A NAVIGATION DEVICE FOR A LAND VEHICLE WITH MEANS FOR GENERATING A MULTI-ELEMENT ANTICIPATORY SPEECH MESSAGE, AND A VEHICLE COMPRISING SUCH DEVICE

摘要

A navigation device for a land vehicle with means for generating a multi-element anticipatory speech message, and a vehicle comprising such device. A navigation device for a land vehicle senses vehicle displacement and stores map data. Matching of the displacement to the map data produces actual position and motion of the vehicle. Under control of user input, an intended route from an actual position to a destination is calculated. Under control of actual motion and with respect to selected elements of the intended route an anticipatory speech message is generated from a speech message directory. The message comprises a sequence of a message location prefix, a message action advice, and a message outcome suffix. The elements of the sequence may be represented in the directory by synthetic or recorded natural speech.
