A home automation hobbyist has used his small Raspberry Pi and a series of switches from LightwaveRF to provide a simple voice control system for some of his devices in his home.
Specifically, the combination of these two elements allows, for example, to control the degree of illumination of the lamps in our home but also the activation or deactivation of plugs. To offer voice control, use is made of the Open Source CMU Sphinx software, which has been available for a long time thanks to the work of researchers at Carnegie Mellon University. Furthermore, this engine works in conjunction with Festival, an application developed by the University of Edinburgh that responds to some of the commands with a computer-generated voice.
To complete the assembly it is necessary to make use of the GPIO port of the Raspberry Pi, which once again demonstrates its potential as small multipurpose computers.
