Don't stop him now!
Ohbot sings Queen song
In this video, the Ohbot Pi sings the intro of Don’t Stop Me Now by Queen. Lip aperture was automatically computed from voice signal amplitude, and the Ohbot’s head goes up and down following the pitch of the melody. In the Github repo, I uploaded the Matlab script (signal2Lips.m) I wrote for this video as well as the Pitch file (dontStopPitch.txt, obtained with the Praat program). Hopefully the comments in the script will clarify the whole process !
