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.

First Claim:
Show all 16 claims
What is claimed is:     1. A dialog car system comprising:
  • a speech recognition circuit, operative to receive words an sounds uttered by a drive of a vehicle, and to produce decoded voice signals corresponding to said words and sounds;
  • a natural language processor coupled to receive said decoded voice signals output by speech recognition circuit, and being operative to process and produce responses based on said decoded voice signals;
  • a speech generator, responsive to an output derived from said natural language processor, for generating speech for the driver to hear so as to carry on a dialog with the driver;
  • an analyzer, coupled to said natural language processor and said speech recognition circuit, for analyzing the words and sounds uttered by the drive and to determine whether the drive is alert or about to fall asleep; and
  • a conversational planner, coupled to an output of said driver analyzer for planning the type and content of speech to generate by said speech generator, wherein said conversational planner comprises means for receiving indications of conditions of the driver, means for continuing the dialog when said conditions of the driver are within an acceptable level, and means for changing the dialog when at least one of said conditions of the driver is outside an acceptable level.
