Robust methods for using context-dependent features and models in a continuous speech recognizer
Abstract
In this paper we describe the method we use to derive acoustic features that reflect some of the dynamics of frame-based parameter vectors. Models for such observations must be context dependent. Such models were outlined in an earlier paper. Here we describe a method for using these models in a recognition system. The method is more robust than using continuous parameter models in recognition. At the same time it does not suffer from the possible information loss in vector quantkation based systems.
