In a car navigation system, a voice guidance system is equipped to ensure the safety of driving. On the other hand, a driver requires a certain period of time to understanding instructions from the voice guidance and may misjudge them. To solve these problems, we propose a new expression (SVN) process of the voice guidance based on drivers’ soliloquy. When drivers confirm a point to turn or a distance to the point based on the voice guidance, they quite often make correspondence the expressions of the guidance to their own expressions. Such the expression in the brain of a driver is expected to be similar to the soliloquy type expression of the driver. We assume that the soliloquy expression of the guidance will be understandable easier than the conventional expression. We conducted the experiment on the driving simulator to verify our hypothesis. The results suggest that SVN decreases the time for understanding the instruction and the frequency of misjudgment.
