System and electronic equipment for voice guidance with speed change thereof based on trend

摘要

A voice guidance system is provided in which the voice guidance is enabled to easily follow a trend of change intervals, a rapid change of change intervals, etc. in a menu operation. The voice guidance system is configured with an input analyzing unit which inputs and analyzes an operation instruction signal of a menu item, a voice guidance control unit which controls voice guidance of the menu item according to the analysis result by the input analyzing unit, and a textual guidance control unit which performs display control of the menu item according to the analysis result by the input analyzing unit.
