A two-channel training algorithm for hidden Markov model to identify visual speech elements. In Proceedings of the International Symposium on Circuits and Systems 2003: (pp.572-575). Singapore. | Conference: | IEEE International Symposium on Circuits and Systems (2003 : Bangkok, Thailand) | Abstract: | A novel two-channel algorithm is proposed in this paper for discriminative training of Hidden Markov Models (HMMs). It adjusts the symbol emission coefficients of an existing HMM to maximize the separable distance between a pair of confusable training samples. The method is applied to identify the visemes of visual speech. The results indicate that the two-channel training method provides better accuracy on separating similar visemes than the conventional Baum-Welch estimation. | URI: | https://hdl.handle.net/10356/90658 http://hdl.handle.net/10220/5843 |
