To improve police officer safety, the University of New Hampshire (UNH) and the New Hampshire State Police, with funding from the US Department of Justice, have been collaborating on Project 54, a state-sponsored program that outfits police cars with a speaker-independent voice interface to control many in-car systems. With Project 54, an officer needs only to hit the push-to-talk button on the steering wheel, say the command "Coast Guard," and the system automatically locates the frequency. Developing the Project 54 system was no easy task at first. Perhaps one of the biggest hurdles for UNH teams was the proprietary nature of many of the in-car systems in use. Currently, the Project 54 speech interface maintains an 85% task completion rate.
