Abstract: The purpose of this study was to identify the potential problems of an in-vehicle speech interaction system named Talking Car by using the techniques of risk assessment. In this study, there were 16 participants asked to complete the assigned tasks by controlling the Talking Car system while driving. By conducting the driving simulation experiment, the failure modes, the incorrect operations, the failure causes and the effects were observed and collected. Then, a modified Failure Mode and Effects Analysis (FMEA) method which took human operation into account was used to determine and analyze these failure modes and incorrect operations. After completing the analysis, the Risk Priority Number (RPN) is computed to detect which failure made a significant effect on driving safety. As a result, RPN and subjective questionnaire indicated that “System Sentences with Elicitation”, “Control Button on Steering Wheel” and “Partial System Interface” should be improved urgently to ensure driving safety.
