If you read our voice biometrics tutorial, you are now fully aware of the importance of capturing the cleanest possible audio to get a valid result from a voice biometrics engine.
For a Passive voice biometric system, the person speaking does not know that the voice biometric analysis is happening. Therefore, getting the best audio means attending to the system recording components and creating an experience for the speaker that leads to capturing speech without becoming artificial and obvious that speech is your objective.
On the other hand, for the Active voice biometric use case, in which the person speaking is knowingly participating in the authentication process, it stands to reason that training the user to interact with the system properly will have a large impact on your results. Experience has absolutely shown this to be the case. You can and should be explicit with your instructions and guidance in order to encourage behavior that achieves the best results for both the person speaking and your business. By doing so, you will achieve higher user satisfaction and also avoid the majority of support tickets related to voice biometrics.
In order to help you train your users, we publish a Best Practices Training Guide in our customer help center, available within our dashboard to production customers. Several of the principles to keep in mind as you educate your users are the following:
By keeping these ideas in mind, you will increase the effectiveness and efficiency of your voice biometrics system, achieving both a higher user satisfaction and acceptance rate as well as minimizing your support costs.
