[Arthur] was laid up with a wrist injury, so he decided it would be a great time to hang out around the house and tinker with electronics, since most outdoor activities were out of the question. He picked up a robotic arm kit and assembled it to test out some code written for it that he found online. Since typing commands into a terminal was awfully cumbersome considering his injury, he figured he might as well construct a voice control system for the arm.
He documents his work in a three part series, covering the process from concept to completion. The first part centers around the creation of the vocabulary and grammar for the voice recognition system, along with the how the grammar model was trained using voice samples.
[Arthur’s] voice control system works pretty well as you can see in the video below, though he already has a wish list full of improvements he hopes to make in the near future.
