# JunkThresh

The threshold for identifying words in adaptation data as junk.

The `AmTrain` task compares each audio file with its user-supplied transcript and attempts to align each word it recognizes in the audio with its counterpart in the transcript. IDOL Speech Server produces a score that represents how closely the recognized word resembles the word in the transcript. If the words match exactly, the alignment score is zero (0). The higher the score, the more differences there are between the two words. The `JunkWordThreshold` parameter sets the score above which words are identified as junk. For example, if `JunkWordThreshold` is set to `2`, any words with an alignment score greater than 2 are labeled as junk.

This parameter is available only if the Junk parameter is set to `True`.
