Bartoš, T. and Müller, L. : Rejection technique based on the mumble model . Lecture Notes in Artificial Intelligence, 2448, p. 221-228, 2002.


A technique for detection and rejection of incorrectly recognized words is described. The used speech recognition system is based on a speaker-independent continuous density Hidden Markov Model recognizer and so-called mumble model. The new method is fully statistically based. Therefore selection of features for training and classification, procedures for statistical models parameters estimation, and experimental results are reported. The rejection technique achieves approximately 12% equal error rate in detection of incorrectly recognized words.
