PROBLEM TO BE SOLVED: To accurately recognize words based on the movement of a mouth.

SOLUTION: In a lip reading device, a similarity detection part 181 detects the similarity between the mouth shape of a user in a mouth shape image and a plurality of types of basic mouth shapes. A mouth shape period detection part 191 detects an initial mouth shape period when an initial mouth shape appears and a final mouth shape period when a final mouth shape appears based on the similarity. A basic score calculation part 192 calculates basic scores showing the similarity between the mouth shape of a user in each period and each basic mouth shape. A recognition part 172 calculates recognition scores showing probability that each word/phrase registered in a mouth shape dictionary is spoken by the user by using the basic scores. Therefore, this invention may be applied to a lip reading device which recognizes words based on the movement of the mouth.
