A building construction drawing system incorporates a voice activated
command recognition and actuation module to enable a building
construction system designer, such as a fire sprinkler system designer,
to be able to draw building construction systems, or components thereof,
using simple and easy to remember voice commands. This building
construction drawing system is easier and faster for the designer to
learn and to use effectively because the designer does not need to know
or learn how to find the command he or she wants using a traditional
mouse or keyboard input device, which can be cumbersome and slow.
