Abstract

In this work, the problem of speech decoding is viewed in a Decision Theoretic framework. A modified speech decoding procedure to minimize the expected word error rate is formulated in this framework, and its implementation in N-best list rescoring is presented. Preliminary experiments on the Switch-board show a small but statistically significant error rate improvements.
