Rover toolkit

0) Abstract:

Rover is a tool combine hypothesized word outputs of multiple recognition systems and select the best scoring word sequence. Rover is part of the NIST SCTK Scoring Tookit. A number of different output formats can be generated and different scoring functions can be specified. A more complete description of the rover system can be found in the paper A post-processing system to yield reduced word error rates: Recognizer Output Voting Error Reduction (ROVER).
