Hello!!!
We asked for it, and now we finally have weekly builds for the new Kinect V2 SDK. Now the interesting thing is that we have tons of interesting work in each release to review what you have inside. So today, a small review of something that already exists in Kinect SDK V1.8 and needed in V2: Speech Recognition.
The basis is simple and safe that you know, create a dictionary with words within the same. The interesting thing is that we make the Association of the audio feed of Kinect with the speech grammar defined in line 5 in line 18

Another important point is the section for the KinectRecognizer at the end. To see if when I arrive to Madrid I make a cool video 😀
