Integrated Optimization of Feature Transformation for Speech Recognition

Stephan Euler

Bosch Telecom, Frankfurt, Germany

In this paper we present an new approach for obtaining an optimal linear transformation of feature vectors. The generalized probabilistic descent method is used in order to optimize the elements of a transformation matrix with respect to a functional approximation of the recognition rate of the training data. The approach is tested in a speaker dependent recognizer for spelled names.
