# Voice

**Voice capture Widget v.1.0.2**

### **Introduction** <a href="#introduccion" id="introduccion"></a>

Voice authentication is a process that allows verifying the identity of users through voice biometric technology.

To carry out user authentication, a single prior biometric registration step is required to verify identity. Once registered, the authentication process involves capturing the voice, which, compared with the previously registered one, will allow the user to access the product and/or service.

### **Requirements and installation** <a href="#requisitos-e-instalacion" id="requisitos-e-instalacion"></a>

To be able to use Facephi Authentication, you must have a compatible browser on your device, whether on a desktop computer or a mobile device. The compatible operating systems and browsers are:

* Windows, macOS, Android, iOS.
* Mozilla Firefox, Google Chrome, Opera, Safari.
