    Abstract

    Visemes are groups of phonemes that are considered visually indistinguishable, but there are many doubts regarding their use in visual speech recognition. In this thesis, a visual speech recogniser is constructed to test the validity of visemes. Examining the phoneme output of the recogniser shows that it is not possible to construct a viseme grouping that exhibits the required phoneme confusion characteristics. This thesis proves that phonemes, not visemes, are the basic visual unit of speech.
