Aware Nexa Voice - Frequently Asked Questions
Frequently Asked Questions about Aware’s Nexa|Voice
What is Nexa|Voice and how does it work?
Nexa|Voice is a mobile voice authentication SDK that uses biometric speaker recognition algorithms to verify an individual’s identity. It captures and analyzes a person’s unique vocal characteristics, such as duration, intensity, dynamics, and pitch, to create a “voiceprint” that is used for authentication. This voiceprint is then matched against a reference template to verify the user’s identity.What are the different types of voice authentication offered by Nexa|Voice?
Nexa|Voice supports two main types of voice authentication: text-dependent and text-independent. Text-dependent authentication requires the user to speak a specific phrase, which can be static or dynamic (e.g., a randomized passphrase). Text-independent authentication allows the user to say anything, and the system authenticates their voice in the background.Where can the biometric templates be stored?
The biometric templates generated by Nexa|Voice can be stored either on the mobile device itself or on a server. This flexibility allows for different deployment scenarios depending on the application’s requirements.What are the advantages of using Nexa|Voice for authentication?
Nexa|Voice offers several advantages, including wide accessibility on mobile phones, cost-effectiveness for integration into various devices, convenience and familiarity for users, and a contactless, hygienic authentication method. It is also useful for phone-based use cases such as customer service.What are the potential disadvantages of using Nexa|Voice?
Some disadvantages include lower accuracy compared to other biometric modalities like facial recognition, the need for liveness detection to prevent spoofing with recordings, and the impact of background noise on sample quality and matching performance. Additionally, it may not be ideal for noisy or public environments.How secure is Nexa|Voice?
Nexa|Voice is highly secure because it uses a proprietary representation of the voice template, not the actual voice recording. Even if the voice template is stolen, it cannot be used without the authentication provider’s proprietary decoding process. This makes voice biometrics extremely secure against unauthorized access.Can Nexa|Voice be integrated with other biometric modalities?
Yes, Nexa|Voice can be integrated with other biometric modalities as part of the Knomi mobile biometric authentication framework. Knomi offers multiple biometric options, including facial recognition, keystroke dynamics, and voice authentication, allowing for strong, multi-factor, password-free authentication.What are some common use cases for Nexa|Voice?
Nexa|Voice is particularly useful for hands-free mobile authentication, such as in automobiles or other settings where other biometric methods are inconvenient. It is also used in speech-recognition devices like Google Home or Amazon’s Alexa, and in customer-support calls to verify identities securely.How does the enrollment process for Nexa|Voice work?
The enrollment process involves capturing a voice sample from the user using a microphone. This sample is then sent to a biometric engine, which creates a unique voice template or “voiceprint” based on the user’s vocal characteristics. This template is used for future authentication attempts.Is Nexa|Voice language-independent?
Yes, Nexa|Voice is language-independent, meaning it can authenticate users regardless of the language they speak. This makes it versatile for use in diverse linguistic environments.What kind of technical support does Aware offer for Nexa|Voice?
Aware provides collaborative technical support for Nexa|Voice, ensuring that users have the necessary assistance to integrate and use the SDK effectively.
