Tools for the analysis of benchmark speech recognition tests

The development of tools for the analysis of benchmark speech recognition system tests is reported. One development is a tool implementing two statistical significance tests. Another involves studies of an alternative to the alignment process presently used in the DARPA/NIST scoring software (which presently minimizes a weighted sum of elementary word error types). The alternative process minimizes a measure of phonological implausibility. The purpose in developing a standard implementation of these tools is to make these tools uniformly available to system developers.<
