it can be your date of birth; it can be your address, your zip code or here in the UK your post code. It could be an account number or your telephone number. So this is where Active Voice Biometrics is Actively verifying your identity from a phrase that you’re actually saying. In Active Voice Biometrics you have to say the correct phrase with the correct voice. Now Passive on the other hand is a technology that sits in the background and listens to a conversation. Passive Voice Biometrics is, as the name implies, passively listening to a conversation and just understanding the voice characteristics of the speakers to recognize who the speakers are.

Q: Where is Active Voice Biometrics most appropriate?

The ideal application for Active Voice Biometrics is in telephone self-service and particularly for authenticating identity of speakers using IVR systems, particularly self-service applications—such as banking applications, government applications, applications for retail and telecommunications services. So in those applications the IVR prompts you for a piece of information. “Please say your telephone number.” And you have to say the correct telephone number with the correct voice in order to positively authenticate your identity, giving you a very strong level of surety that the speaker is the account holder and not an imposter trying to break into your accounts.

I feel like the big application for Active Voice Biometrics has been in telephone-based password reset. And there are numerous examples of Active Voice Biometrics being used for telephone password reset applications, and those are principally in help desks and internal-facing employee helpdesk applications and services. But Active Voice Biometrics is far more than just a password reset application; it is also a password replacement technology where voice can be used instead of passwords for many applications. These include IVR telephone self- service chat bots and increasingly online services and IOT devices.

Q: What about the future of Active?

Well, there is good news in that voice interactions are growing in the world, I mean, despite the demise of telephone call centers, the growth in voice communications is growing exponentially at the moment. According to Gartner, 30% of all searches are now voice-driven which tells you where voice communications is going in the future. So the digital channel is where all the action is actually going to be in the near term.

And whilst Active still has a very important role to play in telephone services, the future of Active is actually in the digital channel. Now digital channels are almost by definition driven by phrases and single phrases, which is where Active has very strong application over and above Passive. So Active is the only technology in the digital channel that is applicable for things like second-factor authentication. I like to think that Voice Biometrics and Active Voice Biometrics is actually the world’s best second-factor authentication which can be used to augment things like PINs and passwords that are traditionally stored up now in browsers. Active Voice Biometrics can be very effectively applied in digital channels and particularly in second factor authentication for browsers channels.

One of the big applications for Active Voice Biometrics is capturing voice through the browser as somebody is accessing a secure website such as Internet banking and other services of that nature, to positively authenticate that the person who is actually the account holder. This provides a much stronger security credential than PINs or passwords on their own. And Active is unique in so far that it’s the only technology that can harmonize the authentication between the emerging digital channels and the legacy telephone channels. You can use the same phrase in a digital channel as you can in a telephone channel. There’s no other biometric technology that provides this type of flexibility which means that organizations can harmonize their authentication strategies across all their customer service channels thereby providing a much more effective customer service experience.

3 Key Strategies for Credit Unions {in the Time of COVID}

3 Key Strategies for Credit Unions {in the Time of COVID}

There are three key issues on credit unions’ minds right now: Fraud, operations, and member experience. Fraud is a rising issue due to uncertain economic times. Operational efficiencies are a high priority because the contact center is now being inundated with calls—time, more than ever, is money. Member experience is always at the top of the priority list because it inspires every roadmap.

Is there a solution that can address all three?

There is. Passive Voice Biometric Authentication effortlessly authenticates members over the phone during the natural course of conversation with an agent. Members register their voiceprint, and on subsequent calls, their voice is matched to this unique identifier, giving the agent a green light when the identity claim is genuine and a red light when a fraudster is attempting an account takeover. This solution addresses these areas with these three key strategies for credit unions to tackle the following:

Fraud Detection

Passive voice biometrics, including fraudster detection, is a layer of security that seamlessly works with humans to prevent mistakes that often go unnoticed today. When a call comes in, the caller’s voice is compared to the voiceprints of known fraudsters. The agent is alerted and coached from there to take evasive action.

Operational Efficiencies

Reduce Agent Handle Times. Agents dread the first few minutes of every call. With LumenVox Passive Voice Biometric Authentication they can start solving the caller’s problem with confidence, verifying identity within seconds, not minutes. LumenVox Passive Voice Biometric Authentication results in reducing AHT by 30 – 60 seconds per call. This drives cost out of the contact center and improves your bottom line.

Member Experience

According to a study by Salesforce, 84% of customers say the experience a company provides is as important as its products or services. Voice biometrics enable your credit union to give your members a positive authentication experience, from the very beginning of the call. With LumenVox Passive Voice Biometric Authentication the member can be authenticated while speaking comfortably and naturally to an agent, reducing the need for a long line of interrogative questioning. Contact centers with passive voice biometrics start by asking their customers “How are you today?” instead of “Who are you, and are you who you say you are?”

On Voice Biometric Privacy and Informed Consent

On Voice Biometric Privacy and Informed Consent

It was recently announced that a biometric data privacy suit implicated the voice biometrics company, Pindrop. According to the plaintiffs, informed consent requirements were not followed when collecting, storing, and utilizing voiceprints to authenticate customers for Amazon Web Services, which the plaintiffs claim violates the Illinois Biometric Information Privacy Act (BIPA).

