Homer Simpson is the latest "celebrity" voice to join the TomTom GPS voice lineup, the GPS maker announced on Tuesday. Users can visit the TomTom site and download the voice for $12.95, or €9.95 in Europe. As you might expect, the voice of Homer (actually voiced by Dan Castellaneta) provides some occasional commentary, such as: "Take the third right." "We might find an ice cream truck! Mmm…ice cream." TomTom already offers seventy official voices for its navigation devices, although user-based uploads can add more. "Celebrity voice downloads are one of the many features TomTom offers to our customers to personalize their driving experience," said Jocelyn Vigreux, president of TomTom, in a statement. "With Homer Simpson's voice helping them to navigate their trip, TomTom customers will not only travel safely and with less stress, but will also be highly entertained along the way."
