Voice commands

Today's information devices have the voice operation function. This is very beneficial for the persons with difficulties on access (ex. persons with visual impairment, upper-limb impairment, etc.). However, if the voice commands are not unified, or speech recognition is poor, the information devices cannot understand the voice commands. To avoid such problems, various standards about voice commands are published.

These functions are defined in ISO 9241-171. However, there is problem that the user interfaces to open and/or set these functions are not accessible.
