A. Kannan et M. Ostendorf, A COMPARISON OF CONSTRAINED TRAJECTORY SEGMENT MODELS FOR LARGE VOCABULARY SPEECH RECOGNITION, IEEE transactions on speech and audio processing, 6(3), 1998, pp. 303-306
This paper compares parametric and nonparametric constrained-mean traj
ectory segment models for large vocabulary speech recognition, extendi
ng distribution clustering techniques to handle polynomial mean trajec
tory models for robust parameter estimation. The parametric model has
fewer free parameters and gives similar recognition performance to the
nonparametric model, but has higher recognition costs.
