Visual speech recognition using active shape models and hidden Markov models

  title={Visual speech recognition using active shape models and hidden Markov models},
  author={Juergen Luettin and Neil A. Thacker and Steve W. Beet},
This paper describes a novel approach for visual speech recognition. The shape of the mouth is modelled by an Active Shape Model which is derived from the statistics of a training set and used to locate, track and parameterise the speaker’s lip movements. The extracted parameters representing the lip shape are modelled as continuous probability distributions and their temporal dependencies are modelled by Hidden Markov Models. We present recognition tests performed on a database of a broad… CONTINUE READING