This scenario is exactly what LumenVox works hard to avoid. Since LumenVox is headquartered in California (where the biggest giants of customer data work, such as Facebook and Google) and operates internationally, we understand that customers demand privacy. There are now stringent laws in place, such as the California Consumer Privacy Act and GDPR, to make sure that just as a company’s technology evolves, so must the strategy to correctly collect, handle and store sensitive consumer data.

When it comes to any biometrics modality, informed consent is key. LumenVox advises our customers and partners to include a very clear information flow to gain informed consent for both active and passive voice biometrics. As a voice biometrics provider, education, training, and guidance are three things we pride ourselves on as we work closely with our clients on voice biometric deployments.

Biometric solutions have been around for decades now, but understandably consumers and businesses still have their reservations. What’s particularly comforting about voice biometrics is the way voiceprints are stored – with Personal Identifiable Information (PII) decoupled from the voiceprint. This means a consumer’s voiceprint is matched to a string of 0-s and 1-s, numbers that would mean nothing to a malicious actor.

This news inevitably raises questions: Is voice biometrics safe? Yes. Can it be used to protect customer data? Yes. Is informed consent key when utilizing it? Absolutely. At LumenVox, we strive to put customers first, every step of the way.

The Reality of Synthetic Voice Attacks

The Reality of Synthetic Voice Attacks

Voice biometrics provides a robust layer of security for contact centers, using the physical and behavioral characteristics of a voice to verify claimed identities. But just as businesses are adopting new voice biometric technology, fraudsters continue to advance and adapt techniques to take over customer accounts.

There has been concern expressed that voice biometrics is vulnerable to a certain level of sophisticated fraud. This concern rises with the evolving technology surrounding synthetic voices. A synthetic voice is a collaboration between a human being and a machine to produce an artificial version of human speech.

The truth remains: Fraudsters can indeed try to elude biometrics authentication using synthetic voices. And yet this truth doesn’t scare us, and here’s why:

  1. Synthetic speech leaves evidence, a trail. It generates specific artifacts which makes this type of speech detectable.
  2. Even in the best of cases, the synthetic voice doesn’t sound entirely human. With passive authentication, there is always an agent who acts as a spoofing detector. It’s very easy for humans to correctly distinguish synthetic speech from real human speech. As humans, we know when something sounds off.
  3. The reality is fraudsters follow the path of least resistance; they want to work the fewest number of hours for the biggest amount of payoff. The creation of a synthetic voice requires a very high level of effort. The best deep fake or synthetic voice technology currently needs a substantial amount of audio data to train the voice. Getting this in normal circumstances is difficult, and yet not impossible. While there are tools that exist which generate synthetic speech, they require a certain level of skill/ expertise to utilize. These combined factors act as a natural deterrent.

Having made those points there is another truth which remains: All the detection, human intervention, and natural deterrents in the world do not necessarily equate to peace of mind. At LumenVox, we encourage the use of voice biometrics alongside traditional authentication methods, including PINs, passwords, security questions, so that customers are protected with multiple layers of security.

How to Increase IVR Containment

How to Increase IVR Containment

The number of customers calling organizations to request a promise to pay is increasing significantly with these uncertain financial times. The result is a tsunami of phone calls that contact centers can’t handle. This leads to further customer frustration and stress during an already difficult period. It also drives up costs in the contact center with no associated increase in revenue, making it a losing proposition for all involved.

Imagine this scenario: A customer recently lost his job and can’t afford his utility bill. He’s already called the contact center once to defer the payment due date. Admitting to a contact center agent that he can’t afford to pay on time is already frustrating and embarrassing. The problem now is that he knows he can’t pay the full amount, so he calls again to request a payment arrangement.

Every time he calls, he’s asked the same series of questions: account number, street address, last four digits of his social. When he finally reaches the IVR menu, a set of submenus is presented. Then there’s a transfer to the contact center itself, with long wait times. Finally, the customer reaches an agent who can set up a payment plan. It’s laborious, time-consuming and ultimately leaves the customer more stressed than when he started.

The solution to this painful process is increased self-service in the IVR and secure, effortless authentication.

With a few tweaks to the existing IVR, this customer can hear a personalized greeting based on his ANI (caller ID). The IVR can also immediately identify a past due bill and ask him if he is calling to request a promise to pay (or set up a payment plan). If the answer is ‘yes’, the caller is authenticated with a simple passphrase, such as “My voice is my password.” The promise to pay or a payment plan is then completed and the call ends. The customer has a streamlined experience without requiring interaction with an agent. Additionally, IVR containment is achieved; a contact center agent handles one less call – saving money and improving wait times.

LumenVox enables organizations to exceed expectations, even during these stressful times, with state-of-the-art speech recognition and voice biometrics. The use of these technologies can provide material cost savings with a demonstrated return on investment. They can also help customers accomplish their goals quickly using the IVR, one of the least expensive channels available.
