Voice control system

摘要

A speech recognition (SR) dictionary switching unit selects a SR dictionary including commands that are for controlling target devices and selectable in current operating states detected by a device-state detecting unit. When a SR engine recognizes an uttered command of a user, it collates the speech with the commands included in the selected SR dictionary. Commands that are not selectable in the current operating states of the target devices are thereby never determined as the uttered command. This results in decreasing unreasonable and unpleasant feeling of the user in voice manipulation.
