CoALT

CoALT (Comparing Automatic Labeling Tools) compares two automatic labelers or two speech-text alignment tools, ranks them and displays statistics about their differences. The main feature of our software is that a user can define its own criteria for evaluating and comparing two speech- text alignment tools. With CoALT, a user can give more importance to either phoneme labels or phoneme boundaries because the CoALT elastic comparison algorithm takes into account time boundaries. Moreover, by providing a set of phonetic rules, a user can define the allowed discrepancies between the automatic labeling result and the hand-labeling one.
