Abstract: An automatic dialog system capable of keeping a drive awake while driving during a long trip or one that extends into the late evening. The system carries on a conversation with the driver on various topics utilizing a natural dialog car system. The system includes an automatic speech recognition module, a speech generation module which includes speech synthesis or recorded speech, and possibly dynamically combined speech synthesizer and recorded speech, and a natural language processing module. The natural dialog car system analyzes a driver's answer and the contents of the answer together with his voice patterns to determine if he is alert while driving. The system warns the driver or changes the topic of conversation if the system determines that the driver is about to fall asleep. The system may also detect whether a driver is effected by alcohol or drugs.
