Audio-visual recognition of spectrally reduced speechFrédéric Berthommier

SpeechReading

A human listener can use visual cues, such as lip and tongue movements, to enhance the level of speech understanding, especially in a noisy environment. The process of combining the audio modality and the visual modality is referred to as speechreading, or lipreading.

There are many applications in which it is desired to recognize speech under extremely adverse acoustic environments. Detecting a person's speech from a distance or through a glass window, understanding a person speaking among a very noisy crowd of people, and monitoring a speech over TV broadcast when the audio link is weak or corrupted, are some examples.
