With the advancement of technologies, an Automatic Lip reading system has always been requirement in various safety and security concerned systems. Moreover under noisy conditions it plays a very important role for listeners with a hearing impairment. Study of techniques associated with various Visual Speech Recognition Systems, which are developed till now, is done in this paper. Results associated with lip feature extraction techniques, employed in these systems, are analyzed. On the basis of analysis, it is found, that accuracy of Lip Geometry Estimation and Image Based Raw Information Techniques are 91% and 92-93% respectively. Hence on an average these techniques are giving best results for lip feature extraction.
