Scorer

The Scorer task measures the accuracy of a speech recognition transcript (such as that generated by the SpeechToText task), when given a reference transcript file. The task reports scores for general word precision, recall, and the F-measure. You can choose the level of detail that the response includes.

Example

http://localhost:13000/action=AddTask&Type=Scorer&TxtFile=C:\data\RefTranscript.txt&CtmFile=C:\misc\Stt.ctm&ScoreFile=score&Out=FinalTranscript.ctm

This action uses port 13000 to instruct HPE IDOL Speech Server, which is located on the local machine, to score the Stt.ctm recognition transcript by comparing it to the RefTranscript.txt file. The action instructs HPE IDOL Speech Server to write the truth transcript containing timestamps to the FinalTranscript.ctm file and the scores to the score.ctm file.
