An in-car navigation system has been developed that eliminates the hurdle of high retail costs now restricting the widespread market penetration of navigation systems. Most commercial navigation systems utilize expensive location devices such as Global Positioning Satellite (G.P.S.) systems to ensure that the vehicle “knows” where it is at all times. Additionally, these systems typically use some mechanical means to input the destination. The Amerigon AudioNav does not use expensive location devices and sensor systems. It is voice operated, using state-of-the-art speech recognition technology and recorded speech to communicate with the driver. This paper describes the AudioNav system and details the system's benefits by discussing its capabilities and performance.
