Utility for generating word segmentation by forced alignment

Given a CTL file that specifies a series of audio and coresponding correct transcripts, this utility creates a trivial grammar from the transcript, and runs the recognizer on the utterance. The output is words with beginning and end times.

See BatchNISTRecognizer for more information about the format of CTL and audio files.
