Background and Aim: Speech is a multi-dimensional process. Human speech perception mechanism uses visual and auditory signals to decode the produced speech. While a normal speech is heard by a person, it is also simultaneously visualized, as the processing areas in the brain combine the visual and auditory data related to the speech. The visual data received from the face and mouth of the speaker has an important role in speech comprehension. Lip reading in word means the cognition of spoken words using data such as lip movements. The lips provide more than half of the visual data. This is considered as a normal skill in individuals with normal hearing. In fact, the goal of lip reading is to increase the independence level in those with hearing defect. When lip reading is required (e.g. a sudden deafness), lip reading softwares can be used to teach lip reading. The current review was an attempt to reveal the importance of lip reading in verbal communication (speech recognition) and to propound lip reading techniques and softwares based on the latest clinical researches.
Materials and Methods: The present review study used the latest articles and books issued from 1979 to 2015 in the field of lip reading in verbal communication and speech recognition selected from Googlescholar, SID, Scopus, and Pubmed data banks.
Conclusion: It was found that visual data of the speaker's mouth and face plays an important role in speech comprehension by the audience; in fact, lip reading provides the visual data. It is adived that the role of vision in decoding speech lip reading be used in auditory rehabilitation and especially in verbal communication enhancement. There are also some techniques and softwares for teaching this skill to the individuals suffering from auditory deficit.
