This text describes the integration of voice biometric authentication using Twilio's API with VoiceIt, a voice print portal service. The technology allows users to log in using their voice, making it more secure than traditional passwords or PINs. The system uses digital sampling techniques to recognize a speaker's voice and can be used for various applications such as two-factor authentication. The code provided demonstrates how to set up this integration using Node.js, Express, and Twilio APIs. It covers the enrollment process, where users repeat phrases multiple times to create a unique voice print, and the authentication process, where users are asked to speak their enrolled phrase to verify their identity. The system provides feedback to the caller based on the outcome of the authentication attempt.
