A voice response translator helps facilitate communication between police officers and members of the public who do not speak English, explains the National Institute of Justice. As of 2015, the military also uses voice response translators to communicate with citizens of foreign countries.
The Navy and Coast Guard are two examples of military branches that use voice response translators, according to the National Institute of Justice. The Coast Guard often deals with boarding speakers of foreign languages at sea, and voice response translators help ease communication. In the Iraq war, the Navy used translators to steer foreign ships away from oil rigs in the Persian Gulf. In law enforcement, voice response translators generally help with patrolling tasks such as checking driver's licenses and other pullovers.
