Abstract :
In this paper a technique for eradicating the problem of lip synchronization has been discussed. When motion in an image sequence is large, the present day videophone systems are unable to maintain synchronization of the lips and the corresponding acoustic signal. By exploiting the correlation found between the speech and image data, the problem of lip synchronization is addressed and the mouth and speech signals may be transmitted in the same packet
