Adding Voice Bio Security

Adding Voice Biometrics Security is as Easy as A-P-I

Unsurprisingly, security is critical to successful business operations across numerous industries. As an automated programmable-AI software company, Plum Voice provides users with tools, such as Plum Fuse, that enable them to create different forms of voice authentication methods. Naturally, as a company that creates AI-voice automation solutions, it makes sense to highlight the benefits of voice biometrics with 2FA/MFA security options.

There are two elements to voice biometrics – voice registration and authentication – that will be reviewed below.

Authentication With Voice Biometrics

Voice Registration

Voice registration entails talking to the voice biometric engine long enough so that it can create a voice print for an individual. A voice print is a digital model of an individual’s unique vocal characteristics. Like other human biometrics such as facial recognition and fingerprinting, it uses AI-machine learning to help software providers or businesses create the identities of their customers. 

One method for creating a voice print is to use a random number case approach. In this use case, the voice biometric API prompts the user to recite a string of random numbers. An IVR system captures this audio and sends it to the voice biometric API. If there is a successful match, the IVR system then moves to another random string of numbers. This process is repeated until the voice biometrics API determines that it has enough samples to create a voice print. Typically, this is in the range of 4–6 audio samples.

Voice Biometrics Authentication

After the voice biometric engine has created the voice print – authentication becomes even simpler. During subsequent calls to the same company, the caller’s voice is verified against the voice print already in the voice biometric system. Because of this voice registration only needs to be done once which makes the voice biometrics authentication process a fast, and efficient 2FA/MFA security measure solution once it’s set up.

Robust Voice Biometrics API

At Plum, we’ve created our own REST API (or shim layer) specifically for voice biometrics. A REST API is an application programming interface that conforms to the constraints of the REST architectural style, and allows for interaction with the RESTful web services – REST means representational state transfer.

Our developers have done the hard work of evaluating numerous voice biometric APIs. Only the engines that meet our high standards and internal testing made the final cut into the API. Our developers continue to assess different voice bio vendors in order to offer the best combination of reliability and ease of use through a single API. You can click here to learn more about APIs and how they are used.

Normalizing multiple voice biometric engines in an easy to use API allows us to offer increased flexibility without a corresponding increase in development complexity. The voice biometric API brings the most common commands to the forefront, and pushes everything else to the background to make integration smoother.

At the heart of our voice biometrics API are the commands to manage user creation and validation, to initiate voice print enrollment for both new and existing users, and to authenticate users. The end result streamlines the creation and authentication of voice prints through an interactive voice response system application.

Integrate Voice Biometrics into Applications

Thanks to our voice biometric REST API, developers can easily boost the security of their DEV voice automation applications. A custom-made JavaScript helper library maintains the API endpoints and provides functions to parse XML DOM responses. It can also be used to build remote grammars for ASR (automated speech recognition) matching, making voice biometrics much more usable. Developers can trigger this helper library by adding a single line of code to their VoiceXML script.

Without the assistance of the REST API and the JavaScript helper library, developers would have to connect everything directly between the voice biometrics engine and their voice application in a traditional, high level programming language. If your company wanted to change voice bio vendors or test different voice engines to see which one works best with your application, then developers would have to re-write all of the integration code to fit the new engine. A custom API makes testing different voice biometric systems or platforms a breeze. Plum Voice’s Voice Biometrics API makes voice biometrics a plug-and-chug coding option because it is designed to handle multiple engines.

Benefits of Voice Biometric APIs

The benefits of voice biometrics and multi-factor security authentication is all well and good, but if these additional features aren’t cost effective or are difficult to implement the ROI drops. Plum makes voice biometric authentication easy to implement into voice communications, reducing the number of hours that developers need to spend on it. This makes its security benefits even more attractive because it provides a strong layer of security as a standalone or as part of a multi-factor authentication process.

Voice Biometric Solutions for Developers

Voice biometric APIs can be highly beneficial for software developers working on projects for clients. Below are a few examples where developers can implement voice biometrics to enhance the functionality and security of their applications:

Test Results

Mobile banking and financial apps: Software developers can integrate voice biometrics into mobile banking or financial apps to provide an additional layer of security for users. Users can authenticate their identities with their voice when logging in, making transactions, or performing other sensitive operations. This adds convenience to the user experience and reduces the risk of unauthorized access or fraudulent transactions.

Healthcare applications: In healthcare, developers can use voice biometrics to create secure applications that protect sensitive patient information. By implementing voice authentication, healthcare professionals can access patient records, treatment plans, or prescription information using their unique voiceprints. This not only helps maintain the confidentiality of patient data but also complies with privacy regulations like HIPAA.

Smart home and IoT devices: Software developers working on smart home or IoT solutions can utilize voice biometrics to provide personalized experiences and secure access to users. By integrating voice recognition capabilities, developers can create devices that recognize and respond to specific users, allowing personalized settings and access to restricted functionalities. For instance, a smart home system could be programmed to recognize each family member’s voice and provide access to individual profiles or preferences, enhancing both security and convenience.

Voice Biometrics Solutions for Businesses

Policy Information

Customer authentication in call centers: Voice biometrics can be used to authenticate customer identities during phone calls to call centers. By analyzing unique voice characteristics, the technology can quickly and accurately verify a customer’s identity. This reduces the need for time-consuming security questions, streamlining the process and improving the customer experience while maintaining a high level of security.
