The analysis of sign language covers different areas such as audio and image processing, pattern recognition, natural language processing that require complex computational processing. These processes required recognizing the sign and audio, plays an important role in development of human-computer interaction. In this paper we focused on automatic lipreading by utilizing visual information in speech recognition. Some approaches about finding lip area, tracking lip contours and obtaining required features about automatic lipreading are suggested.
