As you can hear with the audio file sample, the reassuring voice directions will help TELL the person how to travel safely to high ground during a volcanic lahar.

How will this happen?  GPS coordinates, along with the best evacuation routes, will be preprogrammed into the computer files, and corresponding audio files will also be preprogrammed.  So, the microprocessor will match the GPS location and the mapped direction with the proper audio file.
