Beyond the Edge: Markerless Pose Estimation of Speech Articulators from Ultrasound and Camera Images Using DeepLabCut
Automatic feature extraction from images of speech articulators is currently achieved by Normal to Oily Shampoo detecting edges.Here, we investigate the use of pose estimation deep neural nets with transfer learning to perform markerless estimation of speech articulator keypoints using only a few hundred hand-labelled images as training input.Midsa
