Before revision:  Although each language has its own linguistic and pronunciation features , the lip movements of all languages share similar patterns  . Based on this idea, in this paper, we try to explore the synergized learning of multilingual lip reading  , and further propose a synchronous bidirectional learning (SBL) framework for effective synergy of multilingual lip reading.
