Lipreading

Lip reading is a process of extracting speech by observing the lip movements of a speaker in a silent state. It is an important component of human communication, especially valuable for those with hearing impairments. Deep lip reading utilizes deep neural networks to extract speech from silent videos, also known as Visual Speech Recognition (VSR), machine lip reading, or automatic lip reading. The process mainly consists of two stages: one is to extract visual and temporal features from a sequence of video frames; the other is to process these features into speech units such as characters, words, or phrases. Deep lip reading technology can be applied to multiple fields, enhancing communication efficiency and accessibility.
