Abstract
In this paper we present a set of experiments that were aimed at investigation of feasibility of using artificial neural networks (ANNs) in a lip-reading task. We present here the method for data extraction that is applied on video sequences containing lower half of the face of speaking subject. Further the data is used to evaluate the performance of ANNs in a task of classifying the frames in the video stream into three possible classes: vowel, consonant or silence.
