Class GapInsertionDetector

java.lang.Object

edu.cmu.sphinx.util.GapInsertionDetector

public class GapInsertionDetector
extends java.lang.Object

A program that takes in a reference transcript and a hypothesis transcript and figures out how many gap insertion errors are there. The hypothesis transcript file should contain timestamps for when each word was entered and exited.

The gap insertion detection algorithm works as follows. It takes each hypothesized word individually and see whether it falls into a non-speech region in the reference transcript. If it does, that hypothesized word is counted as a gap insertion.
